Cornea Classic: Spoerl et al, 2007, the "Holy Grail of CXL".

Corneal collagen cross-linking has established itself as the only known treatment with a proven ability to arrest the progression of keratoconus. The efficacy and safety of the procedure have been entirely due to meticulous preparation by the innovators of this technique, before clinical application was confidently advocated. The article by Spoerl et al, entitled "Safety of UVA riboflavin crosslinking of the cornea," one of the most frequently cited articles in the journal " Cornea ," explains the logic behind the formulation of the "Dresdon protocol" that remains the gold standard in the treatment of keratoconus by collagen cross-linking.
