Avedro completes 1-year follow-up in collagen cross-linking trial

WALTHAM, Mass. — Avedro has completed 1-year follow-up visits in two phase 3 studies that are evaluating the safety and efficacy of corneal collagen cross-linking, according to a company press release.

The multicenter trials are looking at cross-linking for the treatment of progressive keratoconus and ectasia after refractive surgery. The procedure has already been approved for use outside of the United States, according to the release.

"Avedro's efforts to make this clinically important treatment available to U.S. patients is applauded by all U.S. ophthalmologists who today lack any approved therapeutic treatment to halt the progression of these sight-threatening conditions," Peter S. Hersh, OSN Refractive Surgery Board Member and medical monitor for the Avedro trial, said in the release.
