Hi i want to know when you have lasik eye surgery, during the sugery what if my eyeball moves is that ok, or do i have to keep it still.

Do not worry : The movement of your eye is controlled by the surgeon during the procedure and you will not have to worry about it.

Lasers have tracking: During the procedure you will be watching a fixation light. Most of the excimer lasers used in this country have tracking devises. At the start of the procedure your surgeon will align the tracker. If your eye moves a small amount, the laser will move with you. If you move a large amount, the laser will merely shut off until you are looking at the light again.
