LASIK is a revolutionary eye treatment that allows you to get rid of spectacles or contact lenses through a safe and short procedure (just 10-15 minutes). This treatment is carried out with a hi-tech, computer-controlled Excimer laser, which is pre-programmed to remodel the shape of the cornea with a great degree of precision to correct refractive errors.

Who Can Undergo LASIK Treatment?

Anyone who wears spectacles or contact lenses can undergo this treatment, but it is usually recommended after 18 years of age when the eyeball stops growing. Even after this age, your refractive error (number) should be stable for over a period of 1 year before this treatment is contemplated.

LASIK is generally not recommended in the following situations:

  • Age below 18 years
  • Unstable or constantly changing number
  • When a patient has only one eye with good vision
  • Pregnancy or nursing
  • Severely dry eyes
  • Very high hypermetropia (plus numbers)
  • Corneal opacities & other corneal pathologies (e.g., keratoconus)

How is the Number Removed in LASIK?

The laser precisely reshapes the cornea based on your specific prescription:

  • For Myopia (nearsightedness): The laser beam flattens the central part of the cornea.
  • For Hypermetropia (farsightedness): The laser beam is directed at the mid-peripheral cornea to make it steeper.
  • For Astigmatism: The laser beam is directed obliquely to smoothen the corneal surface into a more regular shape.

How is LASIK Eye Treatment Done?

The procedure is precise and quick, involving three main steps:

  1. Step 1: A suction ring is placed on the eye to stabilize it. An automated microkeratome or a Femtosecond Laser (bladeless) is used to create a thin corneal flap, which is lifted and folded back.
  2. Step 2: The pre-programmed Excimer Laser is centered above the eye to deliver precise, cool laser impulses to reshape the cornea.
  3. Step 3: The corneal flap is repositioned. It adheres naturally within minutes. The patient can blink normally, and the flap remains in position.

What are the Newest Techniques in LASIK?

LASIK technology is constantly evolving. At Trivision, we offer the latest advancements for enhanced safety and precision:

  • FemtoLasik: A 100% bladeless procedure where the flap is created using a high-precision femtosecond laser instead of a blade.
  • Flapless Procedures: Schwind ATOS SmartSight (Our USP) and SMILE. These are minimally invasive procedures that correct vision without creating a flap, offering excellent stability.
  • Wavefront Guided / Customised LASIK: Uses 3D mapping to create a "fingerprint" of your eye for a truly personalized treatment.
  • Presbyopic LASIK: A recent innovation that creates a multifocal cornea to help patients above 48 get rid of both distance and reading glasses.

Your LASIK Questions Answered by Bandra Experts

The treatment is not painful. The cornea is completely numbed with eye drops (no injections). The entire process for both eyes takes about 10-15 minutes, with the laser treatment itself lasting only a few seconds per eye. You may feel slight discomfort or pressure, but no pain. Patients go home within half an hour.

Yes, a pre-LASIK check-up is mandatory to ensure your eyes are safe for the procedure. This includes tests like corneal topography (corneal mapping), pachymetry (corneal thickness measurement), retina evaluation, and dry eye tests.

Results are excellent and highly predictable, especially for mild to moderate refractive errors (Myopia from –1 to –12D, Astigmatism from 1 to 6D). In very high-power cases, some patients may still need glasses, but of a much lesser power. For most patients who undergo LASIK after their number has been stable, there is generally no chance of the numbers coming back.

Yes, LASIK is almost always done on both eyes on the same day, one after another. This is advisable as it allows for faster visual recovery and avoids any post-operative double vision or imbalance.

Recovery is very fast. Most patients can get back to work in 1-2 days. Key instructions include:

  • Use post-operative eye drops as prescribed.
  • Avoid rubbing the eyes or splashing water directly for a few weeks.
  • Head bath is allowed after 2 days (avoiding water in eyes).
  • Avoid swimming, steam, and sauna for 3 months.
  • Avoid dusty environments for one week.
