Effect of lens style on postoperative refractive astigmatism after small incision cataract surgery

Abstract

Purpose: To evaluate the astigmatic results of two popular foldable intraocular lenses when standard surgical approaches are used in rural private practice in Australia. Methods: Four hundred consecutive cataract operations were followed in a prospective study. The refractive results of patients receiving the Alcon Acrysof MA30 lens were compared to those receiving the Allergan silicone S140 lens. All patients were over 60 years of age and had no intercurrent ocular disease. Refractive and keratometric astigmatism was analysed both by vector analysis and as an absolute measure. Results and conclusion: The Acrysof lens is associated with less postoperative astigmatism (P = 0.01), than the Silicone S140 lenses.
