Abstract
Purpose: To evaluate the proportions of corneal endothelial lesion caused by differentfactors during phacoemulsification and aspiration.Methods: Fourteen cats (twenty eight eyes) were divided into four groups. The processedfactors were ultrasonic power, lens extraction by phacoemulsification or not, and lensextraction using different levels of ultrasonic power. The density of central cornealendothelial cells was measured before and after operation.Results: There is no statistic difference between pre-operation density and post-operationdensity for releasing ultrasonic power only without lens extraction group. But for the lensextraction group, there is difference in density of central corneal endothelial cells andthe higher level of ultrasonic power, the more the central corneal endothelial cells densitydecreased through operation.Conclusion: The primary factor that causes corneal endothelial lesion duringphacoemulsification and aspiration procedure is debris of lens nucleus, and the otherfactors cause the lesion of corneal endothelium in normal operations just in very smalldegree.关键词
