Comparison of long-term visual outcome and IOL position with a single-optic accommodating IOL After 5.5- or 6.0-mm Femtosecond laser capsulotomy

Abstract

Purpose: To evaluate the long-term visual outcome and intraocular (IOL) position parameters with a single-optic accommodating IOL after 5.5- or 6.0-mm femtosecond laser capsulotomy.

Methods: This prospective, randomized, pilot study comprised 17 eyes from 11 patients (7 men) with a mean age of 65.82±10.64 years (range: 51 to 79 years). All patients received a Crystalens AT-50AO (Bausch & Lomb) accommodating IOL after femtosecond laser refractive cataract surgery using either a 5.5-mm capsulotomy (5.5-mm group; 9 eyes) or 6.0-mm capsulotomy (6.0-mm group; 8 eyes). Near and distance visual acuities, manifest refraction spherical equivalent (MRSE), and IOL tilt and decentration were evaluated 1 year postoperatively.

Results: No significant differences were noted between groups for postoperative uncorrected distance visual acuity, uncorrected near visual acuity, distance-corrected near visual acuity, and MRSE. Vertical and horizontal tilt were significantly higher in the 6.0-mm group than in the 5.5-mm group (P=.014 and P=.015, respectively). No significant difference was observed between groups regarding IOL decentration.

Conclusions: A 5.5-mm capsulotomy created with a femtosecond laser is associated with less IOL tilt and therefore may be superior to a 6.0-mm capsulotomy when implanting a single-optic accommodating IOL.
