© The Author(s) 2022.Objective: To compare the visual outcomes of a non-diffractive extended-depth-of-focus (EDoF) intraocular lens (IOL) with an enhanced monofocal IOL. Methods: We evaluated 76 eyes from 38 patients who had undergone bilateral cataract surgery with implantation of either an EDoF IOL (AcrySof IQ Vivity, n = 40 eyes) or an enhanced monofocal IOL (Tecnis Eyhance, n = 36 eyes). Objective refraction, monocular and binocular uncorrected and corrected distance visual acuity (UDVA, CDVA), uncorrected and distance-corrected intermediate visual acuity (UIVA, DCIVA), uncorrected and distance-corrected near visual acuity (UNVA, DCNVA), binocular defocus curves, contrast sensitivity, halo and glare perception, and spectacle independence were compared. Results: Monocular and binocular UDVA, CDVA, UIVA, and DCIVA were comparable in both groups, whereas UNVA and DCNVA were significantly better with the Vivity group than with the Eyhance group. The two groups had no statistically significant difference regarding photopic and scotopic contrast sensitivities or halo and glare perception. Compared to the Eyhance IOL, the Vivity IOL had a larger landing zone in the defocus curve and provided higher spectacle independence for near vision. Conclusion: Both the AcrySof IQ Vivity and Tecnis Eyhance IOLs had excellent distant and intermediate visual acuity, while the former had more satisfactory near vision outcomes with greater spectacle independence rate. No differences were obtained between two IOLs in terms of patient satisfaction and visual disturbances such as halo and glare.
