    Corneal collagen crosslinking (CXL) has been well established to halt the progression of ectasia and keratoconus. Following several years of using CXL for the treatment of ectasia, Dr. A. John Kanellopoulos and colleagues introduced the "Athens Protocol," or same-day topography-guided partial PRK and CXL. In this presentation, Dr. Kanellopolous reviews the conventional uses of CXL and also cases in which it helped reduce scarring--in theory by eliminating keratocytes--through the Athens Protocol. Dr. Kanellopoulos suggests there may be a role for CXL as an adjunct procedure for treating infectious keratitis in severely scarred or abnormal corneas.
