晚期囊袋内人工晶状体复合体脱位的研究进展

Research progress on late in-the-bag dislocation of intraocular lens complex

晚期囊袋内人工晶状体(intraocular lens,IOL)脱位是一种白内障术后少见但具有严重危害性的并发症。近年来随着人工晶状体眼的人群比例日益增加,眼科医生对这一并发症的关注和研究也逐步增多。研究表明,渐进性的悬韧带功能不全和晶状体囊袋收缩是其最可能的发病机制,高度近视、外伤和玻璃体切除术后是其发病的三大高危因素,对高危患者合理使用囊袋张力环是预防晚期囊袋内IOL脱位的较佳策略。

Late in-the-bag dislocation of intraocular lens complex is a rare complication but has server harmness.In recent years,as the proportion of intraocular lens in the population has increased,ophthalmologists are paying more and more attention to this complication and relevant studies are also gradually augmenting.A large number of studies have support that both progressive zonular dysfunction and contraction of the lens capsule are the most possible pathogenesis,and that high myopia,trauma and previous vitrectomy are the three high predisposing factors.Meantime,we can know that in order to prevent the complication,it’s a better way for the patients with high predisposing factors to use the capsular tensing ring.
