Outcome of sulcus fixation of dislocated posterior chamber intraocular lenses using temporary externalization of the haptics.

Abstract

This study evaluated the visual outcome and complications of repositioning and sulcus fixation of a dislocated posterior chamber intraocular lens (PC IOL) using a technique in which the haptics of the IOL are temporarily externalized for suture placement. Retrospective, noncomparative case series. Seventy-eight patients with a dislocated PC IOL. All patients underwent surgery to fixate the PC IOL using this technique. Patients were evaluated for visual acuity, refractive error, and surgical complications associated with the procedure. The average visual acuity before surgery was 20/205 (range, 20/20 to light perception), with a median refractive error of -1.00 diopters (D; range, -7.25-+15.00 D). After surgery, the average visual acuity improved to 20/72 (range, 20/20 to no light perception), with a median refractive error of -0.75 D (range, -5.50-+3.50 D). Patients were observed for a median of 15.5 months (range, 6-57 months). Twenty patients had postoperative cystoid macular edema (26%), 7 patients had an epiretinal membrane (ERM) (9%), and 5 patients had a retinal detachment (6%). Eight patients (10%) experienced iris capture of the sutured IOL, and in three patients (4%) the PC IOL dislocated again after surgery. This technique is an effective method for securing a dislocated PC IOL.
