Tampa LASIK – Laser Vision Correction Surgery

What is LASIK?

Laser In-Situ Keratomileusis (LASIK) and Photo-Refractive Keratectomy (PRK) are two surgical techniques, which utilize lasers to reshape or change the curvature of the cornea.

The cornea and lens combine to focus visual images on the back of the eye. When the overall shape of the eye is incorrect, or when the curvature of the cornea is incorrect, the visual images are not in focus. The cornea accounts for approximately 2/3rds of the focusing power of the eye. By surgically changing the corneal curvature, most or all of the blur can be eliminated.

LASIK

LASIK had its origins about thirty years ago and was originally developed to treat patients who had very poor vision due to corneal disease. It has now evolved into a successful technique for correcting refractive errors. The current procedure, done on an outpatient basis, involves the use of laser surgery to correct nearsightedness, farsightedness, and astigmatism. LASIK can correct a much higher degree of nearsightedness and farsightedness with or without astigmatism than any other refractive procedure, with excellent results (99% of patients achieve 20/40 vision or better).

In performing LASIK, eye drop anesthetic is used to numb the eye. David H. Leach, M.D., then uses the IntraLase Laser to create a flap. The flap is then laid back to expose the inner portion of the corneal tissue. The eye is then positioned under the Allegretto Wave Laser, which has been computer programmed to remove microscopic amounts of the internal corneal tissue. Removal of the tissue changes the curvature of the cornea. If the patient is nearsighted, tissue closer to the central part of the cornea is removed to decrease the curvature or flatten the cornea. If a patient is farsighted, tissue in the peripheral part of the cornea is removed to increase the curvature of the cornea.

To correct for astigmatism, selected tissue at certain angles is removed to ensure that the cornea curves equally in all directions. After the laser has been used, the flap is returned to its original position. The corneal tissue has extraordinary natural bonding qualities that allow effective healing without the use of stitches.

Since only topical numbing drops are used, patients remain awake during the procedure. The entire procedure takes only a few minutes. Improved vision is often possible on the day following the surgery. Eye drops and night protection are necessary for designated periods of time.

Advantages of LASIK include:

  • Faster healing time
  • Rapid visual recovery
  • Less post-op discomfort
  • Both eyes can be done at the same time
  • Treatment of a wider range of nearsightedness,farsightedness, and astigmatism.
