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 enrolled.The binocular static and dynamic defocus curves with corrected distance visual acuity were evaluated at one month postoperatively.Results:The ZXR00 group achieved signifcantly 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 ZXRo0 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 ZxRoo 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. 展开更多

A double-zone aspheric diffractive intraocular lens (IOL) was designed and manufactured aiming to regain a continuous range of clear vision for pseudophakic presbyopia. After obtaining the IOL structure parameters through optimization based on an aphakic model eye, its imaging performances were analyzed in the model eye. The modulation transfer function at 50 cycles/mm remained above 0.29 within ±5° field of view for object distance ranging from 6 to 0.66 m. In addition, the imaging qualities are robust for pupil changes, polychromatic light, and different corneal asphericities. The manufactured IOL exhibits the abilitv to extend depth of focus. 展开更多

Background:Presbyopia has become a global disease affecting the world's aging population.Among various treatments,cataract extraction and intraocular lens(IOL)implantation have become the most popular and common methods of presbyopia correction.During the twentieth century,IOLs have underwent significant innovation and advancements to meet the patients'high demands for functional vision at all distances.Main Text:To meet the increasing needs for excellent near and intermediate vision for daily activities,some premium IOLs with more than one focus have been developed,for example,the refractive MfIOLs,diffractive MfIOLs,extended depth of field(EDOF)IOLs,and accommodating IOLs(AIOLs)were introduced to meet this need.In addition,the add-on MfIOLs have been explored as promising supplementary IOLs for pseudophakic presbyopia.When selecting the MfIOLs,the IOLs'features,patients’characteristics,preoperative eye conditions,and treatment expectations should be considered.Conclusions:In this review,we focus on the multifocal IOLs(MfIOLs)commonly used for presbyopia correction and systematically summarized their optical designs and clinical outcomes.More evidence-based studies are required to provide guidelines for MfIOL selection,provide maximum visual benefits,and develop personalized visual solutions in the future. 展开更多
