OBJECTIVE: Comparison of the visual performance between patients with Tecnis® MF ZM900, Acrysof® Restor® SN60D3, Acrysof® SN60AT and Acrysof® SN60WF intraocular lenses. METHODS: This prospective comparative study included 142 eyes of 71 patients in Sao Paulo University. The ophthalmologic evaluation performed included near, intermediate and distance corrected and uncorrected visual acuity, contrast sensitivity measurement and wavefront analysis. The minimum follow-up was 6 months. RESULTS: The mean age of patients was 60.7±6.6years in the Tecnis®MF, 63.1±4.4 years in-group Restor® 63.7±4.2 years in monofocal group (SN60AT in the fellow eye SN60WF). The Restor and Tecnis groups has uncorrected near and corrected distance visual acuity statistically superior compared to SN60AT/SN60WF group (p<0.001). There was no statistical difference between groups when compared uncorrected and best-corrected distance visual acuity (p=0.56). Contrast sensitivity in photopic conditions was significantly lower in the Restor and Tecnis group (p<0.001). The SN60AT showed higher spherical aberration compared to all other lenses (p<0.001). The Tecnis showed a lower mean values of spherical aberration compared to Restor lenses (p<0.001). CONCLUSION: Restor and the Tecnis had better near visual acuity than the SN60AT/SN60WF group. All intraocular lenses promoted good distance vision. The Tecnis group showed better contrast sensitivity, less aberrations and better intermediate vision than the Restor group.
