摘　　要：连续环形撕囊术 (continuous curvilinear capsulorhexis,CCC)是白内障超声乳化术的关键步骤之一。但在成熟或过熟白内障的眼中 ,由于晶状体呈白色混浊 ,手术显微镜同轴照明下缺乏视网膜红光反射作背景 ,囊膜结构难以看清 ,故难于实施 CCC。近来 ,一些学者利用不同的染色剂和染色技术成功地将晶状体前囊染色 ,从而为成熟或过熟白内障患眼施行 CCC展示了良好的应用前景。A continuous curvilinear capsulorhexis (CCC) of the anterior capsule is one of the critical steps in phacoemulsification procedure. But it is difficult to perform a CCC in the presence of mature or hypermature cataract because the red fundus reflex produced by the coaxial light of an operating microscope, which is necessary to observe the actual tearing process, is absent. Recently, various capsule dyes and techniques have been successfully used for staining the anterior capsule to allow a CCC to be safely performed in mature or hypermature cataract. So the anterior capsule staining may have good prospect.
