Analysis of Korean Retinal Specialists’ Opinions on Implanting Diffractive Multifocal Intraocular Lenses in Eyes with Underlying Retinal Diseases

Multifocal intraocular lenses (MF-IOLs) are increasingly implanted as the need for good near- and intermediate-distance vision increases. Although retinal disease is known to be a relative contraindication for MF-IOL implantation, there are no detailed guidelines for MF-IOL implantation with respect to the type and severity of retinal diseases/statuses. In this study, because retinal diseases can affect the performance of MF-IOLs, we analyzed the opinions of 111 retinal specialists, who were members of the Korean Retina Society, on the implantation of diffractive MF-IOLs in eyes with 15 retinal diseases/statuses using a web-based survey. For each underlying condition, retinal specialists were asked to rate their approval regarding implantation of MF-IOLs on a scale from 1 (completely disapprove) to 7 (completely approve), under the assumption that there were no known contraindications except for a given retinal disease/status. As a result, retinal specialists disapproved MF-IOL implantation (median value of Likert score < 4) in the eyes with wet age-related macular degeneration, dry age-related macular degeneration with geographic atrophy, proliferative diabetic retinopathy, nonproliferative diabetic retinopathy with macular edema, previous macula-off retinal detachment, previous retinal vein occlusion, and epiretinal membrane, but the scores varied by disease/status. The factors that affected the specialists’ opinions were the type of practice and the frequency of MF-IOL implantation (p = 0.013 and p = 0.021, respectively; one-way ANOVA).
