Dear Lord! I would hope that they couldn't get that out. Putting lasers directly into your eye sounds like a perfect recipe for large scale disaster. I don't care how many people say it's safe or how many papers there are out there on it, all it takes is a few microseconds of error just once in your whole life and it's boom lights out forever.
