Visual outcomes and patient satisfaction in 9366 eyes using a refractive segmented multifocal intraocular lens

Abstract

PURPOSE: To report the effectiveness, patient satisfaction, and complication rate with a zonal refractive intraocular lens (IOL) in a high volume of patients. SETTING: Private clinic, London, United Kingdom. DESIGN: Case series. METHODS: Retrospective data of patients with binocular Lentis Mplus IOLs were analyzed. The main outcome measures were uncorrected distance visual acuity (UDVA), uncorrected near visual acuity (UNVA), corrected distance visual acuity, manifest refraction, patient satisfaction, and complications. One-month, 3-month, and 6-month data were analyzed. RESULTS: The study comprised 9366 eyes of 4683 patients. The mean spherical equivalent changed from +1.73 diopters (D) ± 3.37 (SD) preoperatively to -0.02 ± 0.60 D at 3 months and +0.03 ± 0.60 D at 6 months. Ninety-five percent of patients achieved a binocular UDVA of 6/7.5 (0.1 logMAR) or better 3 months postoperatively. The mean binocular UNVA was 0.155 ± 0.144 logMAR and 0.159 ± 0.143 logMAR at 3 months and 6 months, respectively. Severe dysphotopsia requiring an IOL exchange occurred in 55 eyes. Patient satisfaction was high, with 97.5% of patients willing to recommend the procedure. CONCLUSIONS: The zonal refractive IOL provided excellent distance and near visual acuity. The postoperative complication rate was clinically acceptable, and patient satisfaction high. FINANCIAL DISCLOSURE: Dr. Schallhorn is a consultant to Abbott Medical Optics, Inc.
