Dislocation of an intraocular lens (IOL) with the capsular bag is a late complication of cataract surgery, reported with increasing frequency in recent years. Pseudoexfoliation, uveitis, myopia, and other diseases associated with progressive zonular weakening and capsular contraction are the predisposing conditions. Capsular tension rings probably help but do not prevent this complication. Management includes IOL exchange, replacement with an anterior or a sutured posterior chamber IOL, or suturing the IOL through the bag to the iris or the sclera.
人工晶状体（IOL）与囊袋脱位是白内障手术的一种晚期并发症，近年来报告的频率越来越高。假性剥脱、葡萄膜炎、近视以及其他与进行性悬韧带松弛和囊袋收缩相关的疾病是诱发因素。囊袋张力环可能有帮助，但不能预防这种并发症。处理方法包括更换人工晶状体、用前房型或缝合固定的后房型人工晶状体进行置换，或将人工晶状体通过囊袋缝合至虹膜或巩膜。
