A 76-year-old woman had sudden visual loss 9 years after an extracapsular cataract extraction with implantation of a poly(methyl methacrylate) disc intraocular lens (IOL) in the capsular bag. Slitlamp examination showed the disc IOL had luxated into the vitreous through a linear inferior opening in the capsular bag; the IOL lay on the retinal surface. A pars plana vitrectomy was performed. The vitreous cavity was filled with perfluorocarbon liquid, floating the IOL to behind the iris. The IOL was removed through a limbal incision, then another type of IOL was implanted in the ciliary sulcus using transscleral fixation. Thirty days after surgery, best corrected visual acuity (BCVA) was 20/20. At 2 months, total retinal detachment appeared with a large superior retinal dialysis. Another pars plana vitrectomy was performed and the scleral-fixated IOL removed through a limbal incision. Internal gas tamponade was used. The eye was left aphakic. Final BCVA was 20/25.
一名76岁女性在行囊外白内障摘除并在囊袋内植入聚甲基丙烯酸甲酯盘状人工晶状体（IOL）9年后突然视力丧失。裂隙灯检查显示盘状IOL通过囊袋下方的线性开口脱位至玻璃体；IOL位于视网膜表面。行玻璃体切除术。玻璃体腔内填充全氟碳液体，将IOL漂浮至虹膜后方。通过角膜缘切口取出IOL，然后使用经巩膜固定法在睫状沟植入另一种类型的IOL。术后30天，最佳矫正视力（BCVA）为20/20。2个月时，出现视网膜全脱离并伴有大片上方视网膜脱离。再次行玻璃体切除术，并通过角膜缘切口取出巩膜固定的IOL。使用眼内气体填充。该眼最终呈无晶状体状态。最终BCVA为20/25。
