摘      要：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 of TECNIS Symfony(ZXRoO)or monofocal IOLs were *** binocular static and dynamic defocus curves with corrected distance visual acuity were evaluated at one month ***:The ZXR00 group achieved signifcantly better intermediate(P=0.044)and near(P=0.017)visual acuity(VA)than the monofocal *** groups had similar uncorrected and corrected distance VA(P0.05,respectively).The dynamic defocus curve revealed a smoother decline from 0.0 D to-2.0 D in the ZXRo0 *** dynamic VA in the ZXR00 group was significantly better(P0.05)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 ZxRoo group.A positive correlation was observed between defocused dynamic and static VA in both groups(P0.001).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(P0.05).Conclusions:The EDOF IOL provided similar distant vision,better intermediate and near vision,and a better overall dynamic defocus curve than the monofocal *** dynamic defocus curve may be comprehensively applied to evaluate the all-distance dynamic visual performance post-cataract surgery.
