LASIK & Refractive Surgery

Live Life Glass-free

Have been behind the spectacles whole your life and want to get rid of them now? You have landed on the right page.


Laser-Assisted In Situ Keratomileusis, more popularly known by the name of LASIK, is a procedure that corrects vision problems and altogether eliminates the necessity of spectacles or corrective lenses.
This refractive surgery reshapes the clear round dome at the front of the eye (cornea) and bends the rays of light to focus on the retina instead of someplace else. The end result is a sharper and clearer vision.

LASIK surgery corrects the following refractive errors:

  • Nearsightedness (Myopia): A condition where you are able to see the nearby objects clearly but not far away things. Both these cases consequent the light rays to focus on retina’s front rather than on it, blurring faraway vision.
  • Farsightedness (Hyperopia): A condition where you are able to see the distant objects clearly, but not the nearby things.
  • Astigmatism: Persistent blurred state of near and far away vision due to corneal uneven curves or flatness.
  • Presbyopia: Also called the ‘Aging Eye’ condition, it refers to long-sightedness caused by the loss of elasticity of eye lens occurring generally in the middle & old age.

Centre for Sight has been providing the most advanced LASIK treatment options for the correction of all these refractive errors for many years now.

Understanding the evolution of LASIK

LASIK has been making waves in the medical world for almost 25 years. Earliest days witnessed the oncoming of Refractive Keratectomy (RK) in which manual cuts were performed on the eye to alter the shape of the cornea.

Blade-free LASIK made its advent a decade ago concentrating on removing the corneal tissue in order to give it a new shape. A superior feat than its predecessor, this procedure used FEMTO laser to create a corneal flap and guaranteed precise results. However, there was a minor setback. Despite being a bladeless procedure, doctors still had to create a corneal flap. Small Incision Lenticule Extraction (SMILE) eliminated that too.

Types of LASIK Eye Surgery

Different type of LASIK treatment is chosen by different patients according to their suitability and eligibility for the procedure. All these solutions stand to be safe and reliable.

PRK/Surface Ablation: The Excimer laser procedure is used and a bandage contact lens is placed. The healing process involves slight pain in the early phase and causes a slight delay in visual recovery. However, because of its numerous advantages, it is still a preferred technique for the patients who are deemed unfit for LASIK flap creation.

Clasik/Blade LASIK: The LASIK procedure uses an extremely fine blade named ‘MicroKeratome’ to cut the corneal flap and then employs Excimer laser for corneal shape correction.

Bladefree/Bladeless/ilasik: No manual blade needed here. A Femto laser creates a clean and precise flap minimising every possible complication of a blade.

Small Incision Lenticule Extraction (SMILE): Currently the best procedure for specs-removal, this 100% blade-free laser vision correction method needs no flap at all. Patients experience little discomfort for a couple of hours, but resume routine activities almost immediately after the procedure. Computer controlled for maximum precision, SMILE takes only 20-30 seconds per eye.

Advantages of opting for SMILE procedure over the conventional LASIK treatment include:

  • No Corneal Flap Creation – Meaning no risk of corneal flap displacement or any subsequent complications occurring.
  • Less Dry Eyes: Small incision makes sure that there is almost no cutting of corneal nerves, resulting in the less dry eyes & improved corneal sensitivity.
  • Better Corneal Biomechanics: There is minimal to almost no loss of corneal biomechanical strength.
  • Greater Precision & Stability: SMILE uses a Femtosecond Laser and not an Excimer Laser, which means that the total energy introduced by the laser into the eye is 10-times lower, less inflammation, and has greater stability.
  • Fully Automated & Quick: This process takes only 20-30 seconds per eye and has delivered outstanding visual results with more patients achieving 20/20 vision.
  • Enhanced Ability To See Clearly In Low Light: Patients are able to see much better in dark, even at dusk or at night.

Q1. Is LASIK surgery painful?

The LASIK procedure is almost painless and is performed with topical drop anaesthesia. Patients can walk in and out of the operation theatre in less than 15 minutes.

Q2. Can you blink during LASIK?

A speculum is placed on the eye that prevents a person from blinking during the procedure.

Q3. Can I watch TV/use the mobile phone after LASIK surgery?

Though watching TV will not harm the eyes, you will have difficulty for a few days as your eyes heal.

Q4. How long do I wear sunglasses after LASIK?

For about 3 days indoors and 3 weeks outdoors.

Q5. How long after LASIK will the blurry vision go away?

Most of the blurriness goes away by about the next day, though the clarity gradually increases over a couple of weeks.

Q6. How many days of rest is required after LASIK surgery?

No bed rest is required after the LASIK surgery.

Q7. How long after LASIK will my vision stabilize?

Usually, the vision continues to stabilize for until about a month.

Q8. When can I rub eyes after LASIK?

You should avoid rubbing the eye after LASIK surgery for a couple of weeks.

Q9. Can I shower after LASIK surgery?

You should take a below-the-neck bath for a few days after the surgery.

Q10. Can you drive after LASIK surgery?

Should be avoided until the eyes heal.

Q11. Can you see immediately after LASIK?

Yes, but your vision might be slightly blurred.

Q12. How long should you sleep after LASIK?

You can follow your normal sleep/wake pattern after LASIK Surgery.

Q13. Can laser eye surgery go wrong?

If the laser removes too little/too much tissue from your eye, you won't get the clear vision results you were hoping for. This can be corrected by a repeat procedure after the eye heals completely.

Q14. Can LASIK make you go blind?

No reported cases of blindness caused by LASIK exist. Nevertheless, when the correct aftercare protocol is not observed, the resulting complications (especially infections) can cause blindness. This is extremely rare but has happened. LASIK surgery itself does not cause blindness, and most cases of LASIK complications are avoidable by following aftercare procedures set forth by the surgeon.
