What is LASIK?

LASIK or Laser in Situ Keratomileusis is a world-wide accepted technique of removing dependence on glasses by excimer laser. In this procedure, we first create an extremely thin flap (90µm) on the surface of the eye (cornea) using the Moria SBK microkeratome. Laser is then applied to the bed of the flap to reshape the cornea. All this is done in a precise and controlled fashion.

How does it work?

  The reason you use glasses is that light reaching your eyes does not get focused on your retina. To aid in perfectly focusing images on your retina, you use glasses. After LASIK, the shape of your eye is corrected so that light now focuses perfectly on the retina. Thus you are no longer dependant on glasses! Each person's eyes are unique, so we take scans of the patients before surgery and treat the exact power of the person according to the eye.

What are the advantages of having my LASIK done at R K Netralaya with the Allegretto Wavelight EX500?

The Allegretto Wavelight EX500 is the world's fastest LASIK machine!
It treats your power in a matter of seconds. This ensures that the treatment is highly accurate and not affected by eye movements, corneal dehydration etc. The surgery is also extremely fast and comfortable for you- it is over before you know it! Our patients never complain of any discomfort after the surgery.
Highly efficient treatment of power
Using the Wavelight Allegretto EX500, we need only 12-13 microns of cornea per diopter of power treated. This means that minimal amount of cornea tissue needs to be touched to correct your power, which makes it even safer to have your LASIK done in the long run compared with other machines. This also means that powers which could not be treated with older machines can now be treated using Wavelight Allegretto EX500. LASIK surgery needs to be done only once, so why not go with the best?
Highly accurate results

By looking at the chart above, it is clear that the Wavelight 200 platform gives better results than any other available machine. We use the Wavelight EX 500, which is an even more advanced than the Wavelight 200. This means that there is an even greater chance of your vision being better without glasses! Infact, the Wavelight EX500 is the latest and most sold LASIK machine in highly advanced countries like the USA in recent times. These results are similar to the ones that we are getting at R K Netralaya with our patients and we are yet to find a dis-satisfied patient!
We use the only microkeratome in the world to create a planar flap

We use the state of the art Moria SBK range of microkeratomes which creates a perfect and planar flap of the cornea. This gives our patients enhanced quality of vision. We use the SBK head for our patients, creating a flap of only 90 µm. This allows less corneal tissue to be touched and even safer surgery for you.
Wider range of candidates
Substantially higher level of accuracy allows a larger number of patients previously unsuitable for traditional LASIK surgery (because of thin corneas or high prescriptions) to be treated.
Reduced risk of dry eye
The accuracy of the Moria SBK microkeratome enables reliable creation of THIN flaps thus avoiding deep nerve bundles in the cornea, considerably reducing the risk, severity and recovery time of dry eye*.
Lower enhancement rates
With LASIK at R.K. Netralaya this is only 1% for myopia †. Typical retreatment rates for traditional LASIK are between 4 and 10%.

Post operative instructions
Our heartiest congratulations for having your surgery done at R K Netralaya with the state of art equipments!
Adopt these habits as soon as your procedure is complete:

1. Wear the protective eye glasss for the 3-4 days and when you sleep tonight
2. Rest and sleep as often as possible the first 48 hours
3. Avoid doing very intense exercise for at least 72 hours
4. Keep your hands away from your eyes
5. Protect your eyes from dust and abrasion
6. Relax your eyes whenever possible over the next few months
7. Keep them well lubricated
8. Wear dark, wrap-around sunglasses to shield against bright lights
9. Shower or take a tub bath, but avoid getting anything in your eyes for 3 days after surgery.
10. Avoid all water sports and activities (hot tubs, whirlpools, swimming, etc.) for 2 weeks post-operatively.

Enjoy the new freedom in your life!
Instructions for putting drops
Be careful not to let the tip of the dropper touch any part of your eye.
Make sure the dropper stays clean.
After putting one drop, wait five minutes before putting the next drop. This will allow the first drop to have enough time to act
Tilt your head backwards, gently pull the lower lid down to create a pocket and let a drop fall into it. Try not to squeeze your eyes tightly.
While you should not touch your eyes, you may wipe excess liquid from your cheeks

How Long Does Lasik Surgery Take?
While you should prepare to spend around 2 hours in the hospital for your treatment, the surgery itself takes less than 10 minutes. In fact, the laser will be used on each eye for a few seconds!
Can I Negatively Impact The Treatment? What If I Move Or Blink During The Procedure?
The lasers utilized by us at R K Netralaya (Wavelight EX 500) have advanced eye tracking systems (1064Hz) that ensure the laser is focused on the proper part of the eye. If you move slightly, the laser will be able to track that movement and remain focused on the right spot on the cornea. Moreover, this laser is so fast (500Hz) that the procedure is over in seconds. If you move, the laser has safety features that will automatically shut it down and reposition the laser where it left off. We take every step necessary to ensure our commitment to your safety is reflected in our customized technology.
I am above 40 years old. Am I too old to have LASIK?
Although there's no real "maximum age" for laser vision correction, we would first need to determine that the overall health of your eyes is good, and that your vision difficulties are not being caused by cataracts or some other eye disease. Depending on your age, you may need reading glasses after treatment. Nearly everyone needs reading glasses by their mid-40s. This is known as presbyopia. Presbyopia is a natural change in the lens inside of the eye and is not influenced by refractive surgery. If you are wearing bifocals or readings glasses now, you will still need reading glasses after LASIK. A treatment option with refractive surgery is known as monovision. In a monovision treatment, the patient's dominant eye is corrected for distance vision with their non-dominant eye being left slightly nearsighted. Although not a replacement for reading glasses, this preserves a degree of near vision clarity. At R K Netralaya, we routinely do monovision therapy for those in their forties.
I Have Seen Ads For As Low As Rs. 12,500/eye. How Can Lasik Be So Cheap?
When you're shopping for a LASIK surgery provider, this is one of those instances where "you get what you pay for." It's important to fully understand any possible shortcomings of highly discounted LASIK surgery costs. Be sure to ask questions regarding:

Experience- Find out how many LASIK surgeries the surgeon has performed or how many years they have been in practice.

Laser Technology- There is a variety of antiquated lasers that may be less expensive to use, but may not produce the quality of results. Some are refurbished old machines which are bought second hand and do not give accurate results consistently. Maintenance and calibration of the lasers are also very important in assuring you receive optimal results.

Centre maintenance- Be sure to look around the place of surgery. You could see the cleanliness levels, presence of a full generator and UPS back-up system and a professional system that is taking full responsibility for your eyes.

Reputation- Consider the company's reputation and longevity. Be certain you trust your LASIK surgery provider in a way that is equitable to the importance of your eyes.

Results- Speak to the patients operated at the center. You can also ask for the results which are obtained at the LASIK center.
How safe is LASIK?
The US-FDA has approved LASIK as a safe and effective procedure. It is important, however, to remember that LASIK is not the right choice for everybody. Some people are not appropriate candidates, and if treated could have less than optimal results. At R K Netralaya, you will go through a thorough pre-operative evaluation to determine if LASIK is right for you.
Does LASIK hurt?
No. The actual treatment itself is painless. You will be given plenty of anesthetic drops to completely numb the eye. You may feel a light pressure sensation around your eye, and after the procedure is finished you will feel a sensation our patients describe as gritty or like a lash in your eye for a few hours…but most people experience very little pain. We'll give you a prescription for a pain reliever should you need it, but most people need nothing more than nimesulide and a little rest time.
How accurate is LASIK?
Based on clinical data from FDA for the Wavelight LASIK machine, and our personal experience, LASIK is very accurate. Careful consideration of your needs and a complete preoperative evaluation help us achieve excellent results with the vast majority of our patients. Even with our advanced technology and experience, approximately 1 in 20 patients may need to have a retreatment in one eye to achieve their best uncorrected vision. This is because we are treating human tissue and there is always some variability in how each individual's eye will heal.
I've heard that the laser causes night vision problems…is this true?
Starbursts, glare and halos at night can be caused by several things. The first is when an inadequate diameter area of the cornea is treated. The treated area must approximate your pupil size under dim light. We analyze pupil to make certain that your treatment area is large enough. Also, our machine uses very little corneal tissue and this allows us to treat a larger area of the cornea. The second cause of night vision problems is the use of older generation lasers and poor treatment designs. We custom designs each patient's treatment so that the optimal optics can be obtained using wavefront optimized treatment profiles. These prevent imperfections or spherical aberrations from being introduced into the eye. The new "flying spot" lasers, such as our Wavelight EX500, apply a much smoother treatment and blend the region between treated and untreated cornea better. Very few of our patients report any night vision problems after their first month post-op.
How long will the effect of LASIK last?
In most cases, the treatment effect of laser vision correction is permanent, especially if your eyeglass prescription was stable before treatment. If there is something in your genetics that says your prescription will change in the future, having surgery now will not prevent that from occurring. In our experience, a change like this is very uncommon If necessary though, you may be able to be re-treated many years later should that occur.
How often will I see the doctor following my surgery?
Your postoperative appointments will be scheduled:

1. One day
2. One week
3. One month
4. Three months
5. And six months (optional)
How soon after the surgery will I be able to see?
Visual recovery varies from one day to one week. The majority of patients resume normal activities one to two days following surgery but it may take 1 to 2 months for your vision to fully stabilize. Although everyone is a little different, the vast majority of our LASIK patients achieve legal driving vision or better, the very next day. That is one of the most exciting advantages of the LASIK procedure; clear vision comes in quickly. Initially, your vision might not be crisp and may fluctuate slightly. This is perfectly normal and should improve gradually day by day.



Rapid restoration of vision (within hours of surgery)

Highly predictable

Both eyes can be treated on the same day

Minimal discomfort

Wider range of correctable prescriptions +6.00 to –12.00 diopters

Treatment of Astigmatism up to 6 diopters (and more in selected cases)
