The experiences of the management of 20 cases (20 eyes) of intraocular lens (IOL) dislocation or subluxation were summarized in this report. All the patients underwent primary extracapsular cataract extraction with posterior chamber IOL implantation. The dislocation or subluxation occurred in 2 eyes intraoperatively and 18 eyes in 1 day to 3 years, post-operatively. The IOLs were captured at pupils in 12 eyes, dislocated into the vitreous in 4 eyes, represented as in westeast syndrome in 2 eyes and sunset and sunrise syndrome in 1 eye and 1 eye, respectively. Of the 20 eyes, 1 eye with mild sunset syndrome was treated with a miotic, 2 eyes with IOL pupillary capture were treated successfully by conservative therapy and the rest, by surgeries. In cases treated by operations, the IOLs were removed from original incisions in 3 eyes, by vitrectomies in 5 eyes and surgical reposition of IOLs were undertaken in 9 eyes with IOL pupillary capture of which 7 eyes were successful and in 2 eyes recurrence took place shortly after reposition. The causes and management of IOL dislocation or subluxation were discussed.
本报告总结了20例（20眼）人工晶状体（IOL）脱位或半脱位的处理经验。所有患者均接受了白内障囊外摘除联合后房型人工晶状体植入术。术中发生脱位或半脱位2眼，术后1天至3年发生18眼。人工晶状体位于瞳孔区12眼，脱入玻璃体腔4眼，呈西-东综合征2眼，分别呈日落综合征和日出综合征各1眼。20眼中，1眼轻度日落综合征患者采用缩瞳剂治疗，2眼人工晶状体瞳孔夹持患者保守治疗成功，其余患者均行手术治疗。手术治疗的病例中，3眼经原切口取出人工晶状体，5眼行玻璃体切除术，9眼人工晶状体瞳孔夹持患者行人工晶状体手术复位，其中7眼成功，2眼复位后不久复发。文中讨论了人工晶状体脱位或半脱位的原因及处理方法。
