Lens Position of the AcrySof Angle Supported Phakic Intraocular Lens in Myopic Patients,RAMY R. RIAD, YEHIA M. SALAH EL DIN and MOSTAFA A. EL HELW
Abstract
Background: Myopia is a common finding in the popula-tion; it can be treated in several ways. Phakic IOLs is one among other available options of treatment. Angle-supported phakic IOLs rest in the angle of the anterior chamber and vault above the pupil. They have caused severe endothelial cell loss in the past due to their forward movement and their contact with the corneal endothelium.
Objectives: To assess the position of the AcrySof angle-supported phakic IOL in the anterior chamber angle with the Scheimpflug image and its stability over time.
Patients and Methods: Thirty-two eyes were included in this study. They all had moderate to high myopia. The patients were selected from the outpatient clinic of Kasr Al Aini Hospital Cairo University between June 2010 and May 2011. After a full review of the patient's medical and ophthalmic history, all patients received complete ophthalmological examination. Surgery was then done followed by Scheimpflug imaging at 3 and 6 months postoperatively.
Results: The anterior chamber depth remained stable over time. The position of the IOL in the anterior chamber also remained stable over time indicating IOL stability.
Conclusion: The AcrySof angle-supported pIOL main-tained safe distances between the anterior surface of the pIOL and corneal endothelium and between the posterior surface of the pIOL and crystalline lens. Larger patient samples with lower values of preoperative anterior chamber depth and longer follow-up are needed to draw definitive conclusions.
