Posterior Capsular Opacification after PMMA and Hydrophobic Acrylic Intraocular Lens Implantation

Material & Methods: A retrospective chart review of all patients undergoing phacoemulsification with implantation of posterior chamber IOL by a single surgeon from February 2000 to April 2007 was done in this study. The operated eyes of the patients were divided into 2 groups. Group A eyes were implanted a PMMA IOL (LX10 BD, Alcon) while group B eyes were implanted a Hydrophobic Acrylic (Acrysof multi-piece, Alcon) IOL. A detailed analysis of the charts was done to identify all the patients in both groups who presented with decreased visual acuity due to posterior capsular opacification (PCO) more than 2 years after cataract surgery. The charts of these patients were further screened to identify those patients who had visually significant PCO (best corrected visual acuity of <6/9) requiring YAG posterior capsulotomy. Patients with any posterior capsule plaque or rupture per-op, IOL implantation in the sulcus and significant macular disease were excluded from the study.
