Stress-strain measurements of human and porcine corneas after riboflavin–ultraviolet-A-induced cross-linking

This is the authors' abstract. We don't add key points for this paper.

Riboflavin-UVA-induced collagen cross-linking led to an increase in mechanical rigidity in porcine corneas and an even greater increase in human corneas. As collagen cross-linking is maximal in the anterior 300 microm of the cornea, the greater stiffening effect in human corneas can be explained by the relatively larger portion of the cornea being cross-linked in the overall thinner human cornea.
