Surgical management of intraocular lens dislocations

ABSTRACTPurpose:To report and compare the surgical, visual, and anatomical outcomes following treatment of dislocated intraocular lenses (IOLs).Methods:The medical records of 28 eyes of 28 patients were evaluated. Age, gender, pre-and postoperative best-corrected visual acuity (BCVA), surgical methods, and complications were recorded.Results:Pre-and postoperative BCVA ranged from counting fingers to 20/32 and from counting fingers to 20/25, respectively. Late-onset dislocations were the most frequently observed complication. The most frequent surgical method was IOL repositioning in 15 of 28 patients, followed by IOL exchange in 11 patients, and IOL removal in 2 patients. Only 1 patient required surgical re-intervention with IOL capture.Conclusions:Visual acuity improved following the use of either IOL repositioning or IOL exchange. No superiority of one method over the other was observed. In the present retrospective case series, management of dislocated IOLs with repositioning or exchange of the primary implant conferred comparable surgical and visual outcomes.

摘要
研究目的：报道并比较脱位人工晶状体（intraocular lenses, IOL）治疗后的手术、视力及解剖学结局。
研究方法：回顾性分析28例患者共28只眼的临床病历资料，记录患者年龄、性别、术前及术后最佳矫正视力（best-corrected visual acuity, BCVA）、手术方式与并发症情况。
研究结果：术前最佳矫正视力范围为数指至20/32，术后则为数指至20/25。迟发性脱位为最常见的并发症。最常用的手术方式为人工晶状体复位术，28例患者中15例采用该术式，其次为人工晶状体置换术11例，人工晶状体取出术2例。仅1例患者需接受再次手术，行人工晶状体捕获固定术。
研究结论：采用人工晶状体复位术或置换术治疗后，患者视力均得到改善，未观察到两种术式间存在显著优劣差异。本回顾性病例系列研究显示，通过复位或置换原发人工晶状体的方式治疗脱位人工晶状体，可获得相近的手术及视力结局。
