Purpose: To compare new-generation multifocal intraocular lenses (IOLs) with monofocal IOLs. Design: Randomized prospective clinical trial. Participants: Sixty-two consecutive patients with cataract, seen between January of 2005 and January of 2006 at the Department of Ophthalmology of Palermo University Hospital in Italy, were bilaterally implanted with monofocal (AR 40, Advanced Medical Optics [AMO], Santa Ana, CA; 15 patients), multifocal refractive (Array SA40N, AMO; 16 patients), multifocal refractive (ReZoom, AMO; 15 patients), or multifocal diffractive pupil-independent (Tecnis ZM900, AMO; 16 patients) IOLs. Intervention: Bimanual phacoemulsification. Main Outcome Measures: Primary outcomes were far, near, and intermediate visual acuity of the 4 IOL-implanted groups. Secondary outcomes were defocusing curves, contrast sensitivity, patients' quality of life (7-item visual function questionnaire [VF-7], halos and glare presence, overall satisfaction), and spectacle independence. Snellen visual acuity was measured as uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), uncorrected near visual acuity (UCNVA), best distance corrected near visual acuity (BDCNVA), best corrected near visual acuity (BCNVA), uncorrected intermediate visual acuity (UCIVA), and best distance corrected intermediate visual acuity (BDCIVA). Results: UCNVA was 20/50 in the monofocal IOL group, compared with 20/32 or better in the multifocal IOL groups (P
