Persistent corneal edema after collagen cross-linking for keratoconus

摘要

EDITOR: SHARMA AND ASSOCIATES RECENTLY PUBLISHED AN INTER-esting retrospective case series of patients who manifested persistent corneal edema after collagen cross-linking (CXL) for keratoconus. The authors analyzed the clinical data of 350 patients with keratoconus who underwent CXL and identified 10 patients with postoperative corneal edema (2.9%). Corneal edema improved in 4 and resolved in 1 patient, whereas 5 patients underwent penetrating keratoplasty for visual restoration. Based on these findings, the authors underscore the potential risk for endothelial damage and consequent corneal edema after CXL, although they recognize that CXL is a procedure demonstrating a strong overall safety profile.
