It is not uncommon for patients to move their eye during the procedure. A little movement does not cause any undue risk or danger to your eye, and our surgeons can stop the laser at any time during the procedure. He will ask you to concentrate on a red light. If you move your eye too much, the laser will automatically shut down. After you are in position again, our surgeons will restart the laser, and it picks up where it left off. The laser is also able to track eye movements.
