During corneal CrossLinking, 95% of UVA energy is absorbed by only 350 microns of Riboflavin soaked Cornea (fig17) As long as the treated cornea has a minimum thickness of 400 microns (after removal of epithelium), the corneal endothelium will not experience damage, nor will deeper structures such as lens and retina. Riboflavin (vitamin B2) is important for body growth, red blood cell production and assists in releasing energy from carbohydrates Its food sources include dairy products, eggs, green leafy vegetables, lean meats, legumes, and nuts Breads and cereals are often fortified with riboflavin Under the conditions used for corneal collagen crosslinking, riboflavin 5’phosphate, vitamin B2, functions as a photoenhancer which enables the crosslinking reaction to occur.
