5. Study Description

Brief Summary
Prospective, randomized, single site study to determine the safety and effectiveness of performing corneal collagen cross-linking (CCCL)using riboflavin and UVA light in eyes with corneal ectasia or progressive keratoconus.
Detailed Description
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. Corneal collagen cross-linking is performed as a single treatment. Subjects are followed for at least 12 months to evaluate the long term effects of corneal collagen cross-linking. Subjects may be referred from other physicians but must return to Emory Vision for completion of all study visits.
