What is LASIK?
One of the most popular ways to correct vision is with a procedure called LASIK (laser in-situ keratomileusis), which uses a laser to change the curvature of the cornea (outer window of the eye). LASIK has quickly become the procedure of choice for most patients because they recover quickly and have fewer side effects and complications than with other methods of vision correction. In fact, most LASIK patients notice a significant improvement in their vision soon after surgery. LASIK removes tissue within the cornea to treat low to moderate levels of nearsightedness, farsightedness and astigmatism.

How long does it take? Is it painful?
LASIK is a quick, virtually painless procedure. It is done using eye drop anesthesia, and while you may feel pressure, the technique is generally not painful. First, the Intralase or femtosecond laser makes a protective flap in the outer layer of the cornea, at about twenty-five percent of its depth from the surface. Next, the Excimer laser sculpts the internal corneal tissue to the correct refractive power by changing the curvature of the exposed corneal tissue. The corneal flap is laid back in its original position and allowed to dry for several minutes. 
Due to the cornea's extraordinary natural bonding qualities, stitches are usually not required. Although the vast majority of patients see 20/20 or better postoperatively, individual results cannot be guaranteed. The surgery is performed on an outpatient basis and most people return to work witihin one to three days. As with any surgical procedure, side effects and complications may occur.

Who are candidates for the LASIK procedure?
There are 290 million candidates for LASIK around the world. If you are 21 years of age or older and wear glasses or contact lenses to correct nearsightedness, farsightedness, astigmatis or mixed astigmatism, you may benefit from LASIK, but a thorough exam with your eye doctor will determine if this is the answer for you.
