Abstract Details

Purpose:

To evaluate the presentation characteristics and surgical outcomes after the correction of late in-the-bag IOL dislocation.

Setting:

Complexo Hospitalario Universitario Ourense, Ourense and Complexo Hospitalario Universitario A Coruña, A Coruña, Spain.

Methods:

Retrospective interventional case series including cases of late spontaneous in-the-bag IOL dislocation from two referral centers. The main outcome measures were interval between surgery and dislocation, dislocation site/grade, type of IOL, associated CTR, predisposing factors, surgical technique used to correct dislocation (repositioning using scleral fixation (SFIOL), iris suturing, IOL exchange for anterior chamber IOL (ACIOL), or iris–claw IOL (ICIOL), IOL removal and anterior capsulotomy), preoperative/postoperative corrected distance visual acuity (CDVA) and intraocular pressure (IOP), and surgical complications.

Results:

171 cases of in-the-bag IOL dislocation were identified. Pseudoexfoliation was the most common risk factor (78.9%). Mean interval between cataract surgery and surgical correction was 100.62±40.17 months. Dislocation was corrected: 1) repositioning using SFIOL (73 cases) or iris suturing (1 case); 2) IOL exchange ACIOL (38 cases) or ICIOL (30 cases); 3) IOL removal (4 cases); 4) capsulotomy (3 cases). Twenty-two patients refused surgery. Mean CDVA improved significantly after surgery (p=0.000). There was no significant difference in postoperative CDVA between SFIOL, ACIOL and ICIOL (p=0.719). Surgical complications were rare.

Conclusions:

In the largest series of cases of in-the-bag IOL dislocation reported to date, pseudoexfoliation was the main risk factor and satisfactory results were achieved with a low rate of complications using different surgical alternatives to correct IOL position.
