Lying still during the treatment is another common concern. The bed of the laser has a contoured headrest with an indent, which allows the back of your head to rest securely, but comfortably in place. During the treatment itself, the doctor will gently hold your head in position to keep you steady. He also uses a focusing mechanism to assure that the treatment is precisely centered. Your job is simply to watch a blinking target light. While you are doing this, the laser's computer will also be using its tracking system to monitor the position of your eye. The eye tracker adjusts the laser treatment to follow the small movements everyone's eyes make during the procedure.
