Purpose
This study will determine the efficacy of collagen cross linking for progressive keratoconus and ectasia after lasik. It will try and determine which is a more effective treatment: collagen cross linking alone or collagen cross linking combined with Intacs, a treatment which has already been proven to be effective in decreasing corneal curvature in patients with keratoconus.
