Intraocular Collagen Cross-Linking for Keratoconus

Responsive image

Keratoconus is a progressive eye condition that causes the cornea to thin and bulge into a cone shape. This can lead to vision problems, including blurred vision, astigmatism, and light sensitivity.

Intraocular collagen cross-linking (CXL) is a minimally invasive procedure that can help to stop the progression of keratoconus and improve vision. CXL involves using riboflavin (vitamin B2) and ultraviolet (UV) light to strengthen the collagen fibers in the cornea.

How does CXL work?

CXL works by creating new bonds between the collagen fibers in the cornea. This makes the cornea stronger and more resistant to bulging.


What are the benefits of CXL?

CXL can help to:

  • Stop the progression of keratoconus
  • Improve vision
  • Reduce astigmatism
  • Improve contact lens tolerance
  • Reduce the risk of needing a corneal transplant

Who is a candidate for CXL?

CXL is a good option for people with keratoconus who have:

  • Thin corneas
  • Progressive keratoconus
  • Intolerance to contact lenses
  • Poor vision with glasses or contact lenses

What is the CXL procedure like?

The CXL procedure is typically performed in an outpatient setting under local anesthesia. The surgeon will first remove the corneal epithelium (the top layer of the cornea). Then, riboflavin eye drops are applied to the cornea and allowed to soak in. Next, the surgeon will use a UV light to activate the riboflavin. The UV light treatment lasts for about 30 minutes.

After the procedure, the surgeon will place a bandage contact lens on the cornea. The bandage contact lens will help to protect the cornea and promote healing.

What is the recovery from CXL?

Most people experience some discomfort and blurred vision after CXL. These symptoms usually improve within a few days. The bandage contact lens will be removed after about 3-4 days.

What are the risks of CXL?

CXL is a safe and effective procedure. However, there are some risks associated with the surgery, including:

  • Infection
  • Corneal scarring
  • Pain
  • Discomfort
  • Blurred vision
