Keratoconus Disease

Keratoconus typically first appears in individuals who are in their late teens or early twenties, and may progress for 10-20 years and then slow or stabilize. Each eye may be affected differently. In the early stages of keratoconus, people might experience:

• Slight blurring of vision
• Distortion of vision
• Increased sensitivity to light

The cornea is responsible for focusing most of the light that comes into the eye. Therefore, abnormalities of the cornea, such as keratoconus, can have a major impact on how an individual sees the world, making simple tasks such as driving a car or reading a book very difficult.¹

Keratoconus:

• Can result in significant vision loss
• May lead to corneal transplant in severe cases
• Affects both males and females
• Affects all ethnicities
• 10% of people with KC have affected relatives
• People with Down syndrome are 20 times more likely to be affected

iLink™ corneal cross-linking is a minimally invasive outpatient procedure that combines the use of ultraviolet light and specially formulated eye drops to stiffen and strengthen corneas that have been weakened by disease or refractive surgery. Cross-linking is considered the standard of care around the world for progressive keratoconus and corneal ectasia following refractive surgery.²

Is iLink™ Covered by Insurance?

The medical necessity of iLink™ has become widely recognized. As a result, commercial insurance coverage for the procedure is now over 95% in the United States.

Corneal Cross-Linking³

• Creates new corneal collagen cross-links
• Results in a shortening and thickening of the collagen fibrils
• Leads to the stiffening of the cornea

Riboflavin

Under the conditions used for iLink™ corneal cross-linking, specially formulated pharmaceutical-strength riboflavin eye drops called Photrexa® (riboflavin 5’-phosphate ophthalmic solution) and Photrexa® Viscous (riboflavin 5’-phosphate in 20% dextran ophthalmic solution) help enable the cross-linking reaction.

Ultraviolet Light (UV)

iLink™ corneal cross-linking applies an artificial source of ultraviolet light from a machine called the KXL System once the cornea has been soaked in the Photrexa® and Photrexa® Viscous eye drops. This process works to stiffen the cornea by increasing the number of molecular bonds, or cross-links, in the collagen.

Combining Riboflavin and UV Light

Using Photrexa® and Photrexa® Viscous riboflavin eye drops, combined with ultraviolet light from the KXL system, the iLink™ procedure stiffens and strengthens the cornea to slow or halt progressive keratoconus.

Is Cross-Linking Right for Me?

Patients who have been diagnosed with progressive keratoconus or corneal ectasia following refractive surgery should ask their doctor about iLink™ corneal cross-linking.

Our practice is proud to offer patients the first and only FDA-approved therapeutic solution for the treatment of progressive keratoconus. Now, patients who once had little to no therapeutic option to treat keratoconus have the opportunity to slow or halt the progression of this sight-threatening disease.

Dr. Garcia performed crosslinking on a Keratoconus patient that just happens to work for OMNI! Brea is loving her new “eyes” and vision. As you can see in the photo, Brea is all smiles!

If you or someone you know has symptoms of Keratoconus, bulging of the cornea and vision loss, please reach out to OMNI and ask for Brea, she will be more than happy to answer any questions and tell you about her experience having this eye opening procedure at OMNI, and yes, pun intended.
