Mechanical epithelial removal in cross-linking may have fewer short-term complications
Corneal collagen cross-linking performed with transepithelial phototherapeutic keratectomy may result in more short-term complications compared with mechanical epithelial removal in keratoconus patients, according to a study.The nonrandomized retrospective study evaluated 153 eyes that had transepithelial PTK (group 1) and 256 eyes that had mechanical epithelial removal (group 2) to compare complications within the first 3 months after corneal collagen cross-linking.
