Drug classCorneal cross-linking agent
TargetCorneal collagen (riboflavin-mediated photochemical cross-linking)
ModalitySmall molecule
Therapeutic areaOphthalmology
PhasePhase 3

Mechanism of action

The treatment involves instillation of riboflavin (vitamin B2) onto the cornea followed by exposure to UVA light, which creates cross-links between collagen fibers in the corneal stroma. This increases corneal rigidity and biomechanical strength, preventing further corneal ectasia and visual deterioration in progressive keratoconus and other corneal disorders.
