Abstract: Corneal collagen cross-linking can effectively prevent or delay the progression of keratoconus by increasing corneal stiffness and biomechanical stability. To avoid irreversible damage to corneal endothelial cells and intraocular tissues caused by ultraviolet radiation, the standard protocol requires that the thinnest cornea stroma must have a minimal thickness of 400 μm, which excludes the thin keratoconic corneas. In order to break this limitation, plentiful scholars have being ameliorated the standard protocol. So, this article reviews and summarizes the modified corneal collagen cross-linking protocols for thin keratoconic corneas.

Key words: Keratoconus, Corneal collagen cross-linking, Thin cornea, Riboflavin, Treatment
