C3R – Corneal Collagen Crosslinking with Riboflavin
Corneal Collagen Crosslinking with Riboflavin (C3R) is an advanced treatment for keratoconus and corneal ectasia, conditions that cause the cornea to become weak and progressively thinner. This minimally invasive procedure strengthens the cornea by using ultraviolet (UV) light and riboflavin (Vitamin B2), which enhances collagen crosslinking, preventing further weakening.
At Desai Eye Hospital, we offer C3R to stabilize the cornea, slow disease progression, and improve vision quality, ensuring long-term eye health.
How Does It Work?
- Designed to treat keratoconus and corneal thinning disorders.
- Riboflavin eye drops are applied to the cornea.
- The cornea is exposed to controlled UV light.
- This strengthens collagen fibers and enhances corneal stability.
- The procedure is safe, non-invasive, and takes about 30-60 minutes.
- Slows or halts the progression of keratoconus.
- Can delay or prevent the need for a corneal transplant.
- Improves corneal shape and enhances long-term vision stability.
