Comparing the visual outcome, visual quality, and satisfaction among three types of multi-focal intraocular lenses.

ABSTRACT: This study compared the visual outcome, visual quality, and satisfaction following implantation of the Mix-and-Match bifocal IOLs (+ 2.75 D and + 3.25 D add power Tecnis Multifocal Model), EDOF IOL (Tecnis Symfony IOL), and Trifocal IOL (FineVision PodFT, PhysIOL). All outcomes were compared among the three groups. The manifest refraction indicated that the EDOF group had significantly higher myopic spherical equivalent values than did the others. In the terms of visual acuity, there were no significant differences in far or intermediate visual acuity among the three groups. Only in near (33 cm), the EDOF group had significantly worse binocular visual acuity than did the Trifocal group (p = 0.002). Regarding to defocus curve, the Trifocal group had better defocus curves at near distances (- 2.0 to - 3.5 D; p = 0.001 vs. EDOF) than did the other two groups. In contrast sensitivity test, the EDOF group had relatively lower value than did the other two groups. In reading speed, only at 0.3 logMAR (6.5-point font), Mix-and-Match group had a significantly higher reading speed than did the other two groups (p = < 0.001 vs. EDOF, p = 0.007 vs. Trifocal). also Mix-and-Match group showed significantly fewer visual artifacts. There were no differences between the three groups in terms of patient satisfaction.ClinicalTrials.gov number: NCT04019691.

Project description:BackgroundTo compare the visual performance of MF30 asymmetric refractive multifocal intraocular lenses (MIOLs) with ZMB00 all optic zone diffractive MIOLs.MethodsThis is a prospective study. Patients that underwent phacoemulsification were divided into two groups according to the type of MIOLs used: 35 patients were implanted with asymmetric refractive MIOLs and 35 patients with all optic zone diffractive MIOLs. Visual acuity (VA), refraction, defocus curves, objective optical quality, and a questionnaire evaluating quality of life were measured at 3 months postoperatively.ResultsThere were no significant differences between the two groups in uncorrected distance visual acuity (UDVA), uncorrected near visual acuity (UNVA), best-corrected distance visual acuity (BCDVA), or distance-corrected near visual acuity (DCNVA). However, the uncorrected intermediate VA was 0.24±0.10 in the refractive group and 0.31±0.13 in the diffractive group (P<0.05), and the distance-corrected intermediate VA was 0.22±0.09 in the refractive group and 0.31±0.14 in the diffractive group (P<0.05). Defocus curves showed two peaks of maximum vision in both groups. However, the curve between the two peaks in the refractive group was smoother than that of the diffractive group. The modulated transfer function cut-off frequency was 22.74±12.29 c/d in the refractive group and 30.50±10.04 c/d in the diffractive group (P<0.05). The Optical Quality Analysis System (OQAS) values 100% (OV100%) was 0.75±0.41 in the refractive group and 1.02±0.34 in the diffractive group (P<0.05), while the OV20% was 0.52±0.34 in the refractive group and 0.71±0.25 in the diffractive group (P<0.05). There was no significant difference between the two groups in overall satisfaction, spectacle independence ratio, or visual interference phenomenon.ConclusionsBoth MIOLs achieve good VA at distance and near vision. Oculentis MF30 showed better intermediate VA, and Tecnis ZMB00 appears to have better objective visual quality.Trial registrationNCT02234635 (http://www.clinicaltrials.gov).
