Transepithelial Corneal Collagen Crosslinking in Eyes With Progressive Keratoconus

Keratoconus is a corneal ectatic disease responsible for a loss of visual acuity when the steepening increases. Corneal collagen crosslinking (CXL) is a procedure that appears to halt or slow down the progression and avoid the visual impairment. However, such a technique requires the epithelium debridement, wich can be responsible for severs complications. This study evaluate the safety and efficacy of transepithelial corneal crosslinking with oxygen to halt or slow down the progression of keratoconus. Such a procedure avoids the epithelium debridement and the related complications.
