For some patients, Laser Assisted In-Situ Keratomileusis
(LASIK) is the best way to achieve natural vision. LASIK
was first performed in 1989 by an ophthalmologist in Greece and
was introduced to American surgeons in 1990.
Prior to the LASIK procedure, some drops are placed on the eye to numb the cornea. The entire treatment takes only about 15 minutes.

The physician utilizes a special instrument (called a microkeratome) to make a very fine layer through about one third of the front surface of the cornea. This makes a "flap" of clear tissue on the central part of the eye. The resulting "flap" is approximately 160 microns thick (about 1/3 the thickness of human hair) and about 9 millimeters in diameter (much wider than the pupil).

Once
this flap is created, the surgeon removes the microkeratome and
gently folds the flap, exposing the underlying corneal tissue.
|
|
The
excimer laser is then applied to alter the curvature of the cornea
to achieve the desired optical correction.
|
|
After
the laser has been applied for the correction of myopia, or nearsightedness,
the profile of the treated area of the cornea will be flattened.
|
|
Upon
completion of the application of the laser, the flap is gently
laid back into its original position over the treated corneal
tissue. Because of the natural bonding qualities of the cornea,
there are no stitches required for your treatment.

After your treatment, an eye shield will be applied to help protect the eye from accidental bumping or rubbing. During the first 24 - 48 hours, you may experience a mild "something in the eye" sensation. Most patients are able to pass a driver's test without their glasses within the first couple of days after their treatment.
There are a number of factors that might make you a good or poor candidate for LASIK. These include: your prescription, the health of your eyes, the thickness of your corneas, the size of your pupils, the health and integrity of your tearfilm, and MOST IMPORTANTLY THE SPECIFIC LIFESTYLE NEED YOU WISH TO ACCOMPLISH through the elimination or your dependence on glasses or contacts.
The best way to determine whether you are a candidate for Laser Vision Correction and specifically, a candidate for LASIK, is to have a thorough examination and consultation so that the necessary diagnostic testing can be performed and all of your questions can be answered.
