Interesting issue. I have thought about this myself, even though I do not often approach violence in any way. I guess if you get beat up and a hook hits the eye, it will cause demage wether you have a native, healthy cornea or a graft grown into your eye with the epithelium layer as protection. Either way it will cause demage. It is, by the way, far more victims of violence with a healthy, untouched eyes that get cornea demage. As a matter of fact, many of them even have to have an emergency graft. And I guess, if some of us graftees are so unlucky to get a punch that demages the graft, they probably stitch on another one if the original is too much demaged to get back on place.
