晚期囊袋人工晶状体复合体脱位的发病原因与危险因素分析

Late in-the-bag dislocation of IOL bag complex:Mechanisms in etiology and risk factors

晚期囊袋内人工晶状体复合体脱位是白内障术后较少见的一种潜在并发症,严重影响了患者的生活质量,通常需要手术处理。人们对这种并发症越来越关注,因为近年来有数量增长的趋势。该种术后并发症可能以较长时间周期呈现。有研究显示白内障手术和脱位之间的时间间隔为10.9 a,人工晶状体脱位的累积危险度在白内障摘出术后10a、20 a和25 a分别为0.1%、0.7%和1.7%。晚期囊袋内人工晶状体脱位是白内障术后多年的进展性小带裂开的结果 ,起源复杂而因素众多。本文将就晚期囊袋内人工晶状体脱位的发病情况、可能的病因机制与危险因素进行综述。

Late in-the-bag dislocation of intraocular lens bag complex is a rare but potential complication after cataract surgery, which can affect the quality of patients＇ life seriously, and usually need surgical treatment. People are paying more attention to this complication, because it has been reported with increasing frequency in recent years. This complication may present after a long time frame. There is a research show- ing that the interval between cataract surgery and the dislocation was 10.9 years. The cumulative risk of IOL dislocation at l0 years,20 years, and 25 years after cataract ex- traction was 0. 1% ,0.7% , and 1.7% respectively. Late in-the-bag IOL dislocation is a result of progressive zonular dehiscence up to many years after cataract surgery ,and its genesis is multifactorial. This article reviews the incidence ,possible mechanism and risk factors of late in-the-bag IOL dislocation.
