What happens if I move my eye during LASIK?

Berkeley Eye Center's VISX Star S4 IR laser uses ActiveTrak 3D motion tracking, which monitors your eye 1,000 times per second. If you move beyond the safe range, the laser pauses automatically and resumes exactly where it stopped once you've settled. No part of the treatment needs to restart.

No. Numbing drops and oral medication ensure you feel comfortable throughout . You may feel mild pressure during flap creation, but no pain. After the procedure, some temporary scratchiness or grittiness is normal and resolves within hours to a day.

How long does LASIK surgery take?

The actual laser treatment takes less than 60 seconds per eye. You'll be at the center for approximately two hours total, including preparation, the procedure itself, and your initial post-operative check.

Can I sneeze during LASIK?

Yes — and it won't affect your outcome. The laser's motion tracking system detects any sudden movement and pauses automatically, then resumes from exactly the same point once you're still again.

What age is best for LASIK?
