It's one of the first questions we hear from almost every potential LASIK patient: "What happens if I blink or move during the procedure? Can I mess it up?"
Let's put that fear to rest. The short answer is: you can't.
Our advanced LASIK system is designed with multiple layers of safety to account for any involuntary movements. Here's how:
✔️ You physically can't blink because a small device gently holds your eyelids open.
✔️ Numbing drops suppress the urge to blink, so you stay comfortable.
✔️ Our laser's ActiveTrak 3D motion tracking monitors your eye 1,000 times per second.
✔️ If you move too much (or even sneeze!), the laser pauses automatically and resumes exactly where it left off once you're settled.
We've put all the details about our incredible safety technology — from Iris Registration to our bladeless flap creator — into a comprehensive guide on our blog. If you're even a little nervous about LASIK, this is a must-read.
