    To overcome the problems associated with performing collagen cross-linking in thin corneas, contactlens-assisted cross-linking allows attainment of 400-micron endothelial thickness via creation of an extra precorneal layer composed of a riboflavin-soaked contact lens and a thin subcontact lens riboflavin film, which together create an absorbtion medium in the precorneal space, artificially increasing the thickness.
