What is Keratoconus?

Keratoconus is a chronic, progressive ectasia (weakening of the cornea), causing corneal steepening (forming a cone shape), visual distortion, corneal thinning, and corneal scarring. This condition causes irregular astigmatism leading marked visual impairment.

The disease typically affects both eyes, although only one eye may be affected at the onset, and it can be asymmetric. Early in the disease, there may be minimal or no symptoms, whereas in advanced keratoconus there can be profound visual loss, eventually requiring a corneal transplant.

Why Choose Corneal Cross-linking as a Treatment for Keratoconus?

KCN 1

Corneal cross-linking is a minimally invasive FDA-approved outpatient procedure designed to treat progressive keratoconus (and other conditions that cause a similar weakening of the cornea). The two-step procedure involves application of riboflavin solution to the eye that is activated by illumination with UV-A light for under 30 minutes. The corneal cross-linking procedure strengthens and stabilizes the cornea, which recovers and preserves some of the cornea's mechanical strength. The corneal epithelium (the outermost layer of the cornea) is generally removed to increase penetration of the riboflavin into the stroma (the thickest tissue layer of the cornea). This procedure is known as the Dresden (epithelium-off) protocol.

Corneal cross-linking is most effective if it can be performed before the cornea has become too irregular in shape or there is significant vision loss from keratoconus. If applied early, cross-linking typically will stabilize or even improve the shape of the cornea, resulting in better visual acuity and an improved ability to wear contact lenses. Patients with a diagnosis of keratoconus, or if there is suspicion for the disease, must see one of our fellowship-trained corneal specialists and undergo clinical testing to determine if they are a candidate for the procedure.

Expert Keratoconus Care in Phoenix: What to Expect After Corneal Cross-Linking

When it comes to managing progressive corneal conditions like keratoconus, experience matters. At Horizon Eye Specialists, our Phoenix keratoconus specialists bring advanced training and years of experience in managing progressive corneal conditions, offering a full spectrum of diagnostic and therapeutic options to preserve your vision. Patients receive personalized care plans that take into account the stage of the disease, lifestyle needs, and long-term eye health.

Following corneal cross-linking, vision tends to stabilize over several weeks to months. While the goal of the procedure is to halt progression, some patients also experience improvements in visual clarity. During recovery, our clinical team ensures you are supported with clear aftercare instructions and timely follow-up to monitor healing and visual outcomes.

In more advanced cases, where significant scarring or distortion has already occurred, corneal transplantation surgery in Phoenix, AZ, may become necessary. This procedure replaces damaged corneal tissue with healthy donor tissue and can restore a level of functional vision when other treatments are no longer effective.

From early diagnosis to advanced interventions, we’re committed to your lifelong eye health. Schedule a consultation with our Phoenix keratoconus specialists today to explore your treatment options.

Frequently Asked Questions About Keratoconus & Corneal Cross-Linking in Phoenix, AZ

What are the early signs of keratoconus?

+

Early symptoms of keratoconus include blurry or distorted vision, frequent changes in eyeglass prescriptions, eye strain, and increased sensitivity to light. Since keratoconus develops gradually, early evaluation by a Phoenix keratoconus specialist is crucial to slowing progression.

Am I a candidate for corneal cross-linking?

+

You may qualify for CXL in Phoenix if you have progressive keratoconus and adequate corneal thickness. Our Phoenix-based keratoconus specialists use advanced imaging and diagnostic tools to determine if this treatment is right for you.

How long is the recovery after corneal cross-linking?

+

Most patients recover within a few days, though temporary light sensitivity or mild discomfort may occur. Full visual stabilization can take several weeks, with regular follow-ups with our eye care team to track progress.

Will I still need glasses or contact lenses after treatment?

+

Yes, many patients still require glasses or rigid gas-permeable contact lenses after corneal cross-linking. While the procedure helps to stabilize the cornea, it does not eliminate the need for vision correction. Some patients even find their contact lens fit improves after treatment.

What happens if keratoconus is too advanced for cross-linking?

+

In advanced cases, corneal transplantation surgery in Phoenix, AZ, may be recommended. This procedure replaces damaged or scarred corneal tissue with healthy donor tissue to restore vision. Our fellowship-trained corneal specialists will help determine if a corneal transplant is the next step for you.

Is corneal cross-linking covered by insurance?

+

Coverage depends on your insurance provider and policy. Our office team will verify your benefits and provide detailed information about any out-of-pocket costs before scheduling your keratoconus treatment in Phoenix, AZ.
