Purpose: To compare the outcomes of accelerated versus standard corneal cross-linking for the treatment of progressive keratoconus.
Methods: In this retrospective comparative study, 63 eyes of 40 patients with progressive keratoconus were divided into two groups; 27 eyes in group one were treated with an accelerated protocol (10 mW/cm , 9 min) and 36 eyes in group two were treated with the standard method (3 mW/cm , 30 min). Visual acuity, refraction, corneal topography, corneal tomography, and anterior and posterior corneal higher-order aberrations (HOAs) were assessed preoperatively and 18-30 months postoperatively.
