What is LASIK Surgery?

The full form of LASIK is Laser in Situ Keratomileusis. This surgery corrects several vision problems such as myopia (nearsightedness), hypermetropia (farsightedness) or astigmatism. In this procedure, a specialized laser is used to reshape the cornea so that the light entering the eye gets focussed on the retina. This is a common procedure that several people opt for when these eye conditions interfere with daily life. Some people also choose to undergo LASIK surgery so that they don’t have to wear glasses or contact lenses anymore. 8 out of 10 people who undergo LASIK surgery do not need to wear glasses or contact lenses. LASIK surgery are of primarily three types- conventional laser treatments, wavefront-optimized treatments, and wavefront-guided treatments.


Eye injury

Short eye ball

Inflammation of the cornea due to any eye disease

Abnormal curve of the cornea

Having a weak immune system


Eye test for LASIK surgery in disease


Your ophthalmologist will assess your eye and check the vision clarity. Your doctor might ask you to go through an eye chart test to check your vision from a distance. The doctor might also check your eye pressure. This is known as the tonometry test.

To check your pupils, the doctor might put drops in your eyes which will make the pupils bigger. This is done to check the optic nerve and to confirm if there is any damage to the retina of the eye.

The ophthalmologist might ask you to do a few more tests to check your eye's sensitivity to glare and perception of colors.


First, the eye is sedated with anesthetic eye drops. Once the anesthesia takes its effect, the doctor uses an instrument, lid speculum, that keeps the eye open to position it under the laser beam. With the help of a suction ring and an ink marker, any kind of eye or cornea movement is restricted. Followed by this, the surgery passes the laser beam through the eye that reshapes the cornea. Meanwhile, he/she checks the progress through a microscope. In order to rectify myopia, the cornea is flattened and to correct hypermetropia, the cornea is made steep. Once the reshaping is complete, the cornea is placed back.

The whole procedure takes 10-20 minutes to complete and performed on an outpatient basis. After a quick follow-up by the doctor, the patient can go home on the same day.

  • Make arrangements before the surgery by asking someone to drive you back after the surgery
  • On the day of the surgery, do not wear any makeup, perfumes or lotions
  • When you come to the hospital, wear comfortable clothes, preferably opening in the front

Risks of LASIK Surgery

LASIK surgery is a quick and safe procedure. But as it involves making changes in the anatomy of the eye, there can be some minor side effects. Some of the common risks that can occur after LASIK surgery are-

  • Infection in the eyes
  • Oversized pupils
  • Dryness of the eyes
  • Glare and halos
  • Double vision
  • Astigmatism
  • Problem with the flap that leads to infections and tears
  • Regression which is the vision changing back to the patient’s original prescription
  • Loss of vision
  • Change in vision
  • Undercorrection in which the laser doesn’t removes remove sufficient tissue
  • Overcorrection in which the laser removes excess tissue from the cornea

Recovery after LASIK Surgery

It takes around 6 to 12 hours for the initial recovery after LASIK surgery to complete. Generally, the patient can have a clearer vision within 24 hours of the surgery. However, some people may take two to five days. LASIK surgery incurs some common side effects but these can be easily cured if proper post-operative instructions are put in place. Below mentioned are some common tips prescribed by Pristyn Care doctors-

  • Do not drive yourself back home after the procedure.
  • Protect the eye with an eye patch even when you are sleeping to prevent damage.
  • For the first four days of the recovery, do not put any pressure on any of the eyes.
  • Do not go for swimming at any cost during the entire recovery period.
  • Avoid taking part in any contact sports as this increases the chances of infection.
  • Once you reach home, take proper rest for the entire day.
  • Neither read nor watch television as it can put a strain on the eyes.
  • Use the prescribed eye drops containing antibiotics and steroids as prescribed by the doctor.
  • Visit the doctor to check the progress after the surgery without fail.
