Implantation of multifocal intraocular lenses using a magnification strategy in cataractous eyes with age-related macular degeneration

J Cataract Refract Surg. 2012 Mar;38(3):415-8. doi: 10.1016/j.jcrs.2011.12.022.

Abstract

Purpose: To examine visual function after targeting -2.0 diopter (D) spherical equivalent (SE) when implanting a multifocal intraocular lens (IOL) in eyes with cataract and age-related macular degeneration (AMD).

Setting: Three private practices.

Design: Case series.

Methods: Lenses of cataractous eyes with AMD were replaced with the Acrysof Restor SN60D3 multifocal IOL, targeting an SE of -2.0 D, which yielded +5.2 D near addition. Near and distance visual acuities were examined. Patients completed a visual function questionnaire preoperatively and 6 months postoperatively.

Results: At 6 months, 13 patients with 20 eligible eyes were examined. The uncorrected near visual acuity improved in 18 eyes (90%) and was unchanged in 2 eyes. The corrected distance visual acuity improved in 14 eyes (70%), was unchanged in 4 eyes (20%), and decreased (≤ 3 lines) in 2 eyes (10%). All vision-related questionnaire items improved.

Conclusion: For cataractous eyes with AMD, replacing the crystalline lens with this myopia-targeted multifocal IOL improved or maintained near vision without severely compromising distance vision.
