Most patients have some nervousness about laser vision correction, and this is certainly understandable. In speaking to thousands of patients I have come to learn that the greatest anxiety concerns their ability to look properly at the target during the treatment. In the early days of LASIK this was extremely important as it was only the patient who controlled where the treatment was applied based on their fixation. With more modern technology, we only need the patient to look in the approximate location of the fixation light, and the laser has one or more eye trackers which take over like an autopilot and guide the treatment to the appropriate location. Knowledge of the fact that the patient can do less than a perfect job of looking and still potentially get a perfect treatment makes most patients feel much more comfortable about the experience.
