LASIK Wavescan

Plan on being at University Eye Institute East for approximately 60 – 90 minutes. Your doctor will guide you through all the steps associated with the procedure and answer all of your questions.

Reminders for the day

  • Wear comfortable, casual clothing. You will not have to change for the procedure.
  • Don’t wear any makeup, cologne or perfume.
  • Don’t take any medications which may make you drowsy. Check with the doctor to see if you should take daily medications you may have before or after surgery.
  • Bring your sunglasses. You may be light sensitive after the procedure.
  • Bring someone to drive you home.


Questions you might have

Will there be any pain?

You are given numbing eye drops, so you won’t feel any pain. You will feel the doctor’s hands around you face and some pressure, but it won’t hurt.

What will I see during surgery?

During the procedure, you will see a flashing light, which is the target at which you are instructed to stare. You’ll also see bright lights and shadows.

What happens if my eye moves during surgery?

The laser system has high-speed video imaging that can measure your eye up to 500 times per second. If your eye moves, the laser follows it.

How long will my surgery take?

The entire procedure takes only about 10 minutes per eye.


The Procedure

Anesthetic drops will be placed in each eye.

The doctor and his staff will position you on the laser table making sure you are comfortable. You will be asked to focus on a small blinking light. The first step is to create the flap with the femtosecond laser. The creation of the flap itself is quick and takes approximately 1 minute.

The laser table is then swiveled over to the Wavefront FS500 Excimer laser for treatment. Again, you will be asked to focus on a small blinking light. Pulses of laser energy precisely reshape your cornea. The corneal flap is then laid back into place and acts as a natural bandage to help your eye heal.
