How Does LASIK Work

How Does LASIK work?

If you’ve ever thought about the procedure, you might consider how does LASIK work?  Davis Eye Center is here to answer all of your questions.  LASIK, also known as Laser-Assisted In Situ Keratomileusis, is a minimally invasive refractive eye surgery. We use this procedure to treat patients who experience nearsightedness, farsightedness, or have astigmatism.

During the LASIK procedure the doctor uses, you guessed it, a laser. First, Dr. Davis creates a thin flap in the outer layer of the cornea in order to get to the tissue underneath. Then, we use the laser to reshape the tissue under the corneal flap so it can properly focus light. Lastly, the flap is placed back over the eyeball and will typically reheal itself within a day or two. All in all, the entire LASIK procedure typically takes less than 30 minutes.

How to Prepare for the LASIK Procedure

On the day of your LASIK procedure, be sure to arrange transportation to and from your appointment. Due to the nature of the procedure, you won’t be able to drive yourself.  The LASIK procedure typically lasts less than 30 minutes from start to finish. The best part? This all happens while the patient (you) is relaxing on their back in a chair.
To get started, the doctor will begin by placing numbing drops into your eye and may give you some medication to help relax.

Once the numbing drops are given a few seconds to take effect, the doctor will place a lid speculum on your eye to keep it open. Next, the doctor will use a marker to identify your cornea and then apply a suction ring on your eye to prevent movement. A slight feeling of pressure and/or dimmed vision may occur while the ring is in place. While focusing on a target light to steady your eye, the doctor will create a thin, hinged flap on the cornea with a microkeratome or a femtosecond laser.

After folding back the hinged flap, the doctor will use an excimer laser to reshape your cornea.

Cornea Reshaping | How Does LASIK work?

During the reshaping process, you may hear a clicking noise or smell a slight burning odor as the laser reshapes your corneal tissue. This is completely normal. The corneal flap is then laid back in place and Dr. Davis will smooth it over. As a result, acting as a barrier to help protect the cornea as it heals since no stitches are involved in the process.

What Will Happen? | How does LASIK Work

Though we consider LASIK to be a minimally invasive procedure, it is important to remember that your eyes will require some time to heal.

Many patients experience a slight itching, burning or discomfort immediately after the procedure. It is extremely important to remember to not rub your eyes as this could cause damage to the corneal flap. You will be given an eye shield to be placed over your eye as protection. This shield should be worn the first couple of days after the procedure to prevent you from rubbing your eye while you sleep and accidentally getting hit or poked as your cornea heals.

The doctor may also prescribe eye drops to be taken to prevent infection or inflammation and artificial tears to help lubricate the eye. Within 24-48 hours after surgery, a follow-up visit with your doctor will be scheduled to monitor your progression. Multiple follow-up visits over the following months will also be conducted to ensure vision stabilization.

Generally, we advise waiting 24-72 hours after surgery before beginning any non-contact sports. It is highly encouraged to speak with your doctor before resuming any activity as each patient will experience variable healing times.
