Dr. Abraham Zlatin does CRT, which reshapes the cornea while you sleep. No cutting up the eye as with laser surgery. Sounds interesting. I’ve thought of having Lasik, but I don’t like the idea of lasers messing with my eyes. It would be nice to be able to get around without contacts, though! A video on YouTube shows the idea.
Wikipedia has an article about Orthokeratology.
Another non-surgical vision correction method is Ortho-C.
