白内障手术并发大泡性角膜病变临床分析

目的：探讨白内障手术并发大泡性角膜病变的原因、处理及预防措施。方法：1993年5月-2001年12月在我院实施白内障摘除人工晶状体植入术556例，对其中并发大泡性角膜病变11例患者的情况进行回顾性分析。结果：本组共发生大泡性角膜病变11例，占白内障手术患者的1.9％，其中巩膜隧道切口非超声乳化白内障摘除及人工晶状体入术组发生率最高。结论：进出前房的液体或药物对角膜内皮的化学性损伤是引起大泡性角膜病变的主要原因。避免发生大泡性角膜病变重在预防。

Clinical analysis of bullous keratopathy after cataract surgery

Objective:To investigate the causes,management and prevention of bullous keratopathy after cataract surgery.Methods:From May 1993 to December 2001,556 patients were performed cataract extraction and intraocular lens implantation at the 405th Hospital,and there were 11 patients developed bullous keratopathy postoperatively.Results:The deta of these 11 patients were reviewed retrospectively.The rate of occurrence was 1.9%.Incidence rate was highest in patients who had non-phacoemulsification combined intraocular lens implantation through scleral tunnel incision.Conclusions:The chemical trauma to the cornea endothelium caused by the fluid and medicine that passing through the anterior chamber is the predominant factor predisposing to bullous keratopathy.Bullous keratopathy may be prevented,if the operator takes care in every step during operation.
