Clinical Visual Outcomes Over a Range of Vision Following Cataract Surgery with Bilateral Implantation of a Hybrid Multifocal and Extended Depth of Focus Intraocular Lens

Abstract

Abstract Background: To evaluate binocular visual outcomes, with emphasis on near intermediate vision at 50 cm, in patients undergoing bilateral cataract surgery with implantation of the Synergy hybrid intraocular lens with multifocal and extended depth of focus diffractive optics. Methods: A chart review was conducted of all patients undergoing phacoemulsification by a single surgeon with bilateral implantation of a Synergy IOL from August 2021 through March 2023. Primary endpoints were Uncorrected Distance Visual Acuity (UDVA), Uncorrected and Distance-Corrected Near Visual Acuity (UNVA and DCNVA, respectively) at 33 cm, Corrected Distance Visual Acuity (CDVA), and Distance-Corrected Intermediate Visual Acuity at 50 and 66 cm (DCIVA-50 and DCIVA-66, respectively). Results: Eighty-six eyes of 43 patients (26 or 60% female, mean age 70 years) were included with a mean followup of 42 days. Mean values for binocular visual acuity were as follows: UDVA 0.01 ± 0.05 logarithm of the minimum angle of resolution (logMAR), UNVA 0.01 ± 0.03 logMAR, CDVA 0.00 ± 0.00 logMAR with a mean spherical equivalent of 0.04 diopters ± 0.22, DCNVA 0.00 ± 0.00 logMAR, DCIVA-50 0.04 ± 0.17 logMAR, and DCIVA-66 0.12 ± 0.07 logMAR. Conclusions: The Synergy hybrid IOL achieved excellent visual acuity at a distance of 50 cm, corresponding to many intermediate tasks, as well as distance, intermediate, and near visual acuity at traditionally measured ranges.
