Refractive Changes After Two Years Accelerated Corneal Cross-Linking in Patients with Keratoconus

Purpose: To describe the visual and topographical changes after accelerated corneal collagen cross-linking (ACXL) in keratoconus-affected eyes. Methods: Clinical records of patients with keratoconus-affected eyes that underwent ACXL treatment and had 24 months of follow-up were reviewed. Data regarding demographics, visual acuity (VA), refraction and Sheimpflug values before and post ACXL were analyzed. We included patients with keratoconus older than 12 years old, with corneal thickness greater than 400 microns and steepest keratometry
