LASIK or “laser-assisted in situ keratomileusis” is a type of eye surgery to correct vision problems. It is one of the best-known and most commonly performed refractive eye surgeries. LASIK can be a suitable option for you if you have vision problems but do not want or cannot opt for corrective eyeglasses or contact lenses. Let’s find out about this surgery in detail in this article.
LASIK, which stands for "laser-assisted in situ keratomileusis, is a refractive eye surgery that employs lasers to correct vision problems.
In eyes with normal vision, the cornea (the clear, dome-shaped front part of the eye) bends or refracts light correctly onto the retina (the light-sensitive layer at the back of the eye) and creates clear vision. However, when someone suffers from a refractive error, their eye is unable to bend the light correctly, which results in blurred vision.
LASIK is refractive surgery. It corrects the refractive error by reshaping the cornea so that it is able to refract light as it should, and the eye forms a clear image. LASIK surgery employs a special type of cutting laser to change the shape of the cornea and improve vision.
LASIK surgery may be recommended for those who have the following vision problems:
Nearsightedness: Also called myopia, this is a refractive error due to which you can see objects that are close by clearly (nearsighted), but objects farther away appear blurred.
Farsightedness: Also called hyperopia, this is a refractive error that makes near vision blurry whereas objects far away usually appear clear (farsighted).
Astigmatism: This is also a refractive error in which an irregularly shaped cornea causes blurred vision of objects at any distance, near or far.
These are the steps involved in LASIK surgery.

No, pregnant women are advised to postpone LASIK surgery until after delivery and the completion of breastfeeding. The hormonal changes and fluid retention associated with pregnancy can give rise to vision changes that can compromise the results of the surgery. LASIK also involves the use of a laser and the administration of local or topical anesthesia, which may pose risks to the mother and the developing child.
LASIK changes your vision permanently by changing the shape of your cornea irreversibly. However, your vision may change over time if the initial condition that affected your vision (nearsightedness, farsightedness, or astigmatism) continues to progress. You may also face presbyopia or age-related vision change following LASIK.
Got to know about them from my friend. They got an appointment for only 299. Once the doctor confirmed that I needed the surgery they got me a fixed cost which included ALL the costs. No extra amounts were charged. Thank you Medfin
After my consultation with the doctor, MEDFIN representative got me a fixed package cost that included my mothers initial tests, surgery cost. They also gave me stockings free for Rs. 3000 post the surgery. They kept up their promise they made
