Abstract
The invention relates to a method of testing the local toxicity of a substance, characterized in that a cornea of an animal is exposed to the substance and the change in the corneal thickness is measured, and optionally also the change in the corneal light absorption or light transmission properties is measured. The change in the cornea thickness can be measured by a pachymeter, the change in the corneal absorption or transmission properties can be measured pectrophotometrically. The invention further relates to an insert to a cuvette for the spectrophotometric measurement. ˙
