The purpose of this study is to evaluate visual outcome and patient satisfaction after implantation of a diffractive multifocal IOL (ReSTOR) in one eye and a refractive multifocal IOL (ReZoom) in the fellow eye after routine phacoemulsification and compare it to a control group of patients implanted bilaterally with ReSTOR with both eyes targeted for 0 to ±0.25 D, and to a group of patients implanted bilaterally with ReSTOR with the non-dominant eye targeted for +1.00 D and the dominant eye targeted for 0 to +0.25 D.
