Abstract Details

Purpose:

To compare the presentation characteristics and surgical outcomes of late in- the-bag IOL dislocation between cases with and without capsular tension ring (CTR) within the capsular bag.

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 measure was the number of cases with CTR within the capsular bag. The following data were recorded and compared between the group with and without CTR: age, interval between surgery and dislocation, dislocation site/grade, type of IOL, predisposing factors, surgical technique used to correct dislocation (repositioning using scleral fixation, iris suturing, IOL exchange for anterior chamber IOL, or iris–claw IOL, IOL removal and anterior capsulotomy), preoperative/postoperative corrected distance visual acuity (CDVA) and intraocular pressure (IOP), and surgical complications.

Results:

171 cases were identified, 33 of which had a CTR within the bag. Regarding presentation characteristics, no significant difference was found between the groups with and without CTR, except in the time between original surgery and dislocation which was significantly shorter in the group with CTR (70.76 ± 28.77 vs 107.45 ±39.35 months, p=0.000). No significant difference was found in the type of surgery selected to correct IOL position (p=0.564). Mean CDVA improved significantly and mean IOP decreased significantly after surgery (p=0.000). There was no significant difference in postoperative CDVA or IOP between the group with or without CTR.

Conclusions:

In the largest series of cases of in-the-bag CTR-IOL dislocation reported to date, a CTR within the bag not only did not prevent dislocation but it occurred significantly earlier. Satisfactory results were achieved, without any significant difference between the groups with and without CTR.
