LASIK

LASIK

The Excimer Laser

Our doctors always utilize the latest in technology and nowhere is this more important than in LASIK surgery. The VisX Star S4 incorporates wavefront technology to give the most precise outcomes available. The laser will permanently change the shape of the cornea or the outer layer of the eye. The excimer laser generates its power from light in the ultraviolet range. It cannot be visualized by the human eye. Because the laser does not generate any heat, there is no tissue damage as the result of the laser light. As the treatment with the laser proceeds, microscopic layers of tissue, approximately 1/10th the width of a human hair are removed. The laser is programmed to remove precisely the amount of tissue needed to achieve the desired result.

The Lasik Procedure

During LASIK – laser vision correction the surgeon first applies anesthetic eye drops to numb the eye for surgery. The Cornea is then marked with water-soluble ink to guide replacement of the flap. Next, a suction ring is applied that is designed to hold the eye steady and also confirms the pressure of the eye. The surgeon then creates a thin corneal flap using a device called a microkeratome. The surgeon tests for laser alignment and walks the patient through the fixation process. The corneal flap is lifted up, and the laser beam is applied to the exposed interior surface of the cornea to reshape the tissue. The computer-controlled excimer laser removes the tissue under the flap and reshapes the cornea of the affected eye. In less than 60 seconds, high-energy pulses from the excimer laser actually reshape the internal cornea with accuracy up to 0.25 microns, or 1/4000 of a millimeter. The flap is then replaced over the treated area. This corneal flap serves as a natural bandage, which eliminates the discomfort associated with other types of refractive surgery, and expedites the healing process. Your doctor will then watch the eye for five minutes to ensure proper healing. Because of the extraordinary bonding properties of the corneal tissue, stitches are not needed to keep the flap in place postoperatively. The entire procedure usually takes twenty minutes to complete.
