Refractive error, monocular and binocular uncorrected and corrected-distance visual acuity (UDVA, CDVA), uncorrected and corrected-distance intermediate visual acuity (UIVA, CDIVA) at 60 cm, uncorrected and corrected-distance near visual acuity (UNVA, CDNVA) at 40 cm, monocular and binocular defocus curve and rotational stability were measured. Patients also completed the Catquest-9SF questionnaire at the last postoperative visit.Results: The postoperative mean values of binocular logMAR CDVA, CDIVA and CDNVA were − 0.06± 0.06, 0.05± 0.07 and 0.07± 0.08, respectively. One hundred percent of patients showed a cumulative binocular CDVA ≥ 20/25, and 95.83% of patients showed a cumulative binocular CDIVA and CDNVA ≥ 20/32. The mean postoperative spherical equivalent was 0.07± 0.26D and 100% and 97.92% eyes were within ± 1.00D and ± 0.50D, respectively. The mean postoperative refractive cylinder was − 0.22± 0.29D and 100% and 89.58% eyes showed a value ≤ 1.00D and ≤ 0.50D, respectively. The defocus curves showed a wide range of useful vision, with visual acuity values > 0.2 logMAR. Mean absolute IOL rotation was 2.19± 2.17 degrees and all eyes had a rotation < 10 degrees. For the questionnaire, 95.83% of patients reported being quite satisfied to very satisfied with their vision and about 79.17% did not report any difficulty with their vision in their everyday life. Between 83.33% and 95.83% of patients reported no difficulty performing different tasks. No intra- and postoperative complications were reported during the follow-up.Conclusion: Our study shows that the TrivaT-aAY IOL provides good visual acuities at all distances and refractive outcomes with excellent rotational stability and with high satisfaction among our patients after its implantation.Keywords: astigmatism, toric, diffractive, trifocal, intraocular lens, cataract
