Corneal Collagen Crosslinking With Riboflavin for Keratoconus Treatment: A Brazilian Study
Recruitment status was Recruiting
Cross-linking of the cornea increases the mechanical and biochemical stability of the stromal tissue. The purpose of this study is to assess the effectiveness of riboflavin-ultraviolet light induced cross-linking of corneal collagen in improving visual acuity and reducing progression of keratoconus in the Brazilian population.

The eye with the worst visual acuity receives the treatment. (the other eye serve as control).
Procedure: Corneal Collagen Crosslinking
UV light and Riboflavin eyedrops every 5 minutes for 30 minutes.
No Intervention: B
The eye with the best visual acuity do not receive the treatment.
