What Happens If I Look Away, Blink, Cough Or Sneeze During Laser Eye Surgery?
If the patient moves, looks the other way or suddenly blinks, the Laser Eye Surgery and the procedure will not be harmed. We have many systems in place, including an eye tracking system, which means that if the patient moves, coughs, if they sneeze, or even fall off the bed, it will not change the results.
Although your eye will move during surgery, eye-tracking technology ensures your safety when this happens. Compensating for eye movement is a key factor in ensuring that the laser pulses in to exactly the right place. There are different methods (video infra-red, 3D, LADAR), all of which involve detecting the position of your eye. There is a minor lag between the laser noticing your eye has moved and compensating for that movement. All trackers, to date, provide approximately the same level of delay time – most operate with a delay of less than ten milliseconds (one hundredth of a second).
Professor Dan Reinstein explains that looking away, blinking, coughing or sneezing during the procedure does not affect the results of Laser Eye Surgery.

“It’s a cliche but this really has changed my life! My only regret is I didn’t do it sooner! There was no pain during the procedure or after and my eyesight now is better than when I wore contact lenses! It’s amazing to wake up in the morning and be able to see without trying to find my glasses!” -Fiona Davis.Go back
