Keratoconus is a progressive eye condition that affects the cornea, causing it to thin and bulge into a cone-like shape. This irregular shape can lead to distorted vision and increased sensitivity to light and glare, making daily activities challenging. At Newsom Eye, we specialize in diagnosing and managing keratoconus and offer advanced treatment options such as corneal cross-linking (CXL) to help patients maintain better vision and quality of life.

What is Keratoconus?

Keratoconus occurs when the cornea, which is normally dome-shaped, begins to thin out and bulge. This irregularity can severely affect vision, as it leads to an increase in myopia (nearsightedness) and irregular astigmatism. Symptoms of keratoconus can include:

  • Blurred or distorted vision
  • Increased light sensitivity
  • Difficulty with night driving
  • Frequent changes in eyeglass prescriptions
  • Eye strain or discomfort

The exact cause of keratoconus is unknown, but genetic factors and certain environmental influences may play a role. Early detection is essential for effective management, which is why regular eye exams are crucial, especially if you have a family history of the condition.

How Corneal Cross-Linking (CXL) Works

Corneal cross-linking (CXL) is a minimally invasive procedure designed to strengthen the corneal tissue, helping to halt the progression of keratoconus. The treatment involves applying riboflavin (a type of vitamin B2) eye drops to the cornea, followed by controlled exposure to ultraviolet (UV) light. This combination activates a biochemical reaction that creates new bonds, or “cross-links,” within the collagen fibers of the cornea. These cross-links help to stabilize the cornea and prevent further thinning and bulging.

Types of Corneal Cross-Linking

There are two primary types of CXL:

  1. Epi-Off Cross-Linking: In this procedure, the outer layer of the cornea (the epithelium) is removed to allow better penetration of the riboflavin solution. This approach is typically more effective for advanced cases of keratoconus.
  2. Epi-On Cross-Linking: With this method, the epithelium is left intact. While it may result in less discomfort and a shorter recovery time, it might not be as effective for advanced cases. Epi-On CXL may be an option for patients with early-stage keratoconus or those unable to tolerate the more intensive Epi-Off approach.

Your ophthalmologist at Newsom Eye will help determine which type of CXL is best suited to your needs based on the severity of your keratoconus and other individual factors.

Benefits of Corneal Cross-Linking for Keratoconus

Corneal cross-linking offers several benefits for patients with keratoconus:

  • Stabilization: The main goal of CXL is to prevent keratoconus from worsening, which can preserve the patient’s current level of vision and reduce the need for a corneal transplant in the future.
  • Minimally Invasive: CXL is a relatively quick procedure, usually taking about an hour, and is performed on an outpatient basis.
  • Improved Vision: While CXL may not completely restore vision, many patients experience less visual distortion and find it easier to wear contact lenses.
  • Long-Term Benefits: Studies show that CXL can effectively halt keratoconus progression, making it an essential treatment option for long-term eye health.

What to Expect During and After CXL Treatment

CXL is typically performed in a single session. During the procedure, your eye will be numbed with anesthetic eye drops to ensure comfort. Following treatment, it is normal to experience mild discomfort, sensitivity to light, and blurred vision for a few days. Most patients are able to return to their regular activities within a week.

Are You a Candidate for Corneal Cross-Linking?

If you’ve been diagnosed with keratoconus, it’s important to discuss CXL as a treatment option with your eye care provider. Candidates for CXL are generally individuals with:

  • Progressive keratoconus or ectasia following refractive surgery
  • Corneal thickness suitable for the procedure
  • Minimal or no scarring of the cornea

At Newsom Eye, our team will perform a comprehensive evaluation to determine if CXL is the right option for you. Our experts are dedicated to providing the highest quality care and the latest treatment options for keratoconus, so you can maintain the best vision possible.
