Clinical Results of Rollable IOL Implantation After Bimanual Microincision Phacoemulsification

Abstract

Purpose: To retrospectively evaluate the clinical results of insertion of a hydrophilic acrylic plate posterior chamber intraocular lens (ThinOptX) after bimanual microincision phacoemulsification. Methods: Thirty-four eyes of 30 patients who underwent bimanual phacoemulsification and ThinOptX implantation through a 2.0 mm incision between July 2004 and May 2006 were followed-up for more than 12 months. We examined best corrected visual acuity (BCVA), refractive errors, corneal endothelial cell density, halo and contrast sensitivity, posterior capsule opacification (PCO), and intraoperative and postoperative complications. Results: The preoperative mean logMAR BCVA was 0.43±0.24, and the postoperative BCVA was 0.04±0.09 after 6 months and 0.14±0.12 after 12 months. The preoperative corneal endothelial cell density was 2562±347.90 cells/mm2, and decreased to 2241±294.88 (cells/mm2) at 12 months postoperative. Postoperative contrast sensitivity at 6 months was increased in both photopic and mesopic condition. Halo was noted in all examined eyes. A PCO of 29% was evaluated at 6 months postoperative and a PCO of 52% was evaluated at 12 months postoperative. Conclusions: Bimanual phacoemulsification and ThinOptX implantation through a 2.0 mm incision resulted in good initial visual outcome and correction of refractive errors. However, problems such as halo and PCO associated with IOL design were noted. Therefore, further evaluation and correction of the IOL are needed.
