Comparison of dynamic defocus curve on cataract patients implanting extended depth of focus and monofocal intraocular lens
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).

| description | 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 of TECNIS 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 corrected 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 distance 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. |
