Li S, et al. - Authors sought to compare the postoperative pain and epithelial healing time in conventional and subepithelial accelerated corneal collagen cross-linking (CXL) for progressive keratoconus. They noted a significant improvement in the postoperative pain as well as reduced epithelial healing time for the treatment of keratoconus with subepithelial accelerated CXL. In the subepithelial group, no complications developed, whereas in 3 eyes in the conventional group peripheral corneal sterile infiltrate was observed, which disappeared after being treated with steroids for a week.
