Our LASIK information is being revised. Dr. Heyde uses the Visx laser exclusively. This laser is used by more surgeons in the U.S. than any other refractive laser. We ask that you go to www.visx.com to check LASIK, PRK, etc. They have a great website with more information than anyone expects. Again, please visit www.visx.com.
LASIK, or Laser in-Situ Keratomileusis, offers a number of benefits over other forms of laser vision correction because it is performed under a protective layer of corneal tissue. As a result, there is less surface area to heal, less risk of corneal haze, less postoperative discomfort, less postoperative need for medications, and vision returns more rapidly, often within a day or so. LASIK can also treat a higher range of vision errors. Although postoperative results vary, most patients are able to pass a drivers license test without their glasses or contact lenses.
The Procedure
After your eye has been completely numbed using "eye drop" anesthesia, an eyelid holder will be placed between your eyelids to prevent you from blinking. Next, an instrument known as a microkeratome makes a protective flap in the cornea. During this process you may feel a little pressure, but no discomfort. You will be asked to look directly at a target light while the laser reshapes the cornea, usually in less than a minute. Then, the protective flap is folded back in place where it bonds securely without the need for stitches. After LASIK, some patients report a slight discomfort that usually goes away within twelve to twenty-four hours.
How it Works
To treat nearsightedness, the cornea must be made flatter. This is accomplished by removing tissue from the center of the cornea.
To treat farsightedness, the central cornea must be made steeper. This is accomplished by directing the laser beam to remove tissue from around this area.
To treat astigmatism, the central cornea must be made more spherical. By changing the pattern of the beam, tissue is removed in one direction more than the other.
Are you a candidate for LASIK?
In general, the ideal candidate for LASIK is over 18 years of age and has healthy corneas. Candidates must not have had a significant increase in their prescription in the last 12 months. People with certain medical conditions or women who are pregnant may not be good candidates for LASIK.
