Corneal Collagen Cross-Linking (CXL) Can Restore Your Vision

CXL is a procedure that uses riboflavin drops combined with ultraviolet light to strengthen the cornea. The procedure is designed to stop further progression of corneal ectasia (or thinning), which is typically seen in patients with keratoconus and in patients who have had LASIK or RK eye surgery. CXL is sometimes combined with other keratoconus treatments, such as scleral or other specialty contact lenses, intrastromal ring implants, or conductive keratoplasty.

Epithelium-Off and Epithelium-On Cross-Linking

There are two forms of CXL:

  • Epithelium-Off (Epi-Off)

    Epi-Off CXL involves removing the corneal epithelium and dropping a formula of riboflavin solution on the cornea for a period of time followed by controlled ultraviolet light exposure.

  • Epithelium-On (Epi-On)

    The Epi-On procedure uses a different concentration of riboflavin solutions and different exposure time with ultraviolet light, and does not involve the removal of the corneal epithelium.

We have a passion for treating keratoconus.

Properly and effectively treating keratoconus is a time-consuming process, and thus many doctors are not willing to spend the requisite time. Our team of experts stay current on the latest keratoconus management and treatment options and have the expertise, experience and compassion needed to restore your vision.

Are You a Good Candidate for CXL?

CXL is most effective in patients before the cornea has become too irregular in shape. If CXL is performed early enough, the procedure can halt the progression of keratoconus, and in some instances can even improve the shape of the cornea.

Restored vision is now possible for keratoconus patients who are:

  • Seeking treatment for the first time
  • Currently wearing contact lenses that are not comfortable or do not provide improved vision
  • Considering medical treatments such as CXL or conductive keratoplasty (CK)
  • Considering surgeries such as corneal transplants or corneal implants (Intacs)
  • Suffering from CXL, Intacs, or corneal transplant complications
