Implantation of a myopia-targeted multifocal IOL improved or maintained near vision without significantly diminishing distance vision in cataractous eyes with concomitant age-related macular degeneration, according to a study.
“The preliminary results in this study suggest this multifocal-magnification strategy holds promise for visual rehabilitation of AMD patients with cataract and may be useful in guiding researchers and manufacturers in the design of high-magnification IOLs for AMD patients,” the study authors said.
The analysis included 20 eyes of 13 patients with concurrent cataract and dry AMD or AMD associated with disciform scarring. All eyes received an AcrySof ReSTOR SN60D3 spherical multifocal IOL (Alcon).
Visual and refractive outcomes were evaluated at 1 week, 4 weeks and 6 months. The Visual Function Questionnaire (VFQ-25) was administered at 6 months.
Study results showed that uncorrected near visual acuity improved in 18 eyes and was unchanged in two eyes. Improvements were one to three lines in 10 eyes, four to seven lines in four eyes and more than seven lines in four eyes. No eyes lost lines of uncorrected near visual acuity.
Corrected near visual acuity improved in 17 eyes, was unchanged in one eye and diminished in two eyes.
Uncorrected distance visual acuity improved one to three lines in four eyes, was unchanged in eight eyes and decreased in eight eyes.
Patients reported significant improvement in general vision, mental health symptoms tied to vision, role difficulties linked to vision, limitations with peripheral vision and overall scores (P < .05), the authors said.
