Tracking means it helps the laser follow any eye movements.
For some people this is the only way to have laser vision correction. If they can't hold their eye still, the tracker just follows the eye and makes sure every laser pulse is put in an accurate location. For some patients who can hold their eye still, the tracker gives them great peace of mind that they do not need to worry about eye movement. We tell you in your exam whether or not we feel you should have a laser treatment with tracking. You do not feel anything different the tracker just follows your eye.
