Keratoconus Progression After Corneal Cross-Linking in Eyes With Preoperative Maximum Keratometry Values of 58 Diopters and Steeper

Abstract

The incidence of progression (23% at 1 and 18% at 2 years, respectively) is considerably higher than in previously reported results of CXL in eyes with mean Kmax ≥58.0 D. To the best of our knowledge, this study represents the largest number of such steep corneas analyzed with respect to long-term progression after CXL.
