摘　　要：连续弧线形撕囊（ＣｏｎｔｉｎｕｏｕｓｃｕｒｖｉｌｉｎｅａｌｃａｐｓｕｌｏｒｈｅｘｉｓＣ．Ｃ．Ｃ．）是白内障超声乳化术中一个重要的步骤，它提供一个边缘光滑的前囊膜环形开口，确保了晶体悬韧带及周边囊膜的完整。本文统计分析６００眼Ｃ．Ｃ．Ｃ．成败结果及原因，并介绍了手术技巧。共成功５１８眼，占８６．３３％，认为失败的主要原因是白内障皮质乳化膨胀引起前囊膜表面张力增高及调整和控制撕囊时的用力方向不当，作者体会到成功的关键是：①充分散瞳，②保持前房深度，③降低前囊膜的表面张力，④使用精良的撕囊器械，⑤选择正确的撕囊起点，⑥适时调整和控制撕囊时的用力方向，⑦控制撕囊的大小、速度和撕开方向。ontinuous curvilineal capsulorhexis(C C C )is a very important step in the phaco.Through that step,a smooth round openning on the anterior capsule is made and an intact zonular ligment and peripheral anterior capsule will be obtained.Thus the phaco and the implantation of the IOL in the capsular bag will be accomplished successfully. In this paper 600 eyes C C C were reported.The techniques of C C C were discussed in detail and the effects were analized.The main causes of successful cases are:1)dilating the pupil thoroughly;2)keeping a deep chamber;3)decreasing the tension of anterior capsule;4)using the proper instrument;5)beginning with a proper incision;6)adjusting a correct direction of the tearing force;7)controling the speed of the manoeuvre;8)linking the tearing point(starting and ending) correctly.
