What Happens During LASIK?
LASIK is an outpatient procedure, meaning you will go to the surgery center, have the procedure, and go home the same day.
When you enter the surgery room, you will lie down, and numbing drops will be applied to your eyes to keep them comfortable throughout the LASIK procedure. A small device will be used to keep your eye wide open during all steps of the surgery.
Next, either a laser or a bladed surgical tool called a microkeratome will be used to create an ultrathin flap on the center of the cornea. With either method, the device is attached to the surface of your eye with suction, so you will feel slight pressure during this step.
(If you are having all-laser LASIK, two lasers are used: the corneal flap is created with a femtosecond laser, and the underlying corneal tissue is reshaped with an excimer laser.)
The flap is then folded back to expose the area of the cornea that will be reshaped with the laser.
Before being positioned over your eye, the excimer laser is programmed to deliver the exact amount of energy and treatment pattern to your eye for your specific vision correction needs.
The surgeon positions the laser directly over your eye and initiates the computer-controlled treatment, which usually takes less than a minute.

You will be asked to look at a target inside the laser, and your surgeon will be observing your eye through a microscope during the laser reshaping process.
When the laser treatment is completed, the corneal flap is returned to its original position. The LASIK procedure is then repeated on your other eye.
Usually it takes less than 15 minutes to perform LASIK surgery on both eyes.
