Say Goodbye To Glasses & Contact Lenses!
For those whose eyesight can benefit from the LASIK procedure, the days of glasses and contact lenses are truly a thing of the past! For millions of people, the world has changed because they can now view it with the naked eye. The procedure can eliminate a lifetime of dependence on glasses and contact lenses and takes only a few minutes to perform.


The Cornea & Poor Vision

The cornea is a part of the eye that helps focus light to create an image on the retina. It works in much the same way that the lens of a camera focuses light to create an image on film. The bending and focusing of light is also known as refraction. Usually the shape of the cornea and the eye are not perfect and the image on the retina is out-of-focus (blurred) or distorted. These imperfections in the focusing power of the eye are called refractive errors. There are three primary types of refractive errors: myopia, hyperopia and astigmatism. Persons with myopia, or nearsightedness, have more difficulty seeing distant objects as clearly as near objects. Persons with hyperopia, or farsightedness have more difficulty seeing near objects as clearly as distant objects. Astigmatism is a distortion of the image on the retina caused by irregularities in the cornea or lens of the eye. Combinations of myopia and astigmatism or hyperopia and astigmatism are common. Glasses or contact lenses are designed to compensate for the eye's optical imperfections.


Step One - After your eye has been numbed with "eye drop" anesthesia, an instrument known as an eyelid speculum will be positioned to hold your eyelid open. You will remain awake and comfortable throughout the procedure.

Step Two - A small suction ring will be placed around the cornea and serves as a platform for the microkeratome.

Step Three - The microkeratome separates the surface layers of the cornea, and the corneal flap is folded back.

Step Four - You will be asked to look at a target light while the Excimer laser reshapes the corneal tissue. A clicking sound can be heard as each microscopic layer of tissue is vaporized. This process will last from seconds to minutes, depending on the amount of correction necessary.

Step Five - The corneal flap is then placed back into its original position and allowed to dry for a few minutes.

Step Six - You will be given additional eye drops, and your eye may be shielded for protection. Your vision will probably be a little blurry at first so have someone drive you home and relax for the rest of the day.


What is LASIK?

Surgical procedures aimed at improving the focusing power of the eye are called refractive surgery. In LASIK surgery, precise and controlled removal of corneal tissue by a special laser reshapes the cornea changing its focusing power.

LASIK stands for Laser-Assisted In Situ Keratomileusis, which simply means "to shape the cornea within using a laser," and is a procedure that permanently changes the shape of the cornea, the clear covering of the front of the eye, using an Excimer laser. The Excimer laser removes a predetermined amount of tissue from the inner cornea to correct the individual's refractive error. The cornea is made flatter to treat nearsightedness, steeper to treat farsightedness and/or more spherical to correct astigmatism.

A blade, called a microkeratome, is used to cut a flap in the cornea. A hinge is left at one end of this flap. The flap is folded back revealing the stroma, the middlesection of the cornea. Pulses from a computer-controlled laser vaporize a portion of the stroma. The corneal flap is placed back in its original position where it bonds without the need for stitches.

Excimer Laser - A Revolutionary New Tool Doctors have been routinely treating nearsightedness, farsightedness and astigmatism for over 25 years. By the early 1980s, they began looking at lasers to improve the precision and predictability of altering the shape of the cornea. Researchers found that IBM's new Excimer laser, used initially for etching computer chips, had medical applications as well. Now in its second decade of use, the technologically-advanced Excimer laser has added a tremendous amount of precision, control and safety to treating nearsightedness, farsightedness and astigmatism.

Its ability to remove corneal tissue with accuracy up to 0.25 microns (0.00004 of an inch) with each pulse makes the Excimer laser well suited for correcting vision. Often, only 50 microns of tissue (about the thickness of a human hair) are removed to achieve the proper amount of correction. The Excimer laser produces a "cool" light beam that does not damage surrounding tissue. High-energy photons from the laser break the molecular bonds a few layers at a time.
