Corneal Collagen Cross-Linking for Ectasia (CXL)
Prospective, randomized multicenter study to determine the safety and effectiveness of performing corneal collagen cross-linking (CXL) using riboflavin and UVA light in eyes with ectasia after refractive surgery.
Subjects are randomized to a control group or a treatment group, with the control group crossed over to the treatment group at the 3 month visit. Fellow eyes may be treated at 3 months or later. Corneal collagen cross-linking is performed as a single treatment. Subjects are followed for 12 months after the procedure to evaluate the long term effects of corneal collagen cross-linking.
Allocation: Randomized, Control: Active Control, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Medical and Biotech [MESH] Definitions
An enzyme that catalyzes the formation of riboflavin from two molecules of 6,7-dimethyl-8-ribityllumazine, utilizing a four-carbon fragment from one molecule which is transferred to the second molecule. EC 220.127.116.11.
Enzyme which catalyzes the peptide cross-linking of nascent CELL WALL; PEPTIDOGLYCAN.
One of the protein CROSS-LINKING REAGENTS that is used as a disinfectant for sterilization of heat-sensitive equipment and as a laboratory reagent, especially as a fixative.
A naturally occurring furocoumarin, found in PSORALEA. After photoactivation with UV radiation, it binds DNA via single and double-stranded cross-linking.
An antineoplastic antibiotic produced by Streptomyces caespitosus. It is one of the bi- or tri-functional ALKYLATING AGENTS causing cross-linking of DNA and inhibition of DNA synthesis.
