What is LASIK? The Fastest Way to See Clearly
Laser Vision Correction procedures have improved eyesight for millions of people worldwide. Over one million Americans experience the thrill of Laser Vision Correction every year. A constant topic of conversation in social circles and in the workplace, nearly everybody knows or is related to someone who has undergone the lifestyle changing procedure. Still, most people truly don't know what LASIK is.
LASIK stands for Laser Assisted In-Situ Keratomileusis. LASIK is a procedure, which utilizes a cool ultraviolet wavelength energy beam emitted from an Excimer laser to reshape the curvature of the cornea. The newly shaped cornea has improved ability to focus light clearly, without glasses or contact lenses. Using the latest techniques Dr. Barrett can improve the vision of virtually any patient with nearsightedness, farsightedness, or astigmatism.
The seven minute LASIK procedure consists of three basic steps which, when performed by a Dr. Barrett, can dramatically improve vision within hours. First, a thin flap of corneal tissue is created with an instrument called a microkeratome, which glides across the corneal surface. Next, the Excimer laser pulses gently reshape the corneal surface with amazing accuracy and precision in less than a minute. Finally, after the laser treatment has been completed, the corneal flap is replaced in its original position and allowed to seal into place.
The entire procedure is fast, effective and pain-free. By adjusting the laser beam pattern, it is possible to treat nearsightedness, farsightedness, and astigmatism. Both eyes can be treated at the same session.
Most patients who undergo LASIK will notice significant improvement of their vision within a few hours. Many patients feel comfortable driving to the office and going to work the next day.
LASIK Step 1:
A hinged flap is created with a microkeratome. The flap is gently lifted up, exposing the underlying corneal surface.
LASIK Step 2:
Pulses of Excimer laser energy gently reshape the surface of the cornea.
LASIK Step 3:
The corneal flap is replaced. The flap naturally seals to the cornea without stitches.
