Efficacy S-formula and Kinetics of Non-oxygenmediated (Type-I) and Oxygen-mediated (Type-II) Corneal Cross-linking

Aims: To derive analytic formulas for the overall efficacy of corneal collagen crosslinking (CXL) based on coupled kinetic equations including both non-oxygen-mediated (NOM) and oxygen-mediated (OM) type-II mechanisms.
