Brief Summary: This study is being conducted to evaluate the safety and efficacy of isotonic riboflavin for corneal collagen crosslinking for keratoconus and corneal ectasia. will determine the safety and efficacy of corneal collagen crosslinking (CXL) performed with two different riboflavin formulations for reducing corneal curvature.
Detailed Description: This study will determine the safety and efficacy of corneal collagen crosslinking (CXL) performed with two different riboflavin formulations for reducing corneal curvature. Subjects will be randomized to one of 2 groups. One group will be treated with a methylcellulose riboflavin solution and the other group will be treated with a dextran riboflavin solution. Both groups will be exposed to 3mW/cm2 of continuous UVA light for a total of 30 minutes; each group will continue to be administered the designated riboflavin drops during UV exposure.

The primary efficacy parameter that will be evaluated over time is maximum keratometry (Kmax) in the randomized eyes for each treatment group.

The secondary efficacy parameter will be to determine if the two treatment groups equivalent in their Kmax change at 12 months after treatment compared with baseline.
