Laser-assisted in situ keratomileuses (LASIK) eye surgery is quite common and is basically a laser refractive surgery to rectify vision issues. It is done as an alternative to contacting lenses and glasses.

This is performed using a cutting laser to transform the shape of the cornea to amend your vision. Precisely the cornea refracts light on the retina in case of normal vision eye. On the other hand, the light refracts in an incorrect way in the case of farsightedness, nearsightedness, or astigmatism. Glasses and contact lenses can be an option while changing the shape of the cornea could also give refraction.

Why Lasik Eye Surgery?

Lasik surgery is performed to rectify the below-mentioned vision problems:

Nearsightedness (myopia):

Myopia is when one can see closer objects clearly but farther objects blurry.

Farsightedness (Hyperopia):

Hyperopia is when you see further objects clearly but blurry when seeing nearer objects.


When the shape of the cornea is uneven, then everything seems to be blurry. This condition is called astigmatism.

Note: You must only go for this operation if you're wearing contact lenses or glasses. Always consult a doctor on whether this procedure will be the correct option for you or not.

Don't opt for this operation for these reasons:

• Below 18 years

• If you're pregnant

• On medications

• Have a recent check-up for vision

• Thin or uneven cornea

• Dry eyes or glaucoma

• health conditions like diabetes, arthritis, and lupus.

Possible Risks of Lasik Surgery:

Dry eyes:

Lasik eye surgery causes unusual dry eyes that might cause damage to your vision. It could temporarily decrease the production of tears.

Under corrections:

In case the procedure releases little tissue then you might not have a clear vision as expected and one more Lasik procedure is needed in order to release some more tissues.


It would get tougher when the laser would release more tissues.


Regression is when your vision slowly changes back toward your original prescription. This is a less common complication.

Vision loss or changes:

The complication may lead to vision loss.

Lasik Surgery Side-effects:

  1. Glare
  2. Seeing halos around images
  3. Trouble night driving
  4. Vision fluctuate
  5. Dry eyes
  6. Scratchy eyes
  7. Light sensitivity
  8. Bruises on your eye
