摘　　要：目的探讨吲哚青绿辅助下二次撕囊法在白色白内障超声乳化术中的安全性和可靠性。方法取29例30只眼，前房注入黏弹剂，将吲哚青绿（2．5mg／ml）均匀涂遍前囊膜。用撕囊针在前囊膜中央划开一个小瓣，伸入黏弹剂针头至囊膜下，抽出部分囊袋内乳化皮质，再用撕囊针撕出一个直径约为2mm左右的小囊口，抛光针头轻轻冲洗囊袋内皮质，往前房注入黏弹剂，剪开囊口，撕囊镊撕除一圈囊膜条，形成一个大小合适的囊口，常规行超声乳化吸除白内障。结果1只眼第一次撕囊后抛光针冲洗皮质时过分深人囊袋内，冲洗动作偏大，囊口右侧裂开，被及时发现，立即行第二次撕囊，囊口完整。其余29只眼均顺利完成二次撕囊，30只眼均囊袋内植入人工晶状体。结论吲哚青绿辅助二次撕囊法可以显著降低白色白内障撕囊的难度，使这种高危囊膜变得象普通囊膜一样易于操作和控制。Objective To examine the efficacy of two stage capsulorhexis assisted by indocya- nine green in cases of white cataract phacoemulsification. Methods Thirty eyes of 29 patients with white cataract were retrospectively reviewed. 0.25% indocyanine green was evenly spread on the anterior capsular membrane. After the anterior chamber was filled with viscoelastic, a small circular continuous capsuorhexis was made with needle, lrrigatoin was performed through the small capsulotomy to remove positive intralenticular pressure. A tangential cut on the left side of the capsulotomy was made with a scissors. The second continuous capsulotomy was accomplished with forceps. Results CCC was successfully accomplished in 30 eyes. In one eye, the first small continuous capsulotomy was rubbed off by excessively deep probing with the irrigation needle. The tear was found promptly and a second continuous capsulotomy was successfully performed with forceps. Conclusions Two stage capsulorhexis assisted with indocyanine green is effective in white cataract phacoemulsification.
