Visual outcome and optical quality after implantation of zonal refractive multifocal and extended-range-of-vision IOLs: A prospective comparison

Abstract

Purpose:To compare the visual outcomes and optical quality of 2 presbyopia-correcting intraocular lenses (IOLs) with those of a monofocal IOL.Settings:Eye Center, the Second Affiliated Hospital of Zhejiang University, School of Medicine, Hangzhou, Zhejiang, China.Design:Prospective cohort study.Methods:The study included patients who had cataract surgery and were implanted with a Tecnis Symfony Extended Range of Vision (EROV) IOL (ZXR00), a zonal refractive multifocal IOL (Lentis Comfort LS-313 MF15), or a monofocal IOL (Lentis L-313). Postoperative examinations took place at 1 week, 1 month, and 3 months and included visual acuity at far, intermediate, and near distances, defocus curves, contrast sensitivity, wavefront aberrations, and modulation transfer function (MTF). Patients completed the Visual Function Index questionnaire (VF-14), the Quality of Vision questionnaire (QoV), and a visual quality self-evaluation.Results:One hundred thirteen patients were enrolled. The EROV and multifocal IOLs achieved a significantly better range of intermediate vergences (P
