About Lasik Surgery

What is LASIK ?

LASIK is laser vision-correction in the blink of an eye . The ultimate solution to replacing contact lenses and spectacles. LASIK stands for 'Laser In-Situ Keratomileusis' which means ' to shape the cornea within its layers with the use of the Excimer laser'.

Hi-tech solution combining advanced computer technology with laser precision: LASIK is a skilled procedure that combines the state-of-the-art computer technology with advanced laser precision. While the earlier laser procedure viz PRK treated the surface of the cornea, LASIK treats the inner tissue of the cornea and restructures it in a manner which grains down myopia (minus power) and hypermetropia (plus power). Perhaps you suffer from chronic or recurrent neck or back pain or just want to get your body into better shape - we can help!

LASIK procedure -step-by-step:


  • First, the eye surgeon uses an instrument known as a microkeratome to make a thin flap of the outer layer of the cornea.
  • Then he folds back the flap, which remains attached on one side.
  • Next, he uses the cool laser light from the Excimer laser to 'ablate'' i.e. remove the pre-determined amount of tissue to reshape the cornea with great accuracy and corrects the individual's refractive error.
  • The cornea is made flatter to treat near-sightedness, and steeper to treat far-sightedness and/or more spherical to correct astigmatism.
  • AFinally, after the laser is administered, he lays back the corneal flap in its original position, where it bonds itself instantly.
  • Due to the extraordinary natural bonding qualities of the cornea, no stitches or sutures are required. An eye-patch is not required.

  • Contact lens wear should be discontinued for a period of three days in case of soft contact lens and 1 week in case of semi-soft (RGP) contact lenses.
  • Myopia: - 1.00 D to -18.00D.
  • Hypermetropia: +1.00 D to + 6.00 D.
  • Astigmatism: +/- 1.00 D to +/- 6.00 D.
  • Stable refraction i.e. no change in prescription power for six months.

Pre- operative procedure :

  • Age more than 17-18 years.
  • Contact lens wear should be discontinued for a period of three days in case of soft contact lens and 1 week in case of semi-soft (RGP) contact lenses.
  • Myopia: - 1.00 D to -18.00D.
  • Hypermetropia: +1.00 D to + 6.00 D.
  • Astigmatism: +/- 1.00 D to +/- 6.00 D.
  • Stable refraction i.e. no change in prescription power for six months.

Do's and Don'ts of LASIK :

The recovery time and time taken for healing differs from patient to patient. Patients also have different levels of tolerance in performing various activities after the procedure. Some get back to work the next day without any problem.

  • It is advisable to use sunglasses for two weeks when going outdoors to avoid glare.

  • Very low risk of scarring.
  • High degree of predictability.
  • Low enhancement rate.
  • Relatively quick procedure.
