What is Lasik Surgery?


“LASIK” is a type of eye surgery. LASIK means laser-in-situ keratomileusis. It is a very famous surgery that corrects vision in people. LASIK corrects refractive errors. People who are farsighted, nearsighted, or have astigmatism can connect to LASIK. 


  • Myopia (Nearsightedness): You can see the things close to them. But distant stuff you can’t see correctly.
  • Hyperopia (Farsightedness): Here, you can see things far away. The more intimate items are blurry.
  • Astigmatism: This makes everything blurry to your eyes.

LASIK has a very high success rate. You can reduce your dependency on using glasses. For some LASIK patients, their vision problems are not due to LASIK. The eyes are changing with age and time. As cataracts develop, patients slowly lose their vision and clarity. 

The eyes change with age, and time is the development of Presbyopia. Presbyopia occurs as the eyes lose their natural ability to concentrate. People who are 40 and above years old use reading glasses to see more appropriately. Presbyopia will not help patients with cataracts if they take LASIK twice. LASIK cannot help if vision problems are due to Presbyopia.

What is the process of LASIK?

LASIK eye surgery is a three-step process:

  1. Using a laser, the eye surgeon creates a hinged flap in the cornea and folds the flap gently back to show the cornea.
  2. Then, the eye doctor uses a different laser called an excimer laser to reshape the cornea’s surface. It will correct nearsightedness, farsightedness, and astigmatism.
  3. After the correction is done, the eye doctor repositions the hinge flap and heals in place without any stitches.

During the process, it will ask to concentrate on a red light, which is not the laser but the light the eye surgeon uses to help to keep your eyes steady. They use state-of-the-art laser technology, a tracking device that follows your eyes to ensure an effective, efficient, and safe LASIK surgery.

What will happen if you blink during LASIK surgery?

You may think that if anyone moves, sneezes, blinks, or even coughs, something scary will happen during LASIK eye surgery (https://www.visualaidscentre.com/lasik-eye-surgery-in-delhi/). But, it is not at all problematic. You may have a vision in your mind. You will be lying down in a better position to support your head. Then, your laser surgeon will use a blinking retainer to hold the eyelid. 

Eye surgery equipment can track the eye’s movements 4,000+ times per second. Your laser eye surgeon who uses the surgical equipment is accurate and precise. Nowadays, LASIK is one of the most successful types of surgery. It has minimal risks and very few side effects. 

Do Injections or Needles Use To Numb the Eye During LASIK Laser Eye Surgery? 

 LASIK surgery does not use injections and needles. Instead, topical anesthetic drops are the primary anesthesia used to numb the eye during laser surgery. Patients are awake and comfortable during this surgery. The only anesthetic used is an eye drop, which effectively numbs the eyes.

Also, the patients are not put to sleep with general anesthesia during their LASIK laser eye surgery. Patients are comfortable during their surgery and are awake. They do not see anything scary coming toward them and do not feel any harm or pain. LASIK eye surgery is of concise duration. It hardly takes two minutes or so per eye. Suppose patients feel nervous just before having surgery. They have a mild oral sedative (Valium) that can give right before the surgery. Most patients do not choose this and find the surgery surprisingly and shockingly easy and quick to go through.

One of the main reasons that patients should not sleep during LASIK is that general anesthesia is higher than the risk of LASIK. And it just is not necessary to put patients to sleep during their LASIK laser eye surgery. The exception to this is that, in reality, in some cases, very young pediatric patients place under general anesthesia and put to sleep during their surgery. But LASIK in this very young pediatric population remains controversial and should only be performed cautiously.
