Abstract
Background:The aim of the study was to compare the dynamic defocus curve on patients post-implantation of the extended depth-of-focus(EDOF)and monofocal intraocular lens(IOL).Methods:A total of 62 age-related cataract patients receiving phacoemulsification with implantation ofTECNIS Symfony(ZXR00)or monofocal IOLs were enrolled.The binocular static and dynamic defocus curves with corrected distance visual acuity were evaluated at one month postoperatively.Results:The ZXR00 group achieved significantly better intermediate(P=0.044)and near(P=0.017)visual acuity(VA)than the monofocal group.Two groups had similar uncorrected and corrected distance VA(P＞0.05,respectively).The dynamic defocus curve revealed a smoother decline from 0.0 D to-2.0 D in the ZXR00 group.Defocused dynamic VA in the ZXR00 group was significantly better(P＜0.05)except at 0.0 D(P=0.724)and-0.5 D(P=0.176).The area under the curve(P=0.002)and corrected dynamic vision accommodation(P=0.001)derived from the dynamic defocus curves were better in the ZXR00 group.A positive correlation was observed between defocused dynamic and static VA in both groups(P＜0.001).Multiple linear regression analysis indicated that defocused static VA and cor-rected dynamic vision accommodation were significant influential factors for the defocused dynamic VA from-1.0 D to-3.0 D(P＜0.05).Conclusions:The EDOF IOL provided similar distant vision,better intermediate and near vision,and a better overall dynamic defocus curve than the monofocal IOL.The dynamic defocus curve may be comprehensively applied to evaluate the all-distance dynamic visual performance post-cataract surgery.
