    Abstract:
    PURPOSE: To compare visual acuity after bilateral implantation of 2 models of multifocal aspheric intraocular lenses (IOLs). SETTING: Fernández-Vega Ophthalmological Institute, Oviedo, and University of Valencia, Valencia, Spain. METHODS: Prospective study of patients who had bilateral implantation of an AcrySof ReSTOR SN6AD3 IOL (Group 1) or an Acri.LISA 366D IOL (Group 2). Six months postoperatively, binocular uncorrected and best corrected distance visual acuity, uncorrected-distance and best distance-corrected near visual acuity, best corrected intermediate visual acuity, and the defocus curve were measured in both IOL groups. RESULTS: Group 1 comprised 36 eyes (18 patients) and Group 2, 40 eyes (20 patients). The mean binocular values in Group 1 and Group 2, respectively, were as follows: best corrected distance acuity, -0.05 +/- 0.09 logMAR and -0.08 +/- 0.08 logMAR (both approximately 20/20); best distance-corrected near acuity, -0.01 +/- 0.16 logMAR and -0.05 +/- 0.07 logMAR; best corrected intermediate acuity at 80 cm, 0.20 +/- 0.18 logMAR (approximately 20/32) and 0.16 +/- 0.13 logMAR (approximately 20/25) and at 60 cm, 0.16 +/- 0.16 logMAR (approximately 20/25) and 0.18 +/- 0.13 logMAR (approximately 20/25). There were no statistically significant between-group differences in visual acuity at any distance (P>.3). Defocus curves were similar between groups (2.00 to -5.00 diopters) (P>.26). CONCLUSIONS: The 2 multifocal aspheric IOL models gave similar and good high-contrast visual acuity at distance and near. Intermediate visual acuity, also comparable between IOL models, was better than published results of a spherical IOL model.
