Improvements in patient-reported outcomes and visual acuity after bilateral implantation of multifocal intraocular lenses with +3.0 diopter addition: Multicenter clinical trial

Purpose: To assess changes in patient-reported outcomes, satisfaction, vision quality, and visual acuity after bilateral implantation of multifocal intraocular lenses (IOLs) with a 3.00 D addition (add) in cataract patients. Setting: Twelve study centers, United States. Design: Randomized multicenter clinical trial. Methods: In this 6-month trial, cataract patients had bilateral implantation of the AcrySof IQ ReSTOR +3.0 IOL (model SN6AD1). Patient-reported outcomes were collected using the Cataract TyPE questionnaire. Clinical outcomes included uncorrected near (UNVA), uncorrected intermediate (UIVA), and uncorrected distance (UDVA) visual acuities. Results: The study comprised 147 patients. From preoperatively to 6 months postoperatively, the mean UDVA improved from 0.45 logMAR (approximate Snellen, 20/56) to 0.04 logMAR (20/22 Snellen), the mean UIVA from 0.56 logMAR (20/73) to 0.17 logMAR (20/30), and the mean UNVA from 0.62 logMAR (20/83) to 0.10 logMAR (20/25); all improvements were clinically and statistically significant (P
