Influences of optic edge design on posterior capsule opacification and anterior capsule contraction

Abstract

Purpose: To investigate the influence of optic edge design on posterior capsule opacification (PCO) and anterior capsule contraction (ACC). Methods: A total of 43 eyes of 43 patients scheduled to undergo cataract surgery were included in this study. Patients received either a Sensor® AR40 intraocular lens (IOL) or a Sensor® AR40e IOL. The area of the anterior capsule opening (ACO) was determined by diaphanoscopy using the anterior eye segment analysis system EAS-1000 at 1day, 1week and 1, 3, 6 and 12 months postoperatively. Posterior capsule opacification was evaluated objectively in two ways, using either the EAS-1000 or POCOman. Results: There was no significant difference between the two groups in either ACO area or percentage reduction of ACO area at any time-point after surgery. The difference in the degree of PCO 1year after surgery was not significant when measured by either the EAS-1000 or POCOman. Conclusion: A sharp IOL edge is required to prevent PCO. Sharp-edged IOLs do not appear to be a risk factor for ACC. © 2007 Acta Ophthalmol Scand.
