Keratoconus, is a disorder of the cornea, resulting in thinning that causes distortion and impaired vision. Until now, this condition has not been correctable with existing technologies. As the disease progresses rigid gas-permeable contact lenses are often the only course of action to provide better vision. Keratoconus is an irreversible and progressive disease and when the disease advances significantly a corneal transplant may be necessary due to extreme thinning, contact intolerance and scarring. A similar condition, Ectasia, can occur after an eye surgery when the eye is prone to develop a keratoconus-like corneal deformity.
Corneal Collagen Cross-linking with Riboflavin (C3R) has been demonstrated in Europe to strengthen a weakened corneal structure. This simple, well-tolerated procedure is performed by an ophthalmologist and begins with the application of riboflavin (vitamin B2) drops on the cornea which are then activated with a mild UV (Ultraviolet) light. The interaction of Riboflavin and UV light causes the links within the cornea to re-bond and strengthen over time. These natural links are responsible for maintaining stability of the corneal structure and preventing the cornea from irregular bulging and excessive steepening which lead to advanced Keratoconus. There are a large body of international Clinical Studies that have shown the safety and effectiveness of this procedure in the treatment and management of Keratoconus and Ectasia patients.
Corneal Collagen Crosslinking, which has demonstrated long-term stability, is a less invasive treatment as compared to corneal transplants. Dr. Roy has been instrumental in assisting us in getting the technology approved in Canada and his contribution to ophthalmology will be felt by thousands of patients that will benefit from this technology.”
Intacs prescription inserts are an exciting new option between contacts and a corneal transplant that may be the best possible option to stabilize the cornea and improve vision.
Intacs prescription inserts are indicated for use in the correction of nearsightedness and astigmatism for patients with Keratoconus, where contact lenses and glasses are no longer suitable.
