Corneal Collagen Cross-Linking for Ectasia (CXL)

2014-08-26 22:30:46 | BioPortfolio


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.
