Iatrogenic endothelial damage during cataract extraction.

Morphological changes in the endothelium of rabbits' corneas after rinsing with Ringer's solution, chymytrase 0.05% or acetylcholine could not be demonstrated by vital staining with nitroblue tetrazolium. Local lesions caused by manipulations in the anterior chamber were conspicuous. Endothelial lesions due to manipulations with an intra-ocular lens were studied in the same way.
