Patient Perspective on Cross-Linking

Learn more about the importance of early diagnosis and treatment from a keratoconus patient and her treating physician.

A General Overview

Corneal cross-linking is a minimally invasive outpatient procedure that combines the use of Photrexa® Viscous (riboflavin 5’-phosphate in 20% dextran ophthalmic solution), Photrexa® (riboflavin 5’-phosphate ophthalmic solution) and the KXL® system for the treatment of progressive keratoconus.

Corneal Cross-Linking:
  • Creates new corneal collagen cross-links
  • Results in a shortening and thickening of the collagen fibrils
  • Leads to the stiffening of the cornea

FDA Approval

The first and only therapeutic products for corneal cross-linking which have been FDA approved to treat progressive keratoconus.

In April 2016, the FDA approved Photrexa® Viscous (riboflavin 5’-phosphate in 20% dextran ophthalmic solution) and Photrexa® (riboflavin 5’-phosphate ophthalmic solution) and the KXL® System for corneal cross-linking, a minimally invasive outpatient procedure that combines the use of Vitamin B2 eye drops and ultra-violet (UV) light.

The approval of Photrexa Viscous, Photrexa and the KXL System offers an effective treatment for patients who, until recently, had no therapeutic options to limit the progression of this sight-threatening disease.

Ophthalmologists and optometrists play complementary roles in #eye care. #Optometrists provide primary vision care, diagnose & treat eye conditions, and fit contact lenses. #Ophthalmologists are medical doctors that can perform eye surgery, such as #crosslinking. @StephenCurry30
