Official Title: Evaluation of the Aspheric ReSTOR IOL After Routine Cataract Extraction
Brief Summary: The purpose of this study is to evaluate the visual outcomes and patient satisfaction after bilateral implantation of the aspheric ReSTOR multifocal intraocular lens (IOL) and compare it to a historical control group of patients implanted bilaterally with the spherical ReSTOR multifocal

Current Primary Outcome: ETDRS uncorrected and best corrected visual acuity at distance, intermediate, and near, manifest refraction, distance corrected near visual acuity (DCNVA), and best near point (optimal reading distance). [ Time Frame: Preoperatively, 1, 3 and 6 months postoperatively ]
Original Primary Outcome: Same as current
Current Secondary Outcome: pupil size and contrast sensitivity under photopic and mesopic conditions wearing the best distance correction (the latter per eye and both eyes. Slit-lamp exam, eye dominance, reading speed test, and a quality of vision questionnaire. [ Time Frame: preoperatively, 1, 3, 6 month ]
Original Secondary Outcome: Same as current
