Understanding Keratoconus and the Benefits of iLink® Corneal Cross-Linking

Vision is one of your most vital senses, and protecting it starts with understanding the conditions that can threaten it. At Greenwich Ophthalmology Associates, we are committed to providing patients with the most advanced treatments available, including iLink® corneal cross-linking for keratoconus.

If you or a loved one has noticed changes in your vision, we’re here to guide you with expert care and innovative solutions designed to preserve and protect your sight.

What Is Keratoconus?

Keratoconus, often abbreviated as KC, is a progressive eye disease where the cornea—the clear, dome-shaped surface at the front of the eye—becomes thin and bulges into a cone-like shape. This distortion can cause significant visual disturbances such as blurry vision, difficulty with night driving, frequent prescription changes, and increased light sensitivity. If left untreated, keratoconus can severely impair vision and may ultimately require a corneal transplant.

Most commonly appearing in late teens or early adulthood, keratoconus affects both eyes, although not always symmetrically. It impacts individuals of all ethnicities, with slightly higher incidence in Asian, Black, and Hispanic populations. Genetics may also play a role, with about 10% of patients having a family history of the disease.

Introducing iLink® Corneal Cross-Linking

Greenwich Ophthalmology Associates proudly offers iLink® corneal cross-linking—the first and only FDA-approved treatment designed to slow or halt the progression of keratoconus. iLink ® is a minimally invasive outpatient procedure that strengthens the cornea using a combination of specially formulated Photrexa® riboflavin eye drops and ultraviolet (UV) light from the KXL® System .

By creating new bonds between collagen fibers, iLink® enhances corneal stability, helping preserve vision and reduce the risk of needing a corneal transplant. Recognized worldwide as the standard of care for progressive keratoconus, iLink® represents a significant advancement in treatment options.

How the iLink® Procedure Works

The iLink® procedure begins with the application of Photrexa® eye drops to the cornea. After the cornea is saturated, it is exposed to a precise amount of UV light. This combination induces the formation of new cross-links within the corneal collagen, resulting in a stronger, more stable corneal structure.

Patients benefit from:

A minimally invasive outpatient experience

A short procedure lasting about an hour

No need for general anesthesia

A proven method to slow disease progression

Most importantly, iLink® can help preserve vision, empowering patients to maintain their daily activities with greater clarity and confidence.

Insurance Coverage and Accessibility

Today, more than 95% of commercial insurance plans in the United States cover the iLink® procedure, recognizing its medical necessity . Our knowledgeable team is here to assist patients with understanding their insurance benefits and to ensure a seamless care journey.

Is iLink® Right for You?

If you or a loved one has been diagnosed with progressive keratoconus or corneal ectasia following refractive surgery, iLink® corneal cross-linking may be an ideal treatment option. Early diagnosis and intervention are key to preserving vision and minimizing the need for more invasive procedures in the future.
