ReSTOR® Diffractive versus Array®2 Zonal-progressive Multifocal Intraocular Lens: a Contralateral Comparison

PURPOSE. To evaluate near and distance visual performance after implantation of a diffractive multifocal intraocular lens (MIOL) (AcrySof ReSTOR ® ) or a refractive MIOL (Array ® 2) in bilateral cataract surgery. METHODS. In this prospective, comparative trial, 18 patients with bilateral cataract were selected to have lens surgery with asymmetric MIOL implantation. Eighteen eyes received ReSTOR MIOL and the 18 fellow eyes were implanted with Array 2. Five months after second lens implantation, main postoperative outcomes were uncorrected and distance corrected near visual acuities (VA). Secondary outcomes were distance VA and near acuity with power add, contrast sensitivity with and without…
