Abstract

Purpose: To evaluate the characteristics of and risk factors for spontaneous late in-the-bag intraocular lens (IOL) dislocation and to analyze the outcomes of surgical correction.

Setting: Department of Ophthalmology, Complejo Hospitalario Orense, Orense, Spain.

Methods: In this retrospective single-surgeon interventional case series, the surgical database of a referral center was searched for cases of late spontaneous in-the-bag IOL dislocation between 2005 and 2009. The main outcome measures were interval between surgery and dislocation, dislocation site and grade, IOL type, associated capsular tension ring (CTR), predisposing factors, surgical technique to correct dislocation, preoperative and postoperative corrected distance visual acuity (CDVA), and surgical complications.

Results: Pseudoexfoliation was the main risk factor for in-the-bag IOL dislocation (66.66% of 45 cases identified). A CTR was present in the capsular bag in 8 cases. Dislocation was corrected by repositioning using scleral fixation (20 cases) or iris suturing (1 case), IOL exchange for an anterior chamber IOL (AC IOL) (19 cases) or iris-claw IOL (4 cases), or (3) anterior capsulotomy (1 case). The mean CDVA improved significantly postoperatively (P = .0001); it was 20/40 or better in 28 eyes (62.22%) and 20/25 or better in 10 eyes (22.22%). There was no significant difference in postoperative CDVA between scleral-fixated IOLs and AC IOLs (P = .316).

Conclusions: Pseudoexfoliation was the main risk factor for in-the-bag IOL dislocation. The presence of a CTR in the bag did not prevent dislocation. Satisfactory results were achieved with a low rate of complications using different surgical techniques to correct IOL position.
