>>Any refractive laser procedure works because it ablates corneal tissue, reshaping and therefore thinning the cornea. This corneal tissue is removed forever, it does not grow back.<<
Blindside you are correct. However, the LASIK procedure ablates no more than 10% of the thickness of the corneal tissue where the RK cut as deep as 90% of the corneal thickness. I don't think you have to be an engineer to figure out which procedure will leave your eye much less susceptable to injury.
