This is one of the fastest Lasers available in India which can correct 1 Diopter in less than 2 seconds.

The tracker for this Laser follows the Eye movements more than 1050 times a second. No eye can move fast enough to fool this eye tracker – extreme accuracy of spot placement is the result.

The tracker tracks sideways eye movements as well as circular movements of the eyeball called “Dynamic Cyclotorsion” which no other Laser can do.

Even movements of the eyeballs back and forth out of the Socket (the human eye cannot see the movement it’s so tiny) can be tracked. No other Laser can do this.

This is called 6 Dimension tracking and is a reason why this treatment is so accurate.

Extremely Stable Laser Energy. This is the Rolls-Royce of Lasers and there is at present nothing better in India for treating complex numbers and complicated eye movements.

This  “AMARIS” was launched  at the ESCRS Congress (European Society of Cataract and Refractive Surgeons) in Stockholm. .“With the SCHWIND AMARIS, we have developed an absolute state of the art system”, says CEO Rolf Schwind.

In this laser, for the first time, there are what is known as 3 fluence values. Fine correction takes place with a low fluence level, improving the resolution. With this intelligent process, the laser treatment time is significantly shortened.

Basically the Laser uses less Cornea than any comparable system.

Online Pachymetry-means that during the procedure itself the laser is actually checking how much cornea is left behind so at no time can we exceed the safe limit.

An eye tracker must work at a significantly higher frequency than the laser in order to safely allow a very short ablation time. The SCHWIND AMARIS’ 1050 Hz turbo eye tracker, with a response time of fewer than three milliseconds, serves to provide unsurpassed precision in the positioning of each laser pulse. This assures maximum accuracy.
For millions of people all over the world who wear glasses and have always yearned to be without them, LASIK is a dream come true. Just imagine getting up in the morning and not having to grope for glasses, or indulge in the fumble of putting on contact lenses. Imagine having to play games without worrying about the glasses being dislodged. Imagine the wonderful freedom of taking part in water sports and not having to worry about the glasses getting soaked and unable to see through them or having contact lenses suddenly dislodged and you have a clear picture as to what LASIK can really do for you. In many ways, it is like a miracle.

The SCHWIND AMARIS 500

The ability to experience superb vision for literally 24 hours a day can be a marvelous experience, and this great dream can come true for you, and to that too, in literally, seconds LASIK has the ability to correct not only corrects nearsightedness, farsightedness, and astigmatism but also can correct, with equal ease, irregularities of the cornea.

Dr. Cyres K Mehta has been specially trained at the Schwind factory in Kleinostheim, Germany for this procedure and has written many chapters and articles on the technique in international textbooks of eye surgery. He has lectured worldwide on his system of doing LASIK.

The term is an acronym for Laser-Assisted in Situ Keratomileusis. It represents the simple technique of raising a very thin microscopic flap of the clear membrane of the eye, the cornea, and then simply applying a gradated quantum of laser under the flap.

Why has LASIK become so popular all over the World?

LASIK has a big advantage that it is a painless procedure.

The flap is simply lifted up, rolled out of the way and the Laser is applied. The laser utilizes an ultraviolet light beam to very accurately remove the tissue from the cornea, literally resurfacing the cornea in the new shape desired which will eliminate the spectacle power. The flap is put back in place and the procedure is over.

• LASIK is a surgical procedure intended to reduce a person’s dependency on glasses or contact lenses and not, as is usually thought, designed to totally eliminate the spectacle power, which is often, impossible.
• The accuracy of the post LASIK residual power is based on many factors like pre-operative high myopia or high astigmatism or corneas which are not perfectly symmetrical. The power will reduce to the level where you may not need to use glasses for over 85% of the time, but some residual power is to be expected.

LASIK is for all practical purposes a painless procedure though you will feel a little tightness and mild discomfort when the initial clip is used to open the eyelids, and when the Microkeratome makes your initial flap (though completed in 6 seconds flat with the new Carriazo Microkeratome.

If you choose you can use the latest Femtosecond Laser for totally Robotic Bladeless LASIK at a very competitive price.

If you decide to go ahead with LASIK surgery, you will need to be evaluated in detail as to whether your eye is fit for LASIK surgery. This is termed as a “Baseline LASIK evaluation”.

It is mandatory that the use of contact lenses be discontinued and switch to wearing your glasses, full-time prior to the initial examination, termed the “baseline evaluation”.

Contact lenses tend to change the shape of your eye. Especially if you have been wearing the lenses for a prolonged period of time. Especially with high powered lenses and RGP or hard lenses the cornea literally molds itself to the shape of the lens. After the lens is removed the cornea gradually reverts back to its resting stage. If LASIK is done too soon the cornea will change in shape and lead to irregular results. It also produces inaccurate measurements which lead to an inadequate result. Often one is hasty in wanting to do a LASIK procedure fast and most contact lens wearers do not want to be seen in glasses but it is a wise precaution and makes sense.

• Soft contact lenses, for at least 2 days before your evaluation and surgery.
• Toric soft lenses, should be stopped at least 8 days prior the procedure.
• ERigid (hard) or gas permeable (RGP) lenses, you should stop wearing them for at least 1 week before your initial evaluation.
• The doctor will carry out a full eye examination including a retinal evaluation to be sure your eyes are normal in every way. You should be careful to tell him about your past and present medical and eye conditions, any history of trauma, infection, red eyes, hazy vision, and about all the medications you are taking or you may be allergic to.

The primary test. This instrument enables a very accurate map of the cornea to be plotted out almost like the whorls and grooves of the fingerprint. This is individual to each eye and forms the basis of the entire procedure. The keratometer evaluates the cornea for any irregularity or any surface defect and looks for keratoconus or coning of the cornea which would preclude LASIK, with an automatic detection system.
The Optikon Computerized Corneal Topographer utilizes a very sophisticated system that has an illuminated small cone with 28 mires (or lines) which reflect on the corneal surface and analyze almost 80,000 points on
the cornea. It covers 90% of the corneal surface in normal eyes and has the resolution of +/- 0.01D with an accuracy of 1 micron.
It has a very sophisticated focusing device using a high-resolution CCIR camera giving a superb Eye Positioning Control System (patented), automatic acquisition, with decentration correction.
The topographer gives us information which is fed into the laser computer

Here a machine called an OCT uses a laser beam that measures the cornea all over to see how thick it is. This is very important indeed and tells us if number removal is safe for a particular number and eye.

Using the new COAS Shack-Hartman System a Helium-Neon laser is reflected and focused on the subject’s retina for hardly 0.5 seconds. The laser reflects out from the retina through a series of very fine lenses (called Lenslets) and is imaged on the computer. By measuring the difference between the beam going in the eye as compared to the one which has emerged, the aberrations (or optical irregularities) are measured and quantified. Using the wavefront map generated by the computer to do an Excimer laser correction also called wavefront-guided LASIK, gives the patient the best chance of achieving 6/6 vision as well as an improvement in quality.

This is a very new machine that sees the eye s cornea in 3D, layer by layer.
Dr. Cyres K Mehta was the FIRST in Mumbai to install this Angio-OCT AVANTI system at his center.
No case of LASIK is done without a full Corneal OCT measurement and evaluation.
The OCT uses a laser beam that measures the cornea all over to see how thick it is. This is very important indeed and tells us if number removal is safe for a particular number and eye.

The entire procedure is very fast. You will be given a cap to wear and requested to lie under the Excimer Laser operating microscope.

Numbing drops will be put in the eye. You will be asked to keep your eyes shut as the outside of the eye is cleaned with Betadine (antibiotic) solution and then dried again.

As a next step, a smooth clip will be placed to keep the lids apart. You will be asked to open your eyes as wide open as you can. There is no pressure on the lids at all.

Then a small suction ring is applied on the white of the eye to immobilize the globe at the time of lifting the very fine flap. You will only feel a little tightness, but there is no pain, or for that matter, even discomfort.

Here the flap is made by laser and not by a blade.

Since most of the procedure is carried out by laser and robotics the procedure is called Robotic Bladeless LASIK.

The laser makes a clicking sound and will stay on for anytime between 2 to 15 seconds depending on the power of the eye which is to be corrected. You will feel nothing.

Each individual pulse of the laser is designed to remove a very fine quantum of tissue. Since with wavefront or topo controlled LASIK, the data has already been fed into the computer of the Excimer laser, it will do exactly the correct amount and automatically stop.

The eye will then be well washed with a balanced salt solution, the flap aligned back into place and then a bandage contact lens is placed on the eye. The bandage lens makes sure that the flap exactly sits back into place and no dust or dirt can get in.

The antibiotic solution is then applied and the procedure for that eye is over. After both eyes are completed, you will be asked if you feel OK and then you walk out of the laser room with a new vision.

• There is always a tendency to feel a bit itchy and a little poky in the operated eyes. Often one eye seems to be more than the other. Though you will feel no pain, they may feel a bit heavy for some time. All this is normal. The eyes will also have a tendency to run with a little water for at least 4 hours after the LASIK procedure. Please do not worry, It’s fine.
• The vision will be a little blurry for the first 4 hours and then gradually settle down. You will be given some tablets to take to make it more comfortable for you.
• It is also important that you do not rub your eyes as rubbing will dislodge the bandage contact lenses and may even misalign the flap below.
• The whites of your eyes may have a few fine red spots on it following the laser. This again is quite normal and occurs due to the suction ring which was placed on the eye. These go away in 10 days and are of no significance.
• You will be given antibiotic / anti-inflammatory eye drops to take at home to help prevent infection and/or inflammation, and will also be advised to use artificial tears to help lubricate the eye.
• You can have a head bath and even wash your face after 4 days following the LASIK, but please no eye make up for 15 days following the LASIK and no kajal and Surma for 10 days following the procedure. Try to avoid using any creams or lotions around the eyes for 15 days and do not go for a swim for a month. Naturally, you will avoid contact sports like football karate and jujitsu for at least 3 weeks.

The speed at which the vision returns is very much dependant on the power which has been corrected and the complexity (associated astigmatism and irregularities on the cornea). Simple powers up to -4.00 usually recover very fast and in a period of 5-7 days, quite good vision is attained and the vision is stable.

In higher powers, the computer has in its software designed to overcorrect by 5-7%. This is because in higher powers in a period of a month, a certain amount of power returns. After this small component returns it remains stable. Based on the experience of over half a million cases done all over the world on this laser, the software built into the Laser does the appropriate correction. Thus for the power of -10.00, an overcorrection of 0.7 would be done which over a month or 6 weeks gradually recedes so that at the end of the period you are left without any power. This also means the for the 1st month, reading will require you to take your reading material or your mobile a little further then you would normally do so and the vision will remain a little misty for distance. All this is quite normal and will recover in due course.

Following power correction of more than 7.00D, even if wavefront controlled, some glare, haloes around point sources of light and a little difficult in driving is normal but usually settles down in about 2-3 months after which time usually it is not noticeable.

LASIK has achieved exceptional success all over the world. As can well be expected, different eyes have different indications. There are three types of LASIK services we can offer you at the center.

Basic LASIK is a good basic technique for correction of low powers (<3.00D)in myopia (near-sightedness), hyperopia (<2.00) (far-sightedness), and astigmatism (<0.75) and has good results. Here the data is directly fed onto the Excimer laser without going through any intermediary steps. For low powers, the results are more than adequate. This also is comparatively more economical.

This is simply the best LASIK untouched by human hand, anywhere in the world. Accuracy safety and reliability is unparalleled.

The entire procedure is done by a robotic arm controlled by the surgeon. It’s just like a science fiction movie.

The arm comes over the eye and is held in place by suction. Then a laser beam makes the flap and the arm goes back. The Dr applies the laser guiding the machine.

The entire procedure is over in 2 minutes.

This is the choice of celebrities, movie stars, professional cricketers, captains of industry, etc who spare no expense on their eyes.

When is LASIK not for you?

You are probably NOT a good candidate for refractive surgery if:

• Career Requirements: Some professions do not permit the use of LASIK. The Armed forces in the USA will accept ROBOTIC BLADELESS but not regular LASIK.
• Cost is an issue: Mediclaim medical insurance will not pay for refractive surgery. As it is classified as a cosmetic procedure. On the other hand, some Mediclaim providers permit it for one eye if the power is more than 7.00D. Ask your Mediclaim provider before undergoing LASIK.
• Repeated changes of spectacle power over the last year. This type of instability tends to occur in the earlier age group.
• Appearing for or have to appear for major examination where excessive night-time study is involved
• Pregnant or breastfeeding.
• You have an illness that may affect wound healing. Certain conditions, such as autoimmune diseases (eg. lupus, rheumatoid arthritis), immunodeficiency states (eg. HIV) and unstable diabetes, and some medications long term use of steroids and retinoic acid may prevent proper healing after a refractive procedure.
• You are not an adult. Currently, no lasers are approved for LASIK on persons under the age of 14 years unless it is done for therapeutic reasons (unilateral amblyopia with corblyopia)
• It is not advisable to undergo LASIK if you have or have had eye diseases, such as uveitis/iritis (inflammations of the eye)
• Eye injuries or previous eye surgeries unless carried out for polishing and smoothing as after keratoplasty or corneal trauma with surface irregularities.
• Keratoconus is a complete contraindication unless following or in conjunction with U-Vex laser (see keratoconus)
• Herpes of the face or long-standing face or lid infections.

• Thin Corneas. The cornea is the guiding tissue for doing PRK or LASIK. It is measured with an OCT, a device that measures corneal thickness in microns. Since with all corneal shaping procedures, the tissue is removed, the quantum of a residual thickness (Which should always be 250u) is important.
• Previous refractive surgery (eg. RK, PRK, LASIK). If previous surgery has already been done, enhancement may not be possible if there is inadequate tissue or there is some problem.
• Excessive dry eyes. Are always a relative contraindication but there will be tests to see how dry it is. Very dry eyes should not undergo LASIK, here SMILE is much better for them.
