A particular problem in treating keratoconus by means of crosslinking is that the irregular cornea does not allow a homogeneous treatment profile over the treated area in conventional crosslinking. This is because the amount of treatment energy transferred to the cornea depends on the local steepness. This steepness varies, however, from point to point and from cornea to cornea. The higher the local steepness the lower the treatment effect. Unfortunately, the steepness of the cornea is the highest in the most affected area by the disease which is exactly the opposite of what should be. This problem is solved by KERALUX which permits a constant energy transfer to each point of the treated cornea - independent from the inter- and intraindividual variation of the local steepness.

The following video shows how KERALUX treatment is performed and what is the advantage over conventional crosslinking.
