It sounds insanely cool! They already managed it on a live rabbit eyeball apparently, now for an actual live rabbit. But honestly, I’m not really sure what could go wrong if a live eyeball works. It’s a pretty mechanical change, not much else in the body (if anything) is affected.

I guess the big thing would be refining the method for accuracy and then scaling up so that many people can get the treatment at ab affordable price point. Though I suppose if the platinum lens is basically the “correct” eyeball shape, it just needs to be sized correctly w.r.t. the size of your eyeball. That sounds like you could make a whole bunch of templates for different eye sizes, and then reuse them for everyone with that size?
