The LASIK Vision Correction Procedure

Watch Video

LASIK vision correction is a type of refractive surgery designed to reshape the cornea and produce clearer vision. Used to treat hyperopia, myopia, and astigmatism, LASIK is performed by an ophthalmologist and is an outpatient procedure. Learn more about what happens during the procedure by reading the sections below.

What Happens During LASIK Surgery

After you have finished preparing for LASIK vision correction, a LASIK surgeon will perform another eye exam and answer lingering questions or concerns. The procedure itself takes less than 15 minutes, although the length of pre- and post-operative examinations varies depending on the doctor and the individual case.

Refractive Error Measurement

If you choose to undergo custom LASIK vision correction rather than traditional LASIK, the procedure will begin with the mapping of the eyes with Wavefront™ technology. This provides a blueprint of your eyes’ lower and higher order aberrations, allowing for the most accurate correction of visual impairments. The treatment then proceeds in a similar manner to traditional LASIK.

Traditional LASIK vision correction patients also undergo a pre-LASIK eye exam. The patient’s eyes will be measured and the surgeon will once again review the procedure, making sure all questions and concerns have been addressed.

Creating the Corneal Flap

To begin the traditional LASIK vision correction procedure, the eye will be anesthetized with topical eye drops. The patient will be asked to lie on a table with laser equipment mounted above it. The eye will be held open with a special instrument, a speculum. The other eye is protected by a shield. As the patient stares at a small blinking light, the LASIK surgeon will use a microkeratome or the Intralase® laser to create a hinged corneal flap on the outer layer of the eye.

Reshaping the Cornea

After the flap has been created, an excimer laser is used to remove the precise amount of corneal tissue needed to correct your refractive error. As the LASIK vision correction patient continues to stare at the blinking light, the LASIK surgeon then will apply very small, rapid bursts of the laser, reshaping the cornea. This portion of the procedure only takes about 15 seconds per eye.

Replacing the Flap

Once the cornea has been reshaped, the flap is replaced. The eye will heal by itself and no stitches are necessary. The actual surgery usually takes less than 15 minutes, but preoperative preparation may extend LASIK vision correction surgery time to one hour.
