目的 观察不同截囊方式对白内障摘除人工晶体植入中 ,眼组织的损伤 ,术后后囊混浊的发生率的影响。方法 16 0例随机分为 2组 ,一组信封式截囊 ,一组改良信封式截囊 ,均进行前囊膜下水力分离皮质摘除白内障 ,植入人工晶体。结果 改良信封式截囊组术中囊袋完整率高 ,对眼组织损伤小 ,术后后囊膜混浊发生率低。结论 改良信封式截囊口弹性大 ,娩核时不撕破囊膜袋 ,手术成功率高。
Objective To observe the effects of different methods of capsulotomy on the implantation of intraocular lens (IOL), the damage of ocular tissue and the incidence of posterior capsule opacification in cataract extraction. [Methods] One hundred and sixteen cases were randomly divided into two groups. One group of enveloping capsulotomy and one group of modified enveloping capsulotomy were performed cataract extraction and cataract extraction with anterior subcapsular hydrocele. Results The modified enveloping capsulotomy group had a high intact rate of capsular bag, less damage to the ocular tissue and a lower incidence of posterior capsular opacification. Conclusion The modified envelope-type cyst capsis is flexible and does not tear the capsule when delivery. The success rate of operation is high.
