Clinical data of 427 cases (458 eyes) of extracapsular cataract extraction and IOL implantation gave the impression that vitreous prolapse due to disruption of the zonula and the posterior capsule was a malpractical complication. Forcible capsulotomy too large or deep and uneven irrigating pressure were the common causes of zonular disruption. Obstructed passage and insufficient separation of the nucleus from the posterior cortical bed leading to difficult nuclear delivery, aspiration of cortex in the posterior chamber, poorly filled anterior chamber, insufficient room for the IOL, improper insertion of the posterior haptics and traumatic dialing were risk factors for posterior capsular rupture and vitreous prolapse.
427例（458眼）白内障囊外摘除联合人工晶状体植入术的临床资料显示，因悬韧带和后囊破裂导致的玻璃体脱出是一种较难处理的并发症。强行进行过大或过深且不均匀的灌洗压力的截囊是悬韧带断裂的常见原因。通道受阻、核与后皮质床分离不充分导致核娩出困难、后房皮质抽吸、前房填充不良、人工晶状体空间不足、后襻插入不当以及外伤性拨核是后囊破裂和玻璃体脱出的危险因素。
