LASIK Treatment

Sundar Eye Hospital offers LASIK vision correction in a world class environment. We are your key to a world without spectacles.



What is Laser vision correction?

Photorefractive keratectomy, Laser in situ keratomileusis (LASIK) and refractive lenticule Extraction are laser based procedures that correct the refractive power of the eye at the level of the cornea. In PRK the most superficial layer i.e., the epithelium of the cornea is removed, and the refractive power is corrected on the surface of the cornea. In LASIK a flap is lifted either using a microkeratome or Femto laser and the surface of the cornea is remodeled using laser. In Refractive lenticule extraction there is no flap, only a lenticule of corneal tissue is removed.

Is it a good option for me?


Lasik laser is a good option


  • if you are above 18 years of age

  • If your power has been stable for the last 2 years

  • If your eye is healthy and you are not suffering from diseases like diabetes or severe dry eye.


Your ophthalmologist will do a detailed examination and is the best judge if Laser refractive surgery is a safe option for you.


How will we evaluate whether you’re a good candidate for Laser refractive correction?


To see if safe laser vision correction can be done for your eye, we will first review your previous records. If you are a contact lens user (soft contact lens) please defer using contact lenses for a minimum of 2 weeks prior to the day of evaluation. Toric / RGP users to stop using contact lens for a minimum of 3 weeks and hard lens users for a minimum of a month The refractive error should be stable. A detailed eye exam is done. The retina is checked for microscopic holes and degenerations. If seen, these weak areas are fixed with a green laser. Laser Refractive surgery can then be done 4 weeks later. Tear secretion is measured next to see if an adequate tear film is present. An Orbscan is then done to evaluate the strength of the cornea. The wavefront is captured with an aberometer to see if Zyoptics technology will resultin clearer vision. After these tests are reviewed we will advise you about the safest and best options available for your eye.



What is the procedure?

The process starts off with numbing of your eyes with eye drops. Then, the surgeon will use a lid speculum to keep your eyes from blinking. A suction ring will also be placed to prevent eye movements. Expect your vision to become dim or black at this point.

In Lasik, using a microkeratome or laser, a flap of corneal tissues is created lifted and folded back. The surgeon will then ask you to stare at a blinking light source so that your eyes do not move.

The laser energy will then be applied to correct the refractive power. After the laser the flap is folded back into position and the edges will heal. The process will be painless.

In PRK after the epithelium is debrided, Excimer laser will be applied to alter the surface of the cornea.

In refractive Lenticule extraction FLEX or SMILE a lenticule of corneal tissue of a particular thickness will be removed to attain the desired correction.



What happens after the LASIK procedure?


  • Please have a normal diet from the first day

  • You may experience mild discomfort, tears eyes, starburst like sensation for a few days. They will get better.

  • The face can be wiped with a damp cloth, and you can have a soap and water bath below the neck.

  • Please wear dark glasses during the day. The cup to be taped at might over both the eyes for 1 week

  • Apply drops as instructed and please come for your post procedure visits as requested.
