Abstract PURPOSE: To compare visual acuity at different distances after bilateral implantation of 1 of 4 multifocal intraocular lenses (IOLs).
SETTING: Fernández-Vega Ophthalmological Institute, Oviedo, Spain.
METHODS: This study evaluated consecutive patients who had bilateral implantation of a spherical multifocal IOL with a +4.00 diopter (D) addition (add) (AcrySof ReSTOR SN60D3) or an aspheric multifocal IOL with a +4.00 D add (AcrySof ReSTOR SN6AD3), +3.75 D add (Acri.LISA 366D), or +3.00 D add (AcrySof ReSTOR SN6AD1). Six months postoperatively, binocular measurement of corrected distance visual acuity (CDVA) at 4 m, corrected near visual acuity (CNVA) at 40 cm, and corrected intermediate visual acuity (CIVA) at 50, 60, 70, and 80 cm were performed; the defocus curve was also measured.
RESULTS: Each IOL model was implanted in 20 eyes (10 patients). All IOL models resulted in good distance vision, with no statistically significant differences between models. Patients with the +3.00 aspheric IOL had statistically better binocular CIVA at 50, 60, and 70 cm (P<.0001) and binocular CNVA at 40 cm (P = 3 x 10(-3)) than patients with the other IOL models.
CONCLUSION: Patients with bilateral multifocal aspheric IOLs with a lower add had better intermediate and distance near visual acuity than patients with bilateral multifocal spherical IOLs or bilateral aspheric IOLs with a higher add (c) 2010 ASCRS and ESCRS.
