LASIK Laser Eye Correction

LASIK (Laser In-Situ Keratomileusis) is an increasingly popular laser eye correction method used to correct nearsighted, farsighted, and astigmatism issues. LASIK, like other laser procedures, works to correct vision by reshaping the cornea, the clear front area of the eye, allowing light to travel more efficiently through the eye to refocus onto the retina in the rear of the eye.

During LASIK laser eye surgery, a patient is placed under local anesthesia with a mild sedative, as an eye surgeon uses a precise instrument called a "microkeratome" to cut a flap in the cornea. The cornea is then pulled backward, exposing the underlying corneal tissue. Next, an excimer laser is used to reshape the cornea and the flap is put back into place finishing the procedure. The entire process takes approximately ten minutes to complete.

Following LASIK laser eye correction surgery, normal activities, especially driving, should be avoided. While healing does occur quickly, some people may have blurry or hazy vision for the first day or two. Many patients note improved vision within in just a few days. Eyes will be dry, although they may not feel as though they are, and doctors will prescribe special eye drops to help lubricate the eyes and prevent the chance of infection. The eye drops may cause a slight burning sensation and may blur vision when they are first instilled. Follow up visits are typically scheduled within 24-48 hours after the procedure. Regular visits to an eye doctor or surgeon to monitor progress occur for the next six months as well.

While side effects are rare, and there has been no evidence of long-term side effects following LASIK treatments, there are a few short-term effects that should be noted. The effects include: halo effects, glare, dry eyes, fluctuating vision, and difficulty driving at night. These effects are usually temporary and resolve themselves.

There are several advantages and disadvantages that should be considered when deciding to undergo LASIK laser eye correction. Advantages include: clear vision without the need for glasses or contact lenses; very little pain or discomfort; almost instantaneous vision improvement; the procedure is minimally invasive and requires no stitches or bandages; and modifications can be made in coming years to further improve vision. Disadvantages include: the procedure is relatively expensive with an estimated cost of between $2,000 and $2,500 per eye; corneal changes cannot be reversed following the procedure; further LASIK treatments may be needed; glasses or contact lenses may still be needed for perfect vision; and although rare, flap complications can cause permanent damage.

As with any surgical procedure, LASIK laser eye correction should be thoroughly discussed with a skilled optical professional, all of the options considered, and the risks carefully weighed.
