Small-incision iris fixation of foldable intraocular lenses in the absence of capsule support

Ophthalmology. 2007 Jul;114(7):1311-8. doi: 10.1016/j.ophtha.2007.04.018.

Abstract

Purpose: To report visual outcomes and complications of modified McCannel iris suture fixation of small-incision foldable acrylic intraocular lenses (IOLs) for aphakia in the absence of capsule support.

Design: Retrospective interventional case series.

Participants: Forty-six patients who underwent foldable acrylic IOL implantation using peripheral iris suture fixation for aphakia in the absence of capsule support.

Methods: Data from 46 patients who underwent iris fixation of a foldable acrylic IOL were retrospectively evaluated for underlying diagnoses, surgical history, clinical results, and complications.

Main outcome measures: Postoperative best-corrected visual acuity (BCVA), spherical equivalent, and surgical complications.

Results: Best-corrected visual acuity improved from 20/100 to 20/50 (P = 0.01), with 97% of eyes maintaining or improving BCVA after a mean (+/- standard deviation) follow-up of 24.1+/-12.4 months. Complications included transient low-grade uveitis (3 [6.5%]), transient pigment dispersion (3 [6.5%]), IOL dislocation (2 [4.3%]), elevated intraocular pressure (1 [2.2%]), and retinal detachment (1 [2.2%]). No new cases of cystoid macular edema or worsening of glaucoma occurred.

Conclusion: Small-incision peripheral iris fixation of 3-piece acrylic foldable IOLs in the absence of capsule support appears to be an effective technique with few severe adverse events.
