Photorefractive intrastromal crosslinking for correction of hyperopia: 12-month results

Abstract

Purpose:To evaluate the efficacy of epithelium-on photorefractive intrastromal crosslinking (PiXL), a noninvasive procedure to reduce refractive error in patients with low hyperopia.Setting:Gemini Eye Clinic, Zlin, Czech Republic.Design:Prospective single-center study.Methods:Twenty-two low hyperopic eyes were enrolled and underwent PiXL treatment according to a standardized treatment protocol. Visual acuity, subjective distance refraction, keratometry, topography, pachymetry, subjective discomfort, and endothelial cell density (ECD) were recorded during 12-month follow-up.Results:In 22 eyes, the median manifest refraction decreased significantly (P
