The latest revolutionary Keratoconus treatment is C3R (Corneal Collagen Crosslinking with Riboflavin) that has been proven to strengthen the weak corneal structure. This method works by increasing collagen crosslinking, which are the natural “anchors” within the cornea. These anchors are responsible for preventing the cornea from bulging out and becoming steep and irregular, consequence of advanced Keratoconus. C3R causes the collagen fibrils to thicken, stiffen, and crosslink & reattach to each other, making the cornea stronger and more stable thus provenly halting the progression of the disease. This technique can also be used in corneal ulcers and before LASIK treatment in high Myopes to reduce the risk of postoperative Keratectasia.
During the corneal crosslinking treatment, custom-made riboflavin drops saturate the cornea, which is then activated by ultraviolet light. This process has been shown in laboratory and clinical studies to increase the amount of collagen cross-linking in the cornea and strengthen the cornea.
Collagen crosslinking is not a cure for keratoconus.
The aim of this treatment is to arrest progression of keratoconus, and thereby prevent further deterioration in vision and the need for corneal transplantation. Glasses or contact lenses will still be needed following the cross-linking treatment (although a change in the prescription may be required) but it is hoped that it could limit further deterioration of vision.
