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.

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.

The AcrySof ReSTOR SN6AD3 and Acri.LISA aspheric IOLs provided contrast sensitivity within normal range under photopic conditions and a reduction in contrast sensitivity under mesopic conditions, with no significant differences between the two brands.
