白色白内障撕囊丢失囊膜台盼蓝染色的有效性探讨

目的 探讨成熟期和过熟期白色白内障连续环形撕囊(CCC)囊膜丢失后,在不吸除黏弹剂情况下使用台盼蓝染色找回丢失囊膜的有效性.方法 对52例(52只眼)术中连续环形撕囊发生囊膜丢失的连续性白色白内障病例进行前瞻性研究.随机分为两组,染色组27例(27只眼),对照组25例(25只眼).染色组不吸除前房玻璃酸钠,使用台盼蓝囊膜染色.对照组吸除前房玻璃酸钠后进行撕囊或截囊.对两组连续环性撕囊成功率、人工晶状体囊袋内植入率进行统计学分析.结果 染色组连续环形撕囊及人工晶状体囊袋内植入率高于对照组,差异具有统计学意义(P<0.01),无毒性及并发症发生.对照组有9只眼人工晶状体植入睫状沟,6只眼发生后囊膜破裂及玻璃体脱出.结论 在连续环形撕囊发生囊膜丢失后,采取不吸除前房黏弹剂,应用台盼蓝对晶状体前囊膜染色,对找回丢失囊膜和CCC继续完成是有效和安全的.

Explore the efficacy of Trypan blue capsular staining to find a lost edge of capsulorthexis in white cataracts

Objective To explore the efficacy of trypan blue to find a lost edge of a continuous curvi-linear capsulorthexis (CCC)in white cataracts without removing Sodium Hyaluronate in anterior chamber. Methods Prospective observational study on consecutive eyes of 52 patients with white cataract who had "loss" of CCC.52 patients were randomly divided into two groups.In Group A (trypan blue),27 eyes of 27 pa-tients, trypan blue were applied to visualize the lost edges of CCC without removing Sodium Hyaluronate in an-terior chamber.In Group B (control group), 25 eyes of 25 patients, capsulorhexis or anterior capsulatomy was performed after removing Sodium Hyaluronate.The rates of complete capsuiorrhexis and IOL implanted in bag were compared between the groups.Results The rates of complete capsulorrhexis and IOL implanted in bag in Group A were all higher than in Group B (P<0.01).No toxic or complications were observed in Group A.In Group B, IOLs of 9 eyes were implanted in ciliary grooves.Postcapsule ruptures and prolapses of vitreous of 6 eyes occured.Conelusions It is effective and safe to apply Trypan blue to find the lost edge of CCC and con-tinue it without removing Sodium Hyaluronate in anterior chamber after loss of capsulorhexis during surgery.
