Visual performance and photic disturbances with diffractive and nondiffractive EDOF intraocular lenses using mini-monovision: randomized trial

Abstract

Purpose: To compare visual performance and photic visual disturbances of patients implanted with 2 different extended depth-of-focus (EDOF) intraocular lenses (IOLs) using mini-monovision. Setting: Ambulatory surgical center at the University of São Paulo in Ribeirão Preto, Brazil. Design: Prospective, examiner-masked, randomized clinical trial. Methods: Patients were assigned to either a bilateral Symfony (SYM) or Vivity (VIV) IOL group, with 1 eye targeted for myopia (−0.75 diopter [D]). Defocus curve, contrast sensitivity (Pelli-Robson), Patient-Reported Spectacle Independence Questionnaire, and Quality of Vision questionnaire were recorded at 3 months postoperatively. Results: A total of 126 patients finished the follow-up: group SYM: n = 60 and group VIV: n = 66. Regarding near visual acuity, 80% of patients in the SYM group and 84% of patients in the VIV group achieved J2 or better on the near-planned eye (P = .3840). No significant differences were found between groups for distance visual acuity, defocus profiles, PRISC, contrast sensitivity, or reading speed (P > .05). Notably, significant between-group differences were observed for bothersome visual disturbances (P = .0235), with 45% of patients in the SYM group with a score of 0 for bothersome disturbances compared with 66% in the VIV group. Conclusions: Mini-monovision using these EDOF IOLs was well-tolerated in the patient cohort. No significant differences were found for visual performance tests between the VIV and SYM groups. However, the data suggest that Vivity IOL is associated with a lower probability of bothersome visual disturbances compared with Symfony IOL.
