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

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.
