Posterior capsular rupture is a common complication of cataract extraction surgery. Prompt management of anterior and posterior capsular tears may prevent associated complications or need for subsequent procedural intervention.
When tears develop in the anterior capsule, novel techniques allow predictable rescue of a capsulorhexis, preventing radial extension to the posterior capsule. Several case series now describe techniques and outcomes of posterior assisted levitation techniques for a dislocated nucleus. Triamcinolone staining of the vitreous improves visualization and removal of vitreous in the anterior segment following capsular rupture. Recently published studies further describe the increased risks of endophthalmitis and retinal detachment following capsular tears.
Several techniques may prove beneficial in the intraoperative management of an anterior capsular tear, a dislocated nucleus, or vitreous loss.
后囊膜破裂是白内障摘除手术的常见并发症。及时处理前后囊膜撕裂可预防相关并发症或避免后续进行手术干预的必要性。
当前囊膜出现撕裂时，新技术能够可预测性地挽救连续环形撕囊，防止放射状延伸至后囊膜。多个病例系列现已描述了用于脱位晶状体核的后辅助悬浮技术的操作技巧及效果。囊膜破裂后，玻璃体的曲安奈德染色可改善前段玻璃体的可视化及清除效果。最近发表的研究进一步描述了囊膜撕裂后眼内炎和视网膜脱离风险的增加。
在术中处理前囊膜撕裂、晶状体核脱位或玻璃体丢失时，有几种技术可能会被证明是有益的。
