Publication Exclusive: Contact lens-assisted cross-linking treats corneal ectatic disorders in thin corneas
Collagen fibers in the human body are normally bonded together and stabilized by covalent cross-links. The tensile strength of mature collagen fibers is largely due to intermolecular covalent cross-links. Collagen cross-linking was described by Theo Seiler et al as a means to strengthen a weak and ectatic cornea. This works by utilizing ultraviolet A at a wavelength of 370 nm in the presence of the photosensitizer riboflavin to create an increased number of covalent bonds among corneal stromal collagen fibers.Riboflavin is a photosensitizer and causes damage at a lower UVA (Read more...)
