About this trial

Study is testing the efficacy of treating corneal thinning conditions with Vitamin B2 (Riboflavin) and the application on UV Light.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Presence of central or inferior corneal steepening

Axial topography consistent with keratoconus, post-surgical ectasia, or pellucid marginal degeneration

Fleischer ring

Vogt's striae

Disqualifiers

Eyes classified as either normal or atypical normal on the severity grading scheme

Corneal pachymetry at the screening exam that is < 400 microns at the thinnest point in the eye(s) to be treated when the transepithelial (isotonic) riboflavin solution alone will be used or < 300 microns when the hypotonic riboflavin will be used.

History of or active corneal disease (e.g., herpes simplex, herpes zoster keratitis, recurrent erosion syndrome, acanthamoeba, etc.)

Clinically significant corneal scarring in the CXL treatment zone that is not related to keratoconus or, in the investigator's opinion, will interfere with the cross linking procedure
