Visual disturbances produced after the implantation of 3 EDOF intraocular lenses vs 1 monofocal intraocular lens

The diffractive extended depth-of-focus IOL models examined induce similar dysphotopsic disturbances, which are nevertheless worse than those produced by the nondiffractive extended-range model and the monofocal one. Purpose: To compare the visual disturbances experienced by patients receiving 1 of 3 extended depth-of-focus (EDOF) intraocular lenses (IOLs) or a monofocal IOL as the control. Setting: OMIQ-Recerca Center. Spain. Design: Prospective comparative randomized double-blind study. Methods: 22 patients were included per group. The IOLs evaluated were the AcrySof IQ Vivity (Vivity group), AT LARA 829MO (AT Lara group), or TECNIS Symfony ZXR00 (Symfony group) and the monofocal AcrySof IQ SN60WF (Monofocal group). The variables analyzed were the light distortion index (LDI), best-fit circle radius (BFCRad), and self-reported vision quality with a questionnaire (QoV). Outcomes were evaluated at the 3-month follow-up visit. Results: Under monocular conditions, no differences between groups were detected for the LDI and BFCRad. Under binocular conditions, significant differences in both variables were produced. The Monofocal group reported better values than Symfony (P = .025; P = .024) and AT Lara (P = .002; P = .002) groups. The Vivity group reported better values than Symfony (P = .015; P = .014) and AT Lara (P = .001; P = .001) groups. Halos were not reported by 81.8% (18) of patients in the Vivity group, 90.9% (20) of patients in the Monofocal group, 50% (11) of patients in the AT Lara group, and 59% (13) of patients in the Symfony group. Conclusions: The diffractive EDOF IOL models examined in this study induced similar visual disturbances, which were worse than those produced by the nondiffractive extended-range IOL and the monofocal IOL. The nondiffractive lens and the monofocal lens did not show differences.
