FAQs on Lasik

1. What is Lasik surgery? Can everybody get a Lasik done?
 Lasik (short for Laser-Assisted in Situ Keratomileusis) is a vision correction surgery in which laser is used. Vision is corrected by changing the shape of the cornea so that the rays of light can bend better and fall on the retina more precisely.  Lasik may not be suitable for everyone. One needs to undergo thorough evaluation to ascertain whether one is a right candidate for surgery. If the pressure in your eye is too high, if your cornea is too thin or irregular or bulging etc., you may not be eligible for Lasik Surgery.

 2. What is the latest in Laser vision correction?
 The conventional Lasik involves two steps. First, a flap is created on the cornea using a blade (called the micro keratome). This is followed by the application of a laser beam to reshape the cornea. The next advancement in Lasik is the Femto Second which is an advanced bladeless surgery. The latest technology, called ReLEx (short for Refractive Lenticule Extraction) now makes it possible to undergo a bladeless and flapless surgery with far greater precision and accuracy. The latest in laser vision correction called Lasik Xtra now opens up the world of Lasik to those with borderline thin corneas too! All these are now available in Navi Mumbai.

 3. For how many years do the effects last? Is the procedure very painful?
 LASIK is a permanent procedure. Thus you can get rid of your current spectacle numbers. The eye may be a little itchy after the procedure, but the procedure itself is not painful thanks to the anaesthetic eye drops. A minor pain medicine may be required after surgery.

4. Is it safe? Are there any risks?
 The US FDA has approved Lasik as a safe procedure. Thousands of people all over the world have safely undergone Lasik over the years. With newer technologies, the precision and safety have reached very high standards. Like any surgical procedure, LASIK too has certain risks of complications which are fortunately very rare. They may be:
 Infection of the cornea  - is dealt with antibiotics.
 Under Correction - If too little tissue is removed, requiring enhancement later.
 Over Correction - If too much tissue is removed, this can be corrected with enhancement.
 Displacement of flap can be prevented with the use of protective eye shields and is not seen with ReLEx procedure.
 Dry eyes - There is a temporary decrease in tear production which may require the use of artificial tears.

5. What are the restrictions that I would be required to follow after my surgery?
You will be required to wear a protective shield for the first two nights after the procedure. Swimming and using a hot tub should be avoided the first two weeks after Surgery. Using cosmetics around the eyes should be avoided for a few weeks. Bathing and exercising are allowed right from the next day.

6. Will this surgery require me to be away from work for many days?
You can resume work the next day if your vision permits. However, doctors usually recommend that you rest your eyes for at least 2 - 3 days.

7. I am scared of needles and blades. Will Lasik involve too much cutting?
If needles and scalpels scare the devil out of you, we have good news for you! The latest Lasik machines at the Centre for Lasik Surgery eliminate the need for large cuts or creation of flaps on your cornea as was the case with all earlier Lasik techniques.
