This study aimed to compare clinical outcomes obtained after implanting two different optical designs of EDOF IOLs: the Mini Well Ready (SIFI Medtech, Catania, Italy) and Tecnis Symfony (Abbott Laboratories, Illinois, USA).Methods: The retrospective observational study included 61 patients (122 eyes) who underwent bilateral implantation of the Mini Well Ready IOL (32 patients) or the Tecnis Symfony IOL (29 patients). The following preoperative and postoperative parameters were evaluated: spherical equivalent, anterior astigmatism, pupil size, monocular and binocular uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA), monocular and binocular uncorrected intermediate visual acuity (UIVA) and distance-corrected intermediate visual acuity (DCIVA), monocular and binocular uncorrected near visual acuity (UNVA) and distance-corrected near visual acuity (DCNVA). In the 6 months postoperative period, defocus curve, contrast sensitivity, photopic phenomena, and posterior capsule opacification were assessed.Results: The patients receiving the Tecnis Symfony had slightly better monocular and binocular UDVA and CDVA than with the Mini Well Ready IOL, the differences were not statistically significant. Whereas the UIVA, DCIVA, UNVA, DCNVA, UNVA and DCNVA values were higher in the Mini Well Ready group, the differences were not significant. There were no significant between-group differences regarding the defocus curve for the vast majority of tested vergences. Dysphotopsias postoperatively were assessed at 6 months.Conclusion: Patients receiving both the Mini Well Ready and Symfony IOLs had excellent visual acuity outcomes and spectacle independence.Keywords: cataract, extended depth of focus, defocus curve, intraocular lens
