目的.探讨中国汉族人群人工晶状体植入术后人工透镜（IOL）脱位的临床特点。方法.回顾性分析了2007年1月至2017年12月期间人工晶状体脱位患者的病历，本研究共纳入312例患者（男性：231例，女性：97例）（328只眼）。记录眼轴长度（AL）、人工晶状体度数、白内障手术至人工晶状体脱位的时间间隔以及人工晶状体脱位相关的眼部情况。根据人工晶状体脱位与晶状体囊的关系及脱位人工晶状体的位置对人工晶状体脱位进行分类和分级。结果初次白内障手术与IOL脱位之间的平均时间为5.63 +/- 5.13年; 5年内发生IOL脱位的患眼高达56.1%（184只眼）。外伤136眼（41.5%），玻璃体切除术61眼（18.6%），高度近视108眼（32.9%）。共有243只眼（74.1%）发生囊外IOL脱位，85只眼（25.9%）发生囊内IOL脱位。袋内脱位与袋外脱位的创伤构成比差异有统计学意义（Pearson's chi（2）= 33.3992，P
Purpose. To investigate the clinical characteristics of patients with intraocular lens (IOL) dislocation after IOL implantation in Chinese Han populations. Methods. The medical records of patients with IOL dislocation were retrospectively reviewed from January 2007 to December 2017, and a total of 312 patients (male: 231, female: 97) (328 eyes) were included in this study. The axial length (AL), IOL power, and the time interval between cataract surgery and IOL dislocation as well as the ocular conditions associated with IOL dislocation were recorded. The IOL dislocation was classified and graded based on its relationship with the capsule and the position of the dislocated IOL. Results. The mean time between original cataract surgery and IOL dislocation was 5.63 +/- 5.13 years; IOL dislocation occurred in up to 56.1% (184 eyes) of the eyes within 5 years. Trauma was found in 136 eyes (41.5%); pars plana vitrectomies were performed in 61 eyes (18.6%), and high myopia was detected in 108 eyes (32.9%). A total of 243 eyes (74.1%) had out-of-the-bag IOL dislocations, while 85 eyes (25.9%) had in-the-bag IOL dislocations. There was a statistically significant difference in the constituent ratio of trauma between in-the-bag dislocation and out-of-the-bag dislocation (Pearson's chi(2) = 33.3992, P
