This isn't really an answer to your question because I don't actually know what's next for laser eye surgery, and this is still FAR off in the future, but I recall reading about "cybernetic" contact lenses which would eventually allow humans to have night- and far-range- viewing. Theoretically, then, these kinds of technology could EVENTUALLY be implanted in the eye. Considering that technology exists already to allow blind people to see, I definitely think this is all possible.
