Abstract
Purpose. To evaluate various available intraocular lenses (IOL) (PMMA, acrylic, heparin coated PMMA, and silicone) in patients with cataracta complicata and evaluate IOL tolerance, post-operative inflammation, cystoid macular edema, and posterior capsular opacification(PCO) requiring Nd:YAG capsulotomy. Design. randomized, double masked clinical trial. Participants. Patients evaluated in the Ocular Immunology and Uveitis Service of the Massachusetts Eye and Ear Infirmary and deemed to need cataract surgery by standard criteria were asked to participate in the clinical trial. Patients had to have a diagnosis of chronic uveitis, which was inactive for 3 months prior to cataract surgery. Results. Acrylic lenses appeared to provide the best overall results when evaluated for post-operative inflammation, PCO rates, visual acuity, and cystoid macular edema (CME) (compared to PMMA, silicone, and heparin coated PMMA).
