Definitions
- This invention relates to an ophthalmic lens system which comprises ophthalmic lenses.
- the ophthalmic lenses may be adapted for implantation in an eye such as intraocular lenses (IOLS) or adapted to be disposed on or in the cornea such as contact lenses or corneal inlays.
- IOLS intraocular lenses
- the natural lens of the eye When functioning normally, the natural lens of the eye is somewhat elastic and therefore enables good vision of objects at all distances. This accommodation of the natural lens tends to deteriorate with age such that the ability to see well at all distances is lost and eventually the natural lens becomes basically monofocal.
- the IOL may be multifocal as shown and described, for example, in Portney U.S. Pat. No. 5,225,858, Roffman et al U.S. Pat. No. 5,448,312 or Menezes et al U.S. Pat. No. 5,682,223.
- the IOL may be of the type which is accommodating in that it can be moved by the eye itself, or monofocal with a depth of focus feature as shown and described in Portney U.S. Pat. No. 5,864,378.
- ophthalmic lenses such as contact lenses or IOLS
- IOLS ophthalmic lenses
- one lens has a distance vision correction power and the other lens has a near vision correction power.
- Roffman et al U.S. Pat. No. 5,485,228 It is also known to implant a distant dominant multifocal IOL in one eye and a near dominant multifocal IOL in the other eye as disclosed in the January 1999 issue of Clinical Sciences by Jacobi et al entitled “Bilateral Implantation of Asymmetrical Diffractive Multifocal Intraocular Lenses,” pages 17-23.
- Ophthalmic multifocal lenses can also be provided with some depth of focus. This is shown and described, for example, in Portney U.S. Pat. No. 5,225,858 and Roffman et al U.S. Pat. No. 5,684,560.
- nighttime images may not be the same for both eyes and/or possess halos as when the headlights of an oncoming vehicle are observed. This can significantly reduce the ability of the observer to identify and locate objects near the headlights. For example, halos tend to be created when the patient views a distant object through the near vision portion of the lens, and the greater the add power, the more perceptible is the halo.
- This invention provides an ophthalmic lens system which improves the ability of the observer to identify and locate objects at near.
- the invention also significantly reduces nighttime visual phenomena associated with receiving out of focus simultaneous images from multifocal IOLS and obtains other important advantages.
- the ophthalmic lens system of this invention may include first and second lenses for use with first and second eyes of a patient, respectively.
- Each of the first and second lenses has more than one vision correction power and is therefore multifocal.
- this invention is particularly adapted for IOLS, it is also applicable to lenses which can be disposed on or in the cornea such as contact lenses and corneal inlays.
- the first lens is biased for distance vision or distance biased. This may be accomplished, for example, by configuring the first lens so that the best visual acuity provided by the lens is for distant objects, for example, objects at infinity.
- the first lens provides better visual acuity for objects at infinity than the second lens.
- the first lens substantially optimizes visual acuity from distance to intermediate distances.
- the first lens has a power including a power required for distance vision correction for the patient.
- the second lens has a power including a power required for intermediate vision correction for the patient.
- the second lens preferably is intermediate biased. This may be accomplished, for example, by configuring the second lens so that the best visual acuity provided by the second lens is for objects at intermediate distances.
- the second lens provides better visual acuity from intermediate to near distances than the first lens.
- the second lens enhances visual acuity from intermediate to near distances.
- this enhanced visual acuity of the second lens significantly enhances intermediate vision and provides functional near image quality. It also minimizes potential undesirable effects by using only a low level of image quality disparity between the images received by the two eyes.
- the lenses can be made to have the relatively larger ranges of vision in various ways. For example, this can be accomplished by appropriately splitting the light between distance and intermediate.
- the second lens may focus sufficient light to an intermediate focus region so as to contribute to the second lens providing enhanced vision from intermediate to near distances.
- the depth of focus of the zone or zones of the lens which provide intermediate vision correction may be appropriately increased to make the second lens have enhanced vision from intermediate to near distances. This may be accomplished, for example, by controlling the aspheric surface design of the lenses. More specifically, the second lens may have a zone with an add power for intermediate vision correction with such zone having optical aberrations which increase the depth of focus of such zone. In one preferred embodiment, such zone extends radially outwardly and has progressively increasing add powers as the zone extends radially outwardly.
- the add power of the lenses is reduced over what it would be if one or both of the lenses had the full or even nearly full add power required for near vision correction.
- the full add power for near vision correction can range from greater than about 1.75 diopters of add power, and is typically between about 2.0 diopters or about 2.5 diopters to about 3.0 or more diopters of add power.
- the reduced add power significantly reduces halos.
- the invention is embodied in an IOL which is implanted in a phakic eye with some accommodation, the near visual quality is even better.
- the maximum add power of either or both of the first and second lenses is less than the add power required for complete or full near vision correction. Still more preferably, the maximum power of any region of either or both of the first and second lenses is no greater than about the power required for intermediate vision correction.
- the maximum add power for both the first and second lenses may be from about 0.5 diopter to about 1.75 diopters and is preferably from about 1 diopter to about 1.5 diopters.
- the complete near vision correction is typically between 2.5 and 3.0 diopters of add power. All of the add powers set forth herein are in the spectacle plane.
- the first and second lenses are adapted to provide some depth of focus.
- the first lens provides some depth of focus toward intermediate vision correction and preferably the second lens also provides some depth of focus from far vision correction toward intermediate vision correction.
- Each of the first and second lenses has an optical axis.
- the power of the first lens is different at a plurality of locations radially outwardly of the optical axis of the first lens
- the power of the second lens is different at a plurality of locations radially outwardly of the optical axis of the second lens.
- the power of each of the first and second lenses changes along a power curve, for example, in a radially outward direction from the associated optical axis.
- the power curve for the first lens is different from the power curve for the second lens.
- the power curve of the first lens may at least contribute to the first lens having good visual acuity from distance to intermediate distances and the power curve of the second lens may at least contribute to the second lens having good visual acuity from intermediate to near distances.
- Each of the first and second lenses may have a power which varies from about the power required for far vision correction to about a power required for intermediate vision correction.
- the first lens has a larger range of vision for distance to intermediate distances than the second lens.
- the second lens has a larger range of vision for intermediate to near distances than the first lens.
- the first lens has first, second and third optical zones arranged radially with respect to the optical axis of the first lens with the second zone being intermediate or between the first and third zones and having a greater add power than either of the first and third zones.
- the second lens has first, second and third optical zones arranged radially with respect to the optical axis of the second lens with the second zone being intermediate the first and third zones and having a greater add power than either of the first and third zones of the second lens.
- the zones can be of various configurations, they are preferably substantially annular and substantially concentric. Preferably, there are at least two zones. Still more preferably, there are three or five of the zones with the innermost and outermost of the zones having a power for far vision correction.
- each of the second zones has a power which is substantially constant, and the area, for example, the annular area, of the second zone of the second lens is larger than the area of the second zone of the first lens. This also contributes to the second lens having better visual acuity from intermediate to near than the first lens.
- IOLS constructed in accordance with this invention may be implanted following removal of the natural lenses, they are particularly adapted for implantation in phakic eyes having some residual accommodation. Even though the lenses of this invention have a reduced add power, the additional optical power provided by the natural lens of the early presbyope allows excellent visual quality from distance through intermediate to near. With the gradual loss of accommodation with age, the image quality at near will decrease but some visual acuity will remain even for the absolute presbyope, i.e. a patient with total loss of accommodation.
- first and second IOLS having different optical characteristics are implanted in the eyes, respectively, of the patient without removing the natural lenses of the patient.
- Each of the IOLS has a power required for far vision correction and a power required for intermediate vision correction power with the maximum power of each of the first and second IOLS being less than the add power required for near vision correction for the patient.
- first and second ophthalmic lenses are placed on or in the eyes of a patient with the first lens being distance biased and the second lens being intermediate biased.
- first and second lenses may be contacts or corneal inlays, the features of this invention are particularly adapted for IOLS which can be implanted, respectively, in the eyes of the patient.
- FIG. 1 is a somewhat schematic elevational view of one embodiment of an IOL constructed in accordance with this invention which is substantially optimized for distance-to-intermediate vision.
- FIG. 2 is a view similar to FIG. 1 of one embodiment of an IOL constructed in accordance with this invention which is enhanced for intermediate to near vision.
- FIG. 3 is a side elevational view of the IOL of FIG. 1.
- FIG. 4 is a plot of add power of the IOL of FIG. 1 versus radial distance squared from the optical axis of that IOL.
- FIG. 5 is a plot similar to FIG. 4 for the IOL of FIG. 2.
- FIG. 6A is a plot of visual acuity versus add power for the IOL of FIG. 1 when implanted in an early presbyope needing 1.5 diopters of add power.
- FIG. 6B is a plot similar to FIG. 6A for the IOL of FIG. 2 for the same early presbyope.
- FIG. 6C is a plot similar to FIG. 6A for binocular vision for the same early presbyope.
- FIGS. 7A, 7B and 7 C are plots similar to FIG. 6A, 6B and 6 C, respectively, for the IOLs of FIGS. 1 and 2 implanted in an absolute presbyope.
- FIG. 8 is a sectional view of an eye with the natural lens in place and the intraocular lens of FIG. 1 implanted in the anterior chamber.
- FIG. 1 shows an optimized distance-to-intermediate multifocal IOL 11 and FIG. 2 shows an enhanced intermediate-to-near multifocal IOL 13 which together with the IOL 11 form a lens pair or ophthalmic lens system for improving the vision of a patient.
- the IOL 11 includes a multifocal lens body or optic 15 an optical axis 16 and having powers for a vision correction as described more fully hereinbelow.
- the IOL 11 also includes generally radially extending footplate-type fixation members 17 which, in this embodiment, are integral with the lens body 15 such that the IOL 11 is one piece.
- fixation members 17 and 18 A variety of configurations can be employed for the fixation members 17 and 18 in order to provide for effective fixation of the IOL 11 in the eye. If the IOL 11 is to be implanted following removal of the natural lens from the eye, then any of those configurations known in the art for that purpose may be employed. On the other hand, if the IOL 11 is to be implanted without removal of the natural lens from the eye, i.e. in an early presbyope, then the fixation members 17 and 18 should be of a configuration and construction which will allow the IOL 11 and the natural lens of the eye to usefully coexist in the eye. In that regard, the configuration shown in FIG. 1 or any of the configurations shown by way of example in commonly assigned application Ser. No.
- the IOL may be fixated to the iris of the eye, may be located in the anterior or posterior chamber of the eye and/or may be fixated at the sulcus of the eye.
- the fixation members 17 and 18 may be made of materials of construction, such as polymeric materials, for example, acrylic, polypropylene, silicone, polymethylmethacrylate and the like, many of which are conventionally used in fixation members.
- each of the fixation members 17 and 18 has the form shown by way of example in FIGS. 1 and 3, and this adapts the IOL 11 for implantation in the anterior chamber of the eye without removal of the natural lens as shown and described hereinbelow in connection with FIG. 8.
- the lens body 15 may be constructed of rigid biocompatible materials such as polymethylmethacrylate (PMMA), or flexible, deformable materials, such as silicone polymeric material, acrylic polymeric material, hydrogel polymeric material and the like, which enable the lens body to be rolled or folded before insertion through a small incision into the eye.
- PMMA polymethylmethacrylate
- deformable materials such as silicone polymeric material, acrylic polymeric material, hydrogel polymeric material and the like, which enable the lens body to be rolled or folded before insertion through a small incision into the eye.
- the lens body 15 shown in FIG. 1 is a refractive lens body, it may be diffractive if desired.
- the lens body 15 has a convex anterior surface 19 and a substantially plano posterior surface 21 ; however, these configurations are merely illustrative.
- the vision correction power may be placed on either of the surfaces 19 or 21 , in this embodiment, the anterior surface 19 is appropriately shaped to provide the desired vision correction powers.
- the IOL 13 similarly has a multifocal lens body 23 and fixation members 25 and 26 suitably joined to the lens body 23 .
- the optical characteristics of the lens bodies 15 and 23 are different as described more specifically herein below. However, except for the optical characteristics of the lens bodies 15 and 23 , the IOLs 11 and 13 may be identical.
- the IOL 11 has a central zone 27 and additional optical zones 29 , 31 , 33 and 35 .
- the central zone 27 is circular and the lens body 15 has a circular outer periphery.
- the additional optical zones 29 , 31 , 33 and 35 are annular and concentric with the central zone 27 , and all of these zones are centered on the optical axis 16 .
- the central zone 27 and the outermost annular zone 35 have a base diopter power which is the power required by the patient for distance vision correction and is considered as a zero add power.
- the diopter power variation shown in FIGS. 4 and 5 is applicable to any point on the surface of the lens bodies 15 and 23 , respectively, at a fixed radial distance from the associated optical axes. In other words, the power at any given radial distance from the optical axis 16 is the same, and the power at any given radial distance from the optical axis 38 is the same.
- the annular zone 31 has about the power required for distance vision correction.
- the annular zone 31 could have precisely the power required for distance vision correction, i.e. zero add power
- the power of the annular zone 31 decreases progressively and slightly from the outer edge of the zone 29 to about the inner edge of the zone 33 to provide spherical aberration is correction.
- the optical power of the zone 31 does diminish in a radial outward direction in this fashion, it nevertheless is considered to be about the power needed for far or distance vision correction for the patient.
- the vision correction power of the zone 31 may decrease from a zero add power to about 0.25 diopter below the base diopter power.
- the zones 29 and 33 have greater vision correction power than the zones 27 , 31 and 35 and are preferably at or about the power required for intermediate vision correction.
- the power for intermediate vision correction would be halfway between the base diopter power and the add power for near vision correction.
- the power for intermediate vision correction would be 1.5 diopters of add power.
- the intermediate vision correction power may be taken to embrace a zone of from about 0.5 diopter to about 1.75 diopters and preferably that zone may be from about 1 diopter to about 1.5 diopters.
- the power of the zones 29 and 33 would all be add powers for intermediate vision correction.
- the vision correction power in the zone 29 reduces progressively and slightly in a radial outward direction from an add power for intermediate vision correction such as 1.5 diopters as shown in FIG. 4 to a slightly less add power for intermediate vision correction so as to provide for spherical aberration correction.
- the maximum power of the zone 33 is about the minimum power of the zone 29 and reduces progressively and slightly in a radial outward direction as shown in FIG. 4.
- the power of the zone 29 may decrease linearly from about 1.5 diopters to about 1.25 diopters and the vision correction power of the zone 33 may reduce linearly in a radial outward direction from about 1.25 diopters to about 1.0 diopter.
- all of the powers of the zones 29 and 33 may be considered as add powers for intermediate vision correction.
- the maximum power of any region of the first lens is no greater than about the power for intermediate vision correction.
- the annular areas of the distance correction zones 27 , 31 and 35 are intended to be larger than the annular areas of the intermediate power zones 29 and 33 . Moreover, there are three of the distance power zones 27 and 35 and only two of the intermediate vision correction zones 29 and 33 , although other numbers of these zones may be employed, if desired. Thus, a larger surface of the lens body 15 is dedicated to focusing or directing light to a far focus region than any other focus region. Accordingly, the IOL 11 provides very good visual acuity from distance to intermediate, and provides better visual acuity for objects at infinity than the IOL 13 . The IOL 11 is optimized for distance to intermediate vision.
- the lens body 23 of the IOL 13 has a circular outer periphery, an optical axis 38 , a circular central zone 37 and optical zones 39 , 41 , 43 and 45 which are preferably annular and concentric with the central zone 37 . All of these zones 37 , 39 , 41 , 43 and 45 are centered on the optical axis 38 .
- the nature of the optical zones 37 , 39 , 41 , 43 and 45 makes the lens body 23 optically different from the lens body 15 , but except for this the IOLs 11 and 13 may be identical, if desired. It can be seen from FIG.
- the intermediate annular zone 41 has about the base diopter power. More specifically, the annular zone 41 has a maximum power which is the base diopter power and the vision correction power of this zone decreases progressively in a radial outward direction to a diopter power which is slightly less than the base diopter power in order to correct for spherical aberrations.
- the minimum power of the zone 41 may be 0.25 diopter below the base diopter power.
- the zones 39 and 43 have a vision correction power which is about the add power for intermediate vision correction.
- the vision correction power increases progressively in a radial outward direction.
- the minimum power of each of the zones 39 and 43 may be about 1.25 diopters and the maximum power at the radial outer edge of each of these zones may be about 1.75 diopters.
- the IOL 13 has enhanced intermediate to near vision.
- the intermediate power zones 39 and 43 are provided with optical aberrations which increase the depth of focus of such zone.
- the progressively increasing vision correction powers in a radial outward direction in these zones 39 and 43 increase the spherical aberrations which in turn increases the depth of focus by effectively creating stronger diopter power at radial outward locations in each of these zones to therefore allow closer objects to be in focus.
- This has the effect of increasing the near visual quality at the expense of the intermediate image quality, thereby raising the overall image quality as described more fully hereinbelow in connection with FIG. 6A-C and 7 A-C.
- this increased depth of focus contributes to making the IOL 13 biased or enhanced for intermediate to near vision and certainly more enhanced for intermediate to near vision than the IOL 11 which has spherical aberration correction.
- the IOL 13 provides better visual acuity from intermediate to near than the IOL 11 .
- the IOL 11 is biased or optimized for distance to intermediate vision and certainly provides better visual acuity for distance to intermediate than the IOL 13 .
- a larger portion of the area of the lens body 23 is used to direct light to an intermediate focus region so as to contribute to the lens body 23 having better visual acuity from intermediate to near than the IOL 11 .
- the combined areas, that is the combined annular areas, of the zones 39 and 43 are greater than the combined areas of the zones 37 , 41 and 45 , and this is shown in FIGS. 2 and 5. Consequently, more of the incident light is directed to an intermediate focus region than to a distance or far focus region, and this also contributes to the IOL 13 providing better visual acuity from intermediate to near than the IOL 11 and to providing enhanced intermediate-to-near image quality.
- FIGS. 1 it can also be seen from FIGS.
- the maximum powers of any region of either of the IOLs 11 and 13 are less than the add power required for full near vision correction, the latter being an add power which is at least greater than 1.75 diopters and may be 2.5 or 3.0 diopters. Also, the maximum powers of any region of either of the IOLs 11 and 13 are no greater than about the intermediate vision correction power.
- the plots of FIGS. 4 and 5 represent power curves showing how the vision correction power of each of the IOLs 11 and 13 changes in a radially outward direction from the optical axes 16 and 38 , respectively, and it is apparent that the power curves of FIGS. 4 and 5 are different. Moreover, the differences in these power curves contribute to the range of vision characteristics of IOLs 11 and 13 .

Also, by comparing FIGS. 7A and 7B, it can be seen that the IOL 13 provides better visual acuity for objects at near distances than the IOL 11 .
- FIG. 7B shows that the best visual acuity provided by the IOL 13 is for objects at intermediate distances such as 67 cm which corresponds to 1.5 diopters of add power.
- the binocular visual acuity remains functional or better for distance and intermediate objects. However, near reading between 40 centimeters and 33 centimeters becomes difficult. Thus, the absolute presbyope should perform all active tasks well including screening of mail. However, it is likely that about a 1 diopter to 1.5 diopter add power will be needed for extended near work. Nevertheless, the intermediate and near visual acuity for the absolute presbyope is significantly better than the equivalent presbyope without the IOLs 11 and 13 or near vision correction.
- the intermediate eye has no near vision peak, but only an intermediate peak at about 1.5 diopters or about 67 cm. Accordingly, the only way to increase the near image quality for the absolute presbyope is to increase the depth of focus of the intermediate peak to thereby increase the intermediate to near range of useable image quality.
- the depth of focus of the intermediate peak in FIG. 7B can be increased in two ways.
- the shape of the surfaces of the zones 39 and 43 which provide the intermediate vision correction powers can be altered as shown by way of example in FIG. 5 to introduce optical aberrations, e.g., spherical aberrations, which extend the depth of focus but decrease the overall optical quality.
- optical aberrations e.g., spherical aberrations
- many patients can tolerate clinically significant amounts of refractive error, e.g., up to ⁇ 1 diopter, without seeking refractive correction.
- the visual acuity for intermediate vision can be increased at the expense of distance image quality thereby raising the overall image quality and extending the depth of focus in the useable range of vision. This to some extent counters the decrease in intermediate visual quality associated with an increase in depth of focus by the introduction of optical aberration.
- the visual acuity for intermediate distances is increased by increasing the amount of light directed to the intermediate zones 39 and 43 , as described above in connection with FIG. 5.
Abstract
An ophthalmic lens system for improving the vision of a patient comprising first and second ophthalmic lenses. Each of these lenses is adapted for implantation in an eye or to be disposed on or in the cornea. The first ophthalmic lens is biased for distance vision and the second ophthalmic lens is biased for intermediate vision. The ophthalmic lenses may be intraocular lenses which are implanted in the eyes of a patient without removal of the natural lens.
Description
- This invention relates to an ophthalmic lens system which comprises ophthalmic lenses. The ophthalmic lenses may be adapted for implantation in an eye such as intraocular lenses (IOLS) or adapted to be disposed on or in the cornea such as contact lenses or corneal inlays.
- When functioning normally, the natural lens of the eye is somewhat elastic and therefore enables good vision of objects at all distances. This accommodation of the natural lens tends to deteriorate with age such that the ability to see well at all distances is lost and eventually the natural lens becomes basically monofocal.
- Likewise, when the natural lens is removed as a result of disease or injury and replaced with an IOL, the natural ability of the eye to accommodate is lost completely. However, an ability to have adequate vision at different distances without using spectacles can be provided by the IOL which is implanted following removal of the natural lens. To this end, the IOL may be multifocal as shown and described, for example, in Portney U.S. Pat. No. 5,225,858, Roffman et al U.S. Pat. No. 5,448,312 or Menezes et al U.S. Pat. No. 5,682,223. Alternatively, the IOL may be of the type which is accommodating in that it can be moved by the eye itself, or monofocal with a depth of focus feature as shown and described in Portney U.S. Pat. No. 5,864,378.
- Another approach to overcoming loss of accommodation is to use ophthalmic lenses, such as contact lenses or IOLS, with different optical characteristics for each eye. For example with a system known as monovision one lens has a distance vision correction power and the other lens has a near vision correction power. Another example is shown and described in Roffman et al U.S. Pat. No. 5,485,228. It is also known to implant a distant dominant multifocal IOL in one eye and a near dominant multifocal IOL in the other eye as disclosed in the January 1999 issue of Clinical Sciences by Jacobi et al entitled “Bilateral Implantation of Asymmetrical Diffractive Multifocal Intraocular Lenses,” pages 17-23.
- Ophthalmic multifocal lenses can also be provided with some depth of focus. This is shown and described, for example, in Portney U.S. Pat. No. 5,225,858 and Roffman et al U.S. Pat. No. 5,684,560.
- Whether monovision or multifocal ophthalmic lenses are employed, nighttime images may not be the same for both eyes and/or possess halos as when the headlights of an oncoming vehicle are observed. This can significantly reduce the ability of the observer to identify and locate objects near the headlights. For example, halos tend to be created when the patient views a distant object through the near vision portion of the lens, and the greater the add power, the more perceptible is the halo.
- For example, this is shown and described in commonly assigned application Ser. No. 09/302,977 filed on Apr. 30, 1999. This application discloses a reduced add power multifocal IOL which reduces the effects of halos. This reduced add power IOL is implanted in a phakic eye in which the natural lens has lost some degree of accommodation, i.e. in partially presbyopic eyes.
- Commonly assigned application Ser. No. ______ (Atty. Docket No.: D-2857) filed concurrently herewith also discloses multifocal reduced add power lenses, such as IOLs, which are asymmetric, i.e. have different optical characteristics. However, one of these lenses has an add power for full near vision.
- The disclosure of each of the patent applications and patents identified herein is incorporated in its entirety herein by reference.
- This invention provides an ophthalmic lens system which improves the ability of the observer to identify and locate objects at near. The invention also significantly reduces nighttime visual phenomena associated with receiving out of focus simultaneous images from multifocal IOLS and obtains other important advantages.
- The ophthalmic lens system of this invention may include first and second lenses for use with first and second eyes of a patient, respectively. Each of the first and second lenses has more than one vision correction power and is therefore multifocal. Although this invention is particularly adapted for IOLS, it is also applicable to lenses which can be disposed on or in the cornea such as contact lenses and corneal inlays.
- The first lens is biased for distance vision or distance biased. This may be accomplished, for example, by configuring the first lens so that the best visual acuity provided by the lens is for distant objects, for example, objects at infinity. The first lens provides better visual acuity for objects at infinity than the second lens. Preferably, the first lens substantially optimizes visual acuity from distance to intermediate distances. The first lens has a power including a power required for distance vision correction for the patient. The second lens has a power including a power required for intermediate vision correction for the patient. The second lens preferably is intermediate biased. This may be accomplished, for example, by configuring the second lens so that the best visual acuity provided by the second lens is for objects at intermediate distances. Alternatively, or in addition thereto, the second lens provides better visual acuity from intermediate to near distances than the first lens. Preferably, the second lens enhances visual acuity from intermediate to near distances. In addition to the advantages noted above, this enhanced visual acuity of the second lens significantly enhances intermediate vision and provides functional near image quality. It also minimizes potential undesirable effects by using only a low level of image quality disparity between the images received by the two eyes.
- The lenses can be made to have the relatively larger ranges of vision in various ways. For example, this can be accomplished by appropriately splitting the light between distance and intermediate. Thus, the second lens may focus sufficient light to an intermediate focus region so as to contribute to the second lens providing enhanced vision from intermediate to near distances.
- Alternatively or in addition thereto, the depth of focus of the zone or zones of the lens which provide intermediate vision correction may be appropriately increased to make the second lens have enhanced vision from intermediate to near distances. This may be accomplished, for example, by controlling the aspheric surface design of the lenses. More specifically, the second lens may have a zone with an add power for intermediate vision correction with such zone having optical aberrations which increase the depth of focus of such zone. In one preferred embodiment, such zone extends radially outwardly and has progressively increasing add powers as the zone extends radially outwardly.
- The add power of the lenses is reduced over what it would be if one or both of the lenses had the full or even nearly full add power required for near vision correction. The full add power for near vision correction can range from greater than about 1.75 diopters of add power, and is typically between about 2.0 diopters or about 2.5 diopters to about 3.0 or more diopters of add power. The reduced add power significantly reduces halos. Moreover, when the invention is embodied in an IOL which is implanted in a phakic eye with some accommodation, the near visual quality is even better.
- In the interest of keeping the add power low while providing adequate vision quality, preferably the maximum add power of either or both of the first and second lenses is less than the add power required for complete or full near vision correction. Still more preferably, the maximum power of any region of either or both of the first and second lenses is no greater than about the power required for intermediate vision correction. By way of example, the maximum add power for both the first and second lenses may be from about 0.5 diopter to about 1.75 diopters and is preferably from about 1 diopter to about 1.5 diopters. The complete near vision correction is typically between 2.5 and 3.0 diopters of add power. All of the add powers set forth herein are in the spectacle plane.
- The first and second lenses are adapted to provide some depth of focus. The first lens provides some depth of focus toward intermediate vision correction and preferably the second lens also provides some depth of focus from far vision correction toward intermediate vision correction.
- Each of the first and second lenses has an optical axis. Preferably the power of the first lens is different at a plurality of locations radially outwardly of the optical axis of the first lens, and the power of the second lens is different at a plurality of locations radially outwardly of the optical axis of the second lens.
- Viewed from a different perspective, the power of each of the first and second lenses changes along a power curve, for example, in a radially outward direction from the associated optical axis. The power curve for the first lens is different from the power curve for the second lens. The power curve of the first lens may at least contribute to the first lens having good visual acuity from distance to intermediate distances and the power curve of the second lens may at least contribute to the second lens having good visual acuity from intermediate to near distances. Each of the first and second lenses may have a power which varies from about the power required for far vision correction to about a power required for intermediate vision correction. In one embodiment, the first lens has a larger range of vision for distance to intermediate distances than the second lens. In the same or a different embodiment, the second lens has a larger range of vision for intermediate to near distances than the first lens.
- In one preferred embodiment, the first lens has first, second and third optical zones arranged radially with respect to the optical axis of the first lens with the second zone being intermediate or between the first and third zones and having a greater add power than either of the first and third zones. Similarly, the second lens has first, second and third optical zones arranged radially with respect to the optical axis of the second lens with the second zone being intermediate the first and third zones and having a greater add power than either of the first and third zones of the second lens.
- Although the zones can be of various configurations, they are preferably substantially annular and substantially concentric. Preferably, there are at least two zones. Still more preferably, there are three or five of the zones with the innermost and outermost of the zones having a power for far vision correction.
- The power in a radial direction can change either gradually or abruptly. The maximum power in each of the second zones may be substantially the same. In one form of the invention, each of the second zones has a power which is substantially constant, and the area, for example, the annular area, of the second zone of the second lens is larger than the area of the second zone of the first lens. This also contributes to the second lens having better visual acuity from intermediate to near than the first lens.
- Although IOLS constructed in accordance with this invention may be implanted following removal of the natural lenses, they are particularly adapted for implantation in phakic eyes having some residual accommodation. Even though the lenses of this invention have a reduced add power, the additional optical power provided by the natural lens of the early presbyope allows excellent visual quality from distance through intermediate to near. With the gradual loss of accommodation with age, the image quality at near will decrease but some visual acuity will remain even for the absolute presbyope, i.e. a patient with total loss of accommodation.
- According to one aspect of the method of this invention first and second IOLS having different optical characteristics are implanted in the eyes, respectively, of the patient without removing the natural lenses of the patient. Each of the IOLS has a power required for far vision correction and a power required for intermediate vision correction power with the maximum power of each of the first and second IOLS being less than the add power required for near vision correction for the patient.
- According to another feature of the method of this invention, first and second ophthalmic lenses are placed on or in the eyes of a patient with the first lens being distance biased and the second lens being intermediate biased. Although the first and second lenses may be contacts or corneal inlays, the features of this invention are particularly adapted for IOLS which can be implanted, respectively, in the eyes of the patient.
- The invention, together with additional features and advantages thereof, may best be understood by reference to the following description taken in connection with the accompanying illustrative drawings.
- FIG. 1 is a somewhat schematic elevational view of one embodiment of an IOL constructed in accordance with this invention which is substantially optimized for distance-to-intermediate vision.
- FIG. 2 is a view similar to FIG. 1 of one embodiment of an IOL constructed in accordance with this invention which is enhanced for intermediate to near vision.
- FIG. 3 is a side elevational view of the IOL of FIG. 1.
- FIG. 4 is a plot of add power of the IOL of FIG. 1 versus radial distance squared from the optical axis of that IOL.
- FIG. 5 is a plot similar to FIG. 4 for the IOL of FIG. 2.
- FIG. 6A is a plot of visual acuity versus add power for the IOL of FIG. 1 when implanted in an early presbyope needing 1.5 diopters of add power.
- FIG. 6B is a plot similar to FIG. 6A for the IOL of FIG. 2 for the same early presbyope.
- FIG. 6C is a plot similar to FIG. 6A for binocular vision for the same early presbyope.
- FIGS. 7A, 7B and7C are plots similar to FIG. 6A, 6B and 6C, respectively, for the IOLs of FIGS. 1 and 2 implanted in an absolute presbyope.
- FIG. 8 is a sectional view of an eye with the natural lens in place and the intraocular lens of FIG. 1 implanted in the anterior chamber.
- FIG. 1 shows an optimized distance-to-intermediate
multifocal IOL 11 and FIG. 2 shows an enhanced intermediate-to-nearmultifocal IOL 13 which together with theIOL 11 form a lens pair or ophthalmic lens system for improving the vision of a patient. TheIOL 11 includes a multifocal lens body or optic 15 anoptical axis 16 and having powers for a vision correction as described more fully hereinbelow. TheIOL 11 also includes generally radially extending footplate-type fixation members 17 which, in this embodiment, are integral with thelens body 15 such that theIOL 11 is one piece. - A variety of configurations can be employed for the
fixation members IOL 11 in the eye. If theIOL 11 is to be implanted following removal of the natural lens from the eye, then any of those configurations known in the art for that purpose may be employed. On the other hand, if theIOL 11 is to be implanted without removal of the natural lens from the eye, i.e. in an early presbyope, then thefixation members IOL 11 and the natural lens of the eye to usefully coexist in the eye. In that regard, the configuration shown in FIG. 1 or any of the configurations shown by way of example in commonly assigned application Ser. No. 09/302,977, filed on Apr. 30, 1999 may be employed. The IOL may be fixated to the iris of the eye, may be located in the anterior or posterior chamber of the eye and/or may be fixated at the sulcus of the eye. Thefixation members fixation members IOL 11 for implantation in the anterior chamber of the eye without removal of the natural lens as shown and described hereinbelow in connection with FIG. 8. - The
lens body 15 may be constructed of rigid biocompatible materials such as polymethylmethacrylate (PMMA), or flexible, deformable materials, such as silicone polymeric material, acrylic polymeric material, hydrogel polymeric material and the like, which enable the lens body to be rolled or folded before insertion through a small incision into the eye. Although thelens body 15 shown in FIG. 1 is a refractive lens body, it may be diffractive if desired. - As shown in FIG. 3, the
lens body 15 has a convexanterior surface 19 and a substantiallyplano posterior surface 21; however, these configurations are merely illustrative. Although the vision correction power may be placed on either of thesurfaces anterior surface 19 is appropriately shaped to provide the desired vision correction powers. - The
IOL 13 similarly has amultifocal lens body 23 and fixation members 25 and 26 suitably joined to thelens body 23. The optical characteristics of thelens bodies lens bodies IOLs - With respect to optical characteristics, it can be seen from FIG. 1 that the
IOL 11 has acentral zone 27 and additionaloptical zones central zone 27 is circular and thelens body 15 has a circular outer periphery. Also, in this embodiment, the additionaloptical zones central zone 27, and all of these zones are centered on theoptical axis 16. - With reference to FIG. 4, it can be seen that the
central zone 27 and the outermostannular zone 35 have a base diopter power which is the power required by the patient for distance vision correction and is considered as a zero add power. It should also be noted that the diopter power variation shown in FIGS. 4 and 5 is applicable to any point on the surface of thelens bodies optical axis 16 is the same, and the power at any given radial distance from theoptical axis 38 is the same. - The
annular zone 31 has about the power required for distance vision correction. Although theannular zone 31 could have precisely the power required for distance vision correction, i.e. zero add power, in this embodiment, the power of theannular zone 31 decreases progressively and slightly from the outer edge of thezone 29 to about the inner edge of thezone 33 to provide spherical aberration is correction. Thus, although the optical power of thezone 31 does diminish in a radial outward direction in this fashion, it nevertheless is considered to be about the power needed for far or distance vision correction for the patient. For example, the vision correction power of thezone 31 may decrease from a zero add power to about 0.25 diopter below the base diopter power. - The
zones zones zones - The vision correction power in the
zone 29 reduces progressively and slightly in a radial outward direction from an add power for intermediate vision correction such as 1.5 diopters as shown in FIG. 4 to a slightly less add power for intermediate vision correction so as to provide for spherical aberration correction. Again, to correct for spherical aberration, the maximum power of thezone 33 is about the minimum power of thezone 29 and reduces progressively and slightly in a radial outward direction as shown in FIG. 4. By way of example, the power of thezone 29 may decrease linearly from about 1.5 diopters to about 1.25 diopters and the vision correction power of thezone 33 may reduce linearly in a radial outward direction from about 1.25 diopters to about 1.0 diopter. Thus, all of the powers of thezones - The annular areas of the
distance correction zones intermediate power zones distance power zones vision correction zones lens body 15 is dedicated to focusing or directing light to a far focus region than any other focus region. Accordingly, theIOL 11 provides very good visual acuity from distance to intermediate, and provides better visual acuity for objects at infinity than theIOL 13. TheIOL 11 is optimized for distance to intermediate vision. - The
lens body 23 of theIOL 13 has a circular outer periphery, anoptical axis 38, a circularcentral zone 37 andoptical zones central zone 37. All of thesezones optical axis 38. The nature of theoptical zones lens body 23 optically different from thelens body 15, but except for this theIOLs central zone 37 and the outerannular zone 45 have the base diopter power, i.e., the power required for distance vision correction for the patient or a zero add power. The intermediateannular zone 41 has about the base diopter power. More specifically, theannular zone 41 has a maximum power which is the base diopter power and the vision correction power of this zone decreases progressively in a radial outward direction to a diopter power which is slightly less than the base diopter power in order to correct for spherical aberrations. By way of example, the minimum power of thezone 41 may be 0.25 diopter below the base diopter power. - The
zones zones zones - In this embodiment, the
IOL 13 has enhanced intermediate to near vision. In this regard, theintermediate power zones zones IOL 13 biased or enhanced for intermediate to near vision and certainly more enhanced for intermediate to near vision than theIOL 11 which has spherical aberration correction. Stated differently, theIOL 13 provides better visual acuity from intermediate to near than theIOL 11. Conversely, theIOL 11 is biased or optimized for distance to intermediate vision and certainly provides better visual acuity for distance to intermediate than theIOL 13. - In addition a larger portion of the area of the
lens body 23 is used to direct light to an intermediate focus region so as to contribute to thelens body 23 having better visual acuity from intermediate to near than theIOL 11. Thus, the combined areas, that is the combined annular areas, of thezones zones IOL 13 providing better visual acuity from intermediate to near than theIOL 11 and to providing enhanced intermediate-to-near image quality. As compared with theIOL 11, it can also be seen from FIGS. 4 and 5 that the area of each of thezones IOL 13 is larger than the area of either of thezones IOL 11. This also contributes to theIOL 13 having better visual acuity from intermediate to near than theIOL 11.IOL 13 is intermediate biased, whereasIOL 11 is distance biased. - From FIGS. 4 and 5, it is apparent that the maximum powers of any region of either of the
IOLs IOLs IOLs optical axes IOLs - FIGS.1-3 illustrate one way that this invention may be embodied in IOLs. However, the invention may also be embodied in ophthalmic lenses which are adapted to be disposed on or in the cornea such as contact lenses and corneal inlays. The
lens bodies fixation members - This invention also provides a method of correcting the vision of a patient which comprises placing first and second multifocal ophthalmic lenses on or in the eyes of a patient with the first lens being distance biased and providing better visual acuity for objects at infinity than the second lens. The second lens is intermediate biased and provides better visual acuity from intermediate to near distances than the first lens. The maximum power of the second lens is less than the add power required for near vision correction for the patient. With specific reference to the embodiments shown in FIGS.1-3, the method includes implanting the
IOLs - With reference to FIG. 8, the
IOL 11 is implanted in ananterior chamber 47 of aneye 49 with thefixation members angle 51 of theiris 53. Theeye 49 has anatural lens 55 which has some residual accommodation and which has not been removed. Thus, theIOL 11 is to be used in conjunction with thenatural lens 55. TheIOL 13, which has optical characteristics different from theIOL 11, is similarly implanted in the other eye of the patient. - FIGS.6A-C are of use in gaining a further understanding of how the
IOLs IOLs - FIG. 6A shows the visual acuity with the distance eye, i.e., the eye in which the optimized distance to
intermediate IOL 11 is implanted. In a similar fashion, FIG. 6B shows the visual acuity in the intermediate eye, i.e., the eye in which the enhanced intermediate tonear IOL 13 is implanted, and FIG. 6C shows the binocular visual acuity, i.e., the visual acuity for both eyes with theIOLs - Because of the reduced add power in both of the
IOLs - FIGS.7A-C show the expected-through-focus-acuity for is an absolute presbyope with no accommodation using the
IOLs IOL 11 optimizes visual acuity from distance to intermediate distances as shown by the normal and functional visual acuity (FIG. 7A) from infinity to about 1.75 diopters of add power or about 57 centimeters. By comparing FIGS. 7A and 7B, it can be seen that theIOL 13 provides better visual acuity from intermediate to near distances than doesIOL 11 and that visual acuity in this range is enhanced. Also, by comparing FIGS. 7A and 7B, it can be seen that theIOL 13 provides better visual acuity for objects at near distances than theIOL 11. FIG. 7B shows that the best visual acuity provided by theIOL 13 is for objects at intermediate distances such as 67 cm which corresponds to 1.5 diopters of add power. - The binocular visual acuity remains functional or better for distance and intermediate objects. However, near reading between 40 centimeters and 33 centimeters becomes difficult. Thus, the absolute presbyope should perform all active tasks well including screening of mail. However, it is likely that about a 1 diopter to 1.5 diopter add power will be needed for extended near work. Nevertheless, the intermediate and near visual acuity for the absolute presbyope is significantly better than the equivalent presbyope without the
IOLs - It can be seen from FIG. 7B that the intermediate eye has no near vision peak, but only an intermediate peak at about 1.5 diopters or about 67 cm. Accordingly, the only way to increase the near image quality for the absolute presbyope is to increase the depth of focus of the intermediate peak to thereby increase the intermediate to near range of useable image quality.
- The depth of focus of the intermediate peak in FIG. 7B can be increased in two ways. First, the shape of the surfaces of the
zones - Secondly, in a simultaneous vision design the visual acuity for intermediate vision can be increased at the expense of distance image quality thereby raising the overall image quality and extending the depth of focus in the useable range of vision. This to some extent counters the decrease in intermediate visual quality associated with an increase in depth of focus by the introduction of optical aberration. The visual acuity for intermediate distances is increased by increasing the amount of light directed to the
intermediate zones - Although an exemplary embodiment of the invention has been shown and described, many changes, modifications, and substitutions may be made by one having ordinary skill in the art without necessarily departing from the spirit and scope of this invention.
