Comparison Between Foldable (AcrySof) & Polymethyl Methacrylate (PMMA) IOLs in Formation of Posterior Capsular Opacification (PCO).
Ophthalmol Update Jan ;13(4):287-92.

Objective: The objective of this study was to compare foldable and polymethyl Methacrylate IOLs for formation of posterior capsular opacification in patients undergoing age related cataract surgery. Study Design: Randomized clinical trial. Setting: Layton Rehmatullah Benevolent Trust Hospital, Lahore. Duration: From March 2010 to September 2010. Subjects and Methods: The study included 200 patients undergoing cataract surgery and IOL implantation who were divided into two groups, each group comprising of 100 patients that fulfill the inclusion criteria. Foldable AcrySof IOL was implanted in group A and PMMA IOL was implanted in group B. The patients who underwent surgeries were followed and assessed for PCO formation at 01, 03 and 06 months period postoperatively. Results: No case of PCO was found in both groups at one month follow up. At 03 months follow up PCO developed in 01 out of 100 eyes (0.5%) in group B and no case of PCO was found in group A (0%). At 06 months follow up PCO developed in 19 out of 100 eyes (9.5%) in group B and no case of PCO was found in group A (0%). Conclusion: Implantations of Foldable Intraocular lenses (AcrySof) are associated with a reduced degree of Posterior capsular opacification formation and better visual outcome.
