LASIK is the most commonly performed refractive procedure today. From 1990 to the present, over 10 million LASIK procedures have been performed worldwide establishing refractive surgery as the second most common ophthalmic surgical procedure, behind cataract (more than 10 million surgeries per year worldwide). In 2003, in USA alone, more than 1.2 million LASIK surgeries were performed.
There are no needles, no stitches, and no pain. Prior to the procedure, drops are placed in the eye to anesthetize it (like the ones used to check your eye pressure for a glaucoma test) and an instrument called speculum is placed in the eye to prevent you from blinking.
LASIK is a 3-step procedure:
A specially trained ophthalmologist uses an automated instrument called a microkeratome to create a thin, uniform flap in the cornea.
The surgeon then folds the flap back to apply a computer-guided Excimer laser treatment to gently remove a thin layer of tissue from the exposed corneal surface to achieve a desired correction. This is a cold laser and it ablates or vaporizes tissue away to microscopically reshape the corneal surface.
After the computerized laser therapy is applied, the surgeon replaces the flap, where it naturally re-adheres in its original position.
This treatment microscopically reshapes the cornea, resulting in greatly improved visual acuity without glasses or contacts. In just 24 hours following surgery, a vast majority of people see 20/40 or better. This continues to improve as the days pass, with the cornea healing with the assistance of medicated drops. Many people are able to return to work in one to two days. Discomfort is generally limited to some mild burning sensations or foreign body sensations in the eyes for a few hours.
Today, LASIK has become the procedure of choice because the healing occurs in the interior of the cornea, and no re-growth of surface cells is required. The corneal flap protects the treated area and there is usually little or no post-op discomfort. Visual rehabilitation is much quicker and regulation of the healing process with long term post-op drops is unnecessary since the center of the cornea tends to have much less of a healing reaction than the surface.
Advantages of LASIK Eye Surgery
Wavefront LASIK Eye Surgery has been proved to be the sage and effective eye surgery. The patients can be very pleased with the LASIK results by careful patient screening and selection, reasonable expectations and the care of the experienced San Francisco LASIK Surgeon. There are more advantages of LASIK eye surgery. LASIK can correct myopia, hyperopia and astigmatism. The surgery is really fast and painless. It will take only five to ten minutes. The result will be very precise and accurate since the laser will be guided by the computer. Generally a single treatment will get the desired outcome. At the same time enhancements are possible if required even after many years of the initial surgery.
Disadvantages of LASIK Eye Surgery
Though LASIK eye surgery has many advantages. There are some disadvantages that has to be know. Each patients will heal differently and the results will vary from patient to patient. In rare cases LASIK will make the vision worse like night vision with glare and halos. In very rare cases the surgery will make your vision worse and not correctable with the use of regular glasses and contact lenses.
