The Effects of Corneal Collagen Cross-linking
Phase III Study of Corneal Collagen Cross-linking Using Two Different Techniques.

The corneal collagen cross-linking treatment has been used with increasing success to treat corneal dystrophies such as "keratoconus." Recent advances have allowed different techniques for performing this cross-linking treatment. This study investigates the effects of corneal cross-linking using different surgical techniques.
