What is Lasik?

LASIK is the most common surgical treatment to correct nearsightedness in the United States. The technique has been used successfully in the U.S. since 1991.

What It's Used For

LASIK can be used to treat the following vision problems:

If you have one of these vision problems, your eye doctor can help determine whether LASIK surgery is appropriate for you.


Once you decide to have LASIK eye surgery, your doctor will schedule an eye evaluation prior to surgery. If you wear contact lenses, you must switch to eyeglasses for a few weeks before this evaluation. This will allow your cornea to resume its natural shape.

At your presurgery eye evaluation, your eye doctor will review your medical history and eye history. To confirm that your vision is stable, he or she may ask to see your eye prescription records. Bring those with you to the examination.

Also, make a list of any medications you take. The list should include any over-the-counter drugs and herbal remedies. Your doctor will need to review this list.


How It's Done

Your doctor will ask you to stop wearing makeup, lotions and perfumes for a day or two before surgery. You will not be able to drive after your LASIK procedure. Make arrangements for someone to drive you home.

On the day of the procedure, your doctor may give you a mild sedative to help you relax. You will enter the operating room and lie down in a reclining chair.

The area around your eye will be cleaned with an antiseptic solution. Next, numbing eye drops will be placed in your eye so that you will not feel pain or discomfort during the procedure. An instrument called a lid speculum will be inserted into your eye to keep your eyelids open. The doctor will use special ink to mark the surgical area on your cornea.

Next, a ringlike suction device will be placed on the front of your eyes to hold your cornea in place during the procedure. This suction ring will cause a sensation of pressure, but no pain.

Then, a delicate cutting instrument called a microkeratome or a special cutting laser will be used to slice a tiny, hinged flap of tissue from the front of your cornea. You will not see or feel the microkeratome cutting your cornea.

Once the cutting is done, the surgeon will remove the suction ring from your eye, and fold back the hinged flap of cornea. Next, the laser will be moved into position, and you will be asked to stare at a light. Staring fixes your gaze and keeps your eye from moving.

Once your eye is steady, the doctor will use the laser to vaporize portions of your cornea. This vaporization is guided by a computer. It is based on precise eye measurements that were made during your presurgery examination. As the laser works, you will hear a clicking sound, and you may notice a smell similar to burning hair. These sounds and smells are normal.

When your laser treatment is finished, the doctor will reposition the hinged flap of cornea. No stitches are necessary. The doctor probably will cover your eye with an eye shield to protect the corneal flap as it heals.

You will be prescribed eye drops, which often include a topical corticosteroid and antibiotic. You likely will need someone to help you with the drops when you first get home. It's important to strictly follow your doctor's instructions. Schedule your appointment today at and start enjoying the vision you have always wanted.
