How is LASIK surgery (LS) performed?

LASIK is a popular corrective surgery using laser to make the cornea more concave. It is a way to correct the refractive error and a small flap like a banana peel is first created and placed on the surface of the cornea, peripherally or centrally using a blade. It is quite a safe and simple surgery that could be performed within 15 to 20 minutes for both the eyes. It is the most appropriate for people having a moderate degree of nearsightedness (myopia) – you can see the nearby objects clearly but distant objects are blurry and farsightedness (hyperopia) – you can see distant objects clearly but nearby objects are blurry or astigmatism that causes overall blurry vision. A good surgical outcome will depend on careful evaluation of the eyes before the surgery.

Latest types of LS

The refractive surgery will change the shape of the dome-shaped transparent tissue or cornea in the front of your eye. The desired result of the LASIK eye surgery is to bend or refract the light rays and focus more precisely on the retina instead of some point beyond or on front. The end result of the successful LASIK eye surgery is clear, sharp vision.

Presently, there are many types of LASIK surgeries available in India, which includes the following:

  1. Conventional LASIK: During this surgery, a disposable blade is used for creating the flap and then excimer laser will be used for the corneal ablation for power correction.
  2. ASA (Advanced Surface Ablation): During this surgery, excimer laser is applied on the cornea in selected cases without creating flap.
  3. Femto LASIK: During this surgery instead of blade, Femtolaser is used to create flap and again an excimer laser is used for power correction.
  4. SMILE: During this type of LS full correction is done with femtolasik without excimer Lasik. Each type has its own indications according to the needs of the patient and your surgeon’s preference.

Precautions taken before the new types of LASIK Surgery

It is important to have a discussion with your ophthalmologist in order to understand the facts before undergoing the LS. You should be minimum 18 years old in order to be eligible for LS You should undergo a complete eye- check up which includes the detailed scan of cornea, especially the anterior part wherein the surgery will be conducted. The patient should stop using the contact lenses, 5 to 7 days before the surgery. If the contact lens used is hard, then you will need to stop using it 15 days prior to the LS.

What to expect during LASIK?

The patient could head home without any hospitalization. Typically, this procedure is performed under the topical (eye drop) anaesthesia. During the surgery, you’ll be asked to lie down on the operating table and focus on a target light above. Usually, patients are quite comfortable throughout the surgical procedure.

Immediately after LASIK surgery

One could soon head home after undergoing a new type of LS. However, the patient will not be allowed to drive back. For three days, he or she should abstain from any activity that will strain their eye. The patient needs to wear the protective goggles. You should not touch the eye frequently. One could completely resume their routine activities, three days post LS.
