Visual Function after Multifocal Intraocular Lens Insertion in a Heterozygous Granular Corneal Dystrophy Type 2 Patient: Case Report

Purpose: A patient with heterozygous granular corneal dystrophy type 2 (GCD2) underwent phacoemulsification multifocal intraocular lens insertion, and complained of visual discomfort. We investigated the cause discomfort function in this case.Case summary: 59-year-old woman opacity had slit lamp photographs taken 5 years earlier. Two later, she (Trifocal AT Lisa tri toric 839MP<sup>®</sup>, Carl Zeiss Meditec AG, Inc., Jena, Germany) insertion both eyes at a local clinic. She felt very uncomfortable after surgery, but lattice opacities due to GCD2 her corneas remained stationary for years. Her acuity decreased from preoperatively (preoperative: right 0.5, left 0.6; last visit: 0.3, 0.4). contrast sensitivity was also total higher order aberration increased (right 1.590 μm, 1.194 μm), compared normal range.Conclusions: Multifocal cataract surgery can lead severe declines higher-order patient. It may not be advisable use lenses
