LASIK Largo, Clearwater, St. Petersburg, and Tampa
LASIK (Laser in Situ Keratomileusis) is a minor all laser outpatient procedure that corrects nearsightedness, farsightedness and astigmatism and is intended to reduce or eliminate dependence on glasses and contact lenses. During the procedure, our physicians create a flap from the outermost layer of the cornea using the latest femtosecond laser or "bladeless" technology. The flap is folded back revealing the middle section of the cornea. The cool beam of the excimer laser removes tissue and gently reshapes the cornea. The top layer of cornea is then replaced to serve as a protective cover. For nearsighted or myopic patients, the cornea is too steep. The LASIK procedure removes cells from the central part of the cornea flattening it for clearer vision. For farsighted or hyperopic patients, the cornea is too flat. The LASIK procedure removes cells from the peripheral of the cornea. This steepens the cornea and creates clearer vision. For astigmatism, a combination of both is used to precisely reshape the cornea for clearer vision.
The flap is then replaced and, in most patients, has already healed significantly within twenty-four hours. The natural suction of the eye holds the flap in place. No sutures are necessary. These permanent adjustments allow the cornea to focus light onto the retina of the eye, resulting in normal focus without glasses!
The Evolution of LASIK
There were several laser vision correction procedures being performed before LASIK (Laser in Situ Keratomileusis). Through the developmental stages of laser vision correction surgeons noticed certain side effects and limitations with the original procedures. As time went on, each procedure developed a more predictable result and faster recovery. LASIK embodies the positives of ALK, RK and PRK without the pain and long recovery periods. The following will briefly highlight pros and cons of these procedures.
RK, or Radial Keratotomy, was popular in the 1970's. The surgeon would make radial incisions on the surface of the cornea, resulting in a flattening effect in the cornea and visual axis. This procedure culminated in a slightly painful recovery, due to the abrasion created by the incisions. Furthermore, in the long-term the shape of the cornea was often rendered irregular and unstable.
PRK, or Photorefractive Keratectomy was the next improvement to vision correction. Rather than making radial incisions on the cornea, an excimer laser was used to sculpt and reshape the surface of the cornea without making a flap. With PRK, patients experienced gradual visual improvement over a few days or even months and may have mild discomfort for approximately 48 to 72 hours while healing.
LASIK, as with PRK, uses an excimer laser to reshape the surface of the cornea. In this procedure, a mechanical device, called a microkeratome, uses a blade to make a flap in the outer layer of the cornea. The flap is folded back, exposing the corneal tissue to allow the excimer laser to gently reshape the surface. The flap is then carefully replaced into its original position. The natural suction of the eye holds the flap in place, much like the eye would do with a contact lens, without sutures. With LASIK, patients experience virtually no pain, have no scar tissue and have highly predictable results.
ALL-LASER LASIK utilizes the most advanced vision correction technology available. The procedure is similar to traditional LASIK but uses the latest laser technology instead of a blade to make a more precise LASIK flap. Bladeless technology is guided by the precision and accuracy of the laser to define the flap diameter, its thickness and hinge position for the most comfortable patient experience. The benefit of all-laser LASIK reduces surgical risks, minimizes complications and improves results. Furthermore, this cutting edge technology affords laser vision correction to those patients who may not have otherwise been a candidate using traditional LASIK technology.
