Changes of corneal thickness and endothelial ultrastructure of rabbit eyes after radial keratotomy as well as effects of prednisolone and bendazac-lysine on keratectomized corneas were studied. The corneal thickness increased after keratotomy and the maximum values of control eyes were measured on the seventh day postoperatively; they returned to normal after 2 months. Swelling of mitochondria, disappearance of cristae, increased synthetic activity, and elaboration of cell junction were found with electron microscope. We conclude that direct trauma or postoperative inflammation plays a minor role in the pathogenesis of endothelial alterations, while elaboration of free radicals during normal regenerating processes may be a principal cause of endothelial changes. Prednisolone treatment was ineffective in preventing the development of corneal edema and endothelial alterations. Bendazac-lysine treatment decreased both corneal edema and endothelial changes.

Abstract

Changes of corneal thickness and endothelial ultrastructure of rabbit eyes after radial keratotomy as well as effects of prednisolone and bendazac-lysine on keratectomized corneas were studied. The corneal thickness increased after keratotomy and the maximum values of control eyes were measured on the seventh day postoperatively; they returned to normal after 2 months. Swelling of mitochondria, disappearance of cristae, increased synthetic activity, and elaboration of cell junction were found with electron microscope. We conclude that direct trauma or postoperative inflammation plays a minor role in the pathogenesis of endothelial alterations, while elaboration of free radicals during normal regenerating processes may be a principal cause of endothelial changes. Prednisolone treatment was ineffective in preventing the development of corneal edema and endothelial alterations. Bendazac-lysine treatment decreased both corneal edema and endothelial changes.
