3. CORNEAL CROSS-LINKING Corneal cross-linking is a treatment for an  EYE problem called  KERATOCONUS

4. TYPES OF CROSS-LINKING Epithelium-off cross-linking.  In this procedure, the thin outer layer (epithelium) of the cornea is removed to allow the liquid riboflavin to more easily penetrate the deeper corneal tissue. Epithelium-on cross-linking . In this procedure (also called transepithelial cross-linking), the protective corneal epithelium is left intact.

5. Procedure and process Eyedrop   medication  and ultraviolet (UV) light are used to make the tissues in your cornea stronger. The goal is to keep the cornea from bulging more. It’s called “cross-linking” because it adds bonds between the collagen fibers in your eye. They work like support beams to help the cornea stay stable. specially formulated riboflavin (vitamin B2) eyedrops, which allow your cornea to better absorb light. It takes about 30 minutes for the drops to soak into your cornea.

6. Who Should Get Corneal Cross-Linking? Every victim of keratoconus. Best at the early stages when cornea not severely irregular

8. WHAT IS KERATOCONUS AND ITS CAUSE? This is the outward bulging of the cornea from its dome shape into a cone-like shape.

9. Causes Keratoconus is caused by a decrease in protective antioxidants in the cornea which leads to weakness in collagen fibers. Commonly starts at the age of 10 years and NOT GENETIC BUT RUNS IN FAMILIES.

10. DIAGNOSING KERATOCONUS As the cornea changes from a ball shape to a cone shape. A sudden change of vision in one eye double when looking with just one eye Objects both near and far looking distorted Being uncomfortable driving due to blurry vision, especially at night Performing a cornea topography
