现代囊外白内障摘除术中后囊破裂的临床分析

目的 探讨现代囊外白内障摘除术中后囊破裂玻璃体脱出的原因、处理方法、人工晶状体的植入及如何避免并发症以提高手术效果。方法 对1570眼现代囊外白内障摘除术中后囊破裂玻璃体脱出病例作回顾性研究。结果 术中晶状体后囊破裂185眼(占11.78％)、并发玻璃体脱出121眼(7.71％);术后早期(1周内)视力平均0.5。结论 后囊破裂可以出现在白内障超声乳化手术中的各个手术步骤,术中重视预防;及早发现后囊破裂并给予适当处理,准确判断后囊破裂的大小和方位,恰当利用残留的前后囊膜,正确处理脱出的玻璃体,一期植入后房型人工晶状体仍可获得较好的效果。

Clinical analysis of posterior capsular rupture in extracapsular cataract extraction

Objective To discuss the causes and management of posterior capsular rupture with vitreous prolapse during extracapsular cataract extraction (ECCE), as well as artificial lens implantation in this context. Methods A retrospective study was made of 1570 eyes having received ECCE. Results Posterior capsular rupture occurred to 185 eyes (11.83%), accompanied by vitreous prolapse in 121 eyes (7.71%). The mean vision, 1 week postoperatively, was 0.5. Conclusion Posterior capsular rupture can occur in any step of ECCE. In order to prevent complications and achieve good ECCE effect, it is critical to realize and manage the rupture as early as possible, to determine its size and running, to use the remnant anterior and posterior capsular membrane appropriately and to manage vitreous prolapse correctly.
