 Frequently Asked Questions about LASIK Surgery

John French, MD, Corneal, Cataract, LASIK, Specialist

How does LASIK Work?

The concept of corneal refractive surgery is to change the shape of the cornea so that images seen will be focused on the retina.  LASIK was developed to give faster results with less discomfort.  A thin flap of corneal tissue is created, gently lifted and an excimer laser treatment is applied to the cornea below.  The flap is placed back over the treated cornea.  Originally, a blade was used to make this flap but the femtosecond laser has almost entirely replaced the older blade method.  Both surgical options, PRK and LASIK, have their advantages and applications.  The surgeon determines the most appropriate procedure for each patient during the pre-operative evaluation based on the glasses prescription, corneal tissue thickness and other factors.

I have an astigmatism can I still get LASIK?

Excimer lasers also can correct astigmatism by reconfiguring the corneal shape to create a more  normal shape. It is a misconception that LASIK cannot treat astigmatism.

What to expect before LASIK Surgery?

Your eye doctor will perform a thorough eye exam to ensure your eyes are healthy enough for the procedure. They will evaluate: the shape and thickness of your cornea; pupil size; refractive errors (myopia, hyperopia and astigmatism); and check for any other eye conditions.

Your eye doctor will also note your general health history to determine if you are a suitable candidate for LASIK.  You should stop wearing contact lenses for a period of time advised by your doctor (typically around two weeks) before your eye exam and before the LASIK procedure.

What to expect the day of Surgery?

Lasik is a two-step vision correction procedure performed on the cornea.  At Carolina Eye Associates, the procedure is an all laser procedure. The Wavelight FS 200 Femtosecond Laser creates a thin flap of the cornea in the first step. The Allegretto WAVE Eye Q excimer laser then reshapes the central cornea before the flap is replaced.

Before the LASIK procedure begins you will receive a series of anesthetic drops in each eye.    At Carolina Eye we use the Allegretto Wave Eye Q laser which is one of the fastest and most precise excimer laser systems available in the United States, treating one diopter of correction in only 4 seconds.  The doctor will watch your eye through a microscope as the laser sends pulses of light to your cornea.

The laser light pulses painlessly reshape the cornea.  LASIK is performed on each eye separately, with each procedure taking only about one minute.

What is the recovery process?

Many people sit up right after surgery and notice better vision.  Still, complete recovery can take time and much of the responsibility will be in the patient’s hands.  Your eyes heal and adapt with surprising speed, but you can help the process along by closely following your surgeon instructions.   As your eyes heal and your vision stabilizes, you can wind up with impressive results.
