普通型囊袋张力环在中重度晶状体半脱位手术中的应用

The Application of Capsular Tension Ring for Moderate-Severe Lens Subluxation During Surgery

目的探讨普通型囊袋张力环在晶状体中重度脱位白内障手术中的应用价值。方法对11例（11眼）白内障并伴有135°~225°晶状体脱位患者行白内障手术,其中6例（6眼）玻璃体脱出前房者先行前部玻璃体切除后环形撕囊;将囊袋张力环两端孔穿过聚丙烯缝线固定于脱位侧巩膜上,白内障超声乳化吸出后植入折叠式人工晶状体。结果术后随访3～24个月,最佳矫正视力0.6～1.0者4眼（36.4%）,0.3～0.5者6眼（54.5%）,〈0.3者1眼（9.09%）。UBM提示所有的人工晶状体均正位无偏斜。结论对于晶状体大范围脱位者应用缝线固定普通型囊袋张力环有利于囊袋完整及人工晶状体植入,防止人工晶状体偏位,获得良好的视力恢复。

Objective To evaluate the safety and efficiency of Capsular tension ring（CTR） for the treatment of moderate to severe lens subluxation during phacoemuleification. Methods This prospective Study included 11 eyes of 11 Patients with cataract and moderate -severe lens subluxation, For 3 cases which vitreous body came out into anterior chamber we performed anterior vitrectomy first .All cases were performed cataract surgery, sutured The CTR on the sclera, aspirated the cortes, then implanted the intraocular lens into the capsule.Results The follow-up period range from 3 to 24 months, BCVA 0.6-1.0 on four eyes（36.4%）, 03-0.5 on six eyes（54.5%）, 〈0.3 on only one eye （9.1%）. UBM showed no IOL was found to be decentrated at the end of the follow-up period .Conclusion CTR is useful in the cataract Surgery in cases with moderate -severe lens subluxation, it helps to keep the capsule integral, prevent the intraocular lens deviate, and gain good vision for the patients.
