BACKGROUND: The aim was to evaluate visual performance and wavefront error after implantation of three models of Acrysof ReSTOR multifocal intraocular lenses (MIOLs). METHODS: This prospective comparative six-month study comprised 60 eyes having phacoemulsification and implantation of three diffractive AcrySof ReSTOR MIOLs: SN60D3 +4.00 D spherical MIOL (group 1), SN6AD3 +4.00 D aspheric MIOL (group 2) and SN6AD1 +3.00 D aspheric MIOL (group 3). RESULTS: The distance visual acuity was at least 0.1 logMAR in 88.8 per cent of group 1, 88.8 per cent of group 2 and 87.5 per cent of group 3. The distance-corrected near vision was 0.02 ± 0.04 logMAR in group 1, 0.02 ± 0.05 logMAR in group 2 and 0.01 ± 0.03 logMAR in group 3 (p = 0.822). The distance-corrected intermediate vision was 0.26 ± 0.07, 0.22 ± 0.09 and 0.04 ± 0.05, respectively (p < 0.001). The root-mean-square (RMS) of ocular spherical aberration was significantly lower in groups 2 and 3 compared to group 1 (p = 0.048). CONCLUSION: All diffractive MIOLs provided good vision for far and near. ReSTOR MIOL +3.00 also restored intermediate vision. Aspheric MIOLs +4.00 and +3.00 induced significantly lower spherical aberration compared to spherical MIOL +4.00.
