PURPOSE: To assess the visual results after bilateral implantation of the bifocal Acri.LISA 366D intraocular lens (IOL) (Acri.Tec AG). SETTING: Fernández-Vega Ophthalmological Institute, Oviedo, Spain. METHODS: Eighty-one patients had bilateral implantation of the distance-dominant bifocal Acri.LISA 366D IOL in a prospective study. Monocular and binocular best corrected distance visual acuity and best distance-corrected near visual acuity, binocular best distance-corrected intermediate visual acuity, and distance contrast sensitivity under photopic (85 cd/m(2)) and mesopic (5 cd/m(2)) conditions were determined. RESULTS: At the 3-month postoperative visit, the mean binocular best corrected distance acuity was 0.048 +/- 0.111 logMAR and the mean binocular best distance-corrected near acuity, 0.012 +/- 0.0084 logMAR (both approximately 20/20). The mean binocular best distance-corrected intermediate acuity changed significantly as a function of the distance of the test, from 0.012 +/- 0.084 logMAR (approximately 20/20) at 33 cm to 0.265 +/- 0.099 logMAR (approximately 20/40) at 70 cm (P<.01). Contrast sensitivity was within normal limits under photopic and mesopic conditions. Binocular contrast sensitivity was statistically significantly better than monocular contrast sensitivity at all spatial frequencies under both illumination levels (P<.01). CONCLUSION: The Acri.LISA 366D IOL provided a satisfactory full range of vision; a high level of uncorrected and corrected distance, intermediate, and near acuity; and improved contrast sensitivity under photopic and mesopic conditions.
