Effect of Glistening-Free Intraocular Lens on Intraocular Straylight

Abstract

Purpose: To compare intraocular straylight between glistening-free and conventional intraocular lenses in pseudophakic eyes. Methods: Straylight values were measured prospectively in 21 eyes with glistening-free pseudophakic lenses (group A, model enVistaTM, Bausch & Lomb, Inc., USA) and 79 eyes with conventional hydrophilic pseudophakic lenses (group B, model Akreos MI-60, Bausch & Lomb, Inc., USA). Best corrected visual acuity (BCVA) and straylight were measured preoperatively and 1 month and 2 months postoperatively using C-quant straylight meter (Oculus GmbH, Wetzlar, Germany). Results: There were no statistically significant differences of BCVA preoperatively or 2 months postoperatively between the 2 groups (p > 0.05). BCVA and straylight significantly improved after the operation (p 0.05). Conclusions: In terms of straylight, glistening-free intraocular lenses were not beneficial. Although straylight was not statistically significant, other correlations between glistening and visual function should be investigated. J Korean Ophthalmol Soc 2014;55(7):1001-1006
