Keratoconus is a disease of the cornea in which a normally round, dome-shaped cornea progressively thins, causing a cone-shaped bulge to develop.

Corneal cross-linking has indeed emerged as a significant advancement in the management of keratoconus. By strengthening the cornea through the creation of new collagen bonds, it aims to halt or slow down the progression of the disease.

The procedure you described involves the application of a photosensitizing solution, followed by exposure to ultraviolet light, which promotes the cross-linking of collagen fibers.
