Arms	Assigned Interventions
Active Comparator: 1 Corneal collagen cross-linking with riboflavin and UVA light	Procedure: Cross-linking with riboflavin/UVA light Cross-linking with riboflavin/UVA light Other Name: UV-X
Sham Comparator: 2 Riboflavin without UVA light	Procedure: Sham comparator Sham treatment with riboflavin in the absence of UVA light Other Name: Medio-Cross

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. 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.
