What happens If you blink during LASIK?

One of the most common concerns we hear from patients is this:
“What happens if I blink during LASIK?”

It’s a fair question. LASIK sounds high-tech and precise, so the idea of blinking mid-procedure can make anyone nervous.

Here’s the short answer:
You don’t need to worry. Blinking during LASIK is not a problem.

In this post, we’ll explain why blinking isn’t a concern, how the procedure is designed to keep your eyes safe, and what the experience really feels like.

First things first: Your eyes are gently held open

Before the laser starts, your eye is numbed with drops. Then, we place a small, comfortable device that gently holds your eyelids open. You won’t feel the urge to blink because your eye is numb, and your lid can’t close.

It may sound strange, but most people say it’s less uncomfortable than expected. In fact, it’s often compared to feeling like you’re getting an eye exam.

What if you move your eye?

Today’s LASIK technology includes eye-tracking systems that monitor your eye movements up to 1000 times per second.

If your eye shifts even slightly, the laser will pause automatically until it’s perfectly aligned again. Then it resumes exactly where it left off.

This ensures precision and safety, even if your eye isn’t perfectly still the whole time.

You’ll focus on a small light

During the procedure, you’ll be asked to look at a blinking light. That’s your target. It helps guide your focus and lets the laser know where to reshape your cornea.

Don’t worry if you look away for a moment. The laser tracks and adjusts in real time. Your results will still be excellent.

You’ll be calm and supported

The procedure takes just a few minutes per eye. From start to finish, your surgeon and team are with you every step of the way. You’ll hear calming instructions and gentle guidance.

If you’re feeling anxious, we may also give you a mild relaxing medication beforehand. Most patients say it helps them feel at ease and in control.

Can blinking mess up the results?

No. With numbing drops, the eyelid holder, and the eye-tracking system, there’s no risk of blinking interfering with the results.

Modern LASIK is incredibly safe and accurate. The technology is built to account for natural reflexes like blinking or eye movement.

What does the laser actually do?

LASIK reshapes the surface of your cornea to improve how light focuses inside your eye. The laser removes tiny layers of tissue, measured in microns, to give you clearer vision.

It’s fast, precise, and personalized to your eyes.

What should I do instead of worrying?

Focus on preparing for a great result.

• Follow your pre-op instructions
• Rest before your procedure
• Ask any questions you may have
• Trust the technology and your surgeon.

Millions of people have had LASIK safely and successfully—and yes, they blinked too.

Life after LASIK

After surgery, most patients notice clearer vision within a day. Over the next few days and weeks, your sight sharpens even more.

You’ll enjoy life without glasses or contacts. No more foggy lenses, dry contacts, or worrying about where you left your glasses.
