LASIK and CORNEA



LASIK


LASIK (laser-assisted in situ keratomileusis) is an outpatient refractive surgery procedure used to treat near sightedness, farsightedness and astigmatism. A laser is used to reshape the cornea — the clear, round dome at the front of the eye — to improve the way the eye focuses light rays onto the retina at the back of the eye..

Procedure:


With LASIK, an ophthalmologist (Eye M.D.) creates a thin flap in the cornea using either a blade or a laser. The surgeon folds back the flap and precisely removes a very specific amount of corneal tissue under the flap using an excimer laser. The flap is then laid back into its original position where it heals in place.

For people who are near-sighted, LASIK is used to flatten a cornea that is too steep. Farsighted people will have LASIK to achieve a steeper cornea. LASIK can also correct astigmatism by shaping an irregular cornea into a more normal shape.

For clear vision, the eye's cornea and lens must bend (refract) light rays properly. This allows images to be focused on the retina. Otherwise, the images will be blurry.

This blurriness is referred to as a "refractive error." It is caused by a difference between the shape of the cornea (curvature) and the length of the eye.

LASIK uses an excimer laser (an ultraviolet laser) to remove a small amount of corneal tissue. This gives the cornea a new shape so that light rays are focused clearly on the retina. LASIK causes the cornea to be thinner.LASIK is an outpatient surgical procedure. It will take 10 to 15 minutes to perform for each eye.

The only anesthetic used is eye drops that numb the surface of the eye. The procedure is done when you are awake, but you will get medicine to help you relax. LASIK may be done on one or both eyes during the same session.The amount of tissue the laser will remove is calculated ahead of time. Once the reshaping is done, the surgeon replaces and secures the flap. No stitches are needed. The cornea will naturally hold the flap in place.

Dr. Smita Gupta has extensive experience in LASIK Surgery and is well versed with the techniques and has extensive experience to treat vision related problems using LASIK.

The advantages are:


  • No injection
  • No prolonged medication
  • No surgery
  • Totally an out-patient procedure
  • Can resume job or college within 2 days
  • Treatment time per eye is only 1-2 minutes
  • Better quality of vision than glasses and contact lenses
  • Normal activities can be resumed the next day
  • Permanent, once in life time treatment

The latest trend in refractive surgery has been a focus on more customized treatments for patients. Customised laser surgery involves a personal as well as unique laser vision correction that is designed for each eye individually
