Study of artificial cornea transplantation by using collagen cross-linking for corneal thinning disease

We studied changes of corneal property by UV-A collagen crosslinking, in order to develop artificial corneal stroma as a final goal. We attempted to establish a rating system using a rheometer, but reproducibility was insufficient. In a rabbit study of angiogenesis by suture neovascularization model, there was no difference between cross-linked eye and control. In a rabbit study to compare epithelium-on crosslinking with epithelium-off by anterior segment OCT, we found the level of demarcation line was shallow in epithelium-on eyes.
