How does the corneal flap affect visual outcomes?

How does the corneal flap affect visual outcomes?

A: New science reveals that the corneal flap has been widely underestimated for its affect on the visual outcome of LASIK. If the corneal surface is left with fine aberrations after the cut with the handheld blade, the precision of the excimer tissue ablation, the second step, can be compromised. Eliminating tiny irregularities on the corneal surface, as is possible with Bladeless LASIK, gives a boost to the vision after the procedure.

Surgeons have found statistically and clinically significant differences in the vision patients achieve when the femtosecond laser is used for corneal flap creation. Bladeless LASIK goes beyond simply creating a safer, planar flap to preparing an optimal corneal architecture below the flap, providing for superior visual outcomes, even among patients who undergo wavefront guided procedures. The end result: fewer complications and better vision.

Bladeless LASIK is offered by NVLC-CFS at Mumbai, Hyderabad, Vadodara, Ahmedabad, and Surat.


What is Bladeless LASIK?

What is Bladeless LASIK?

A: Bladeless LASIK uses the VisuMax laser to complete the first step of the LASIK procedure. It is an advancement to make LASIK an all-laser procedure.

Bladeless LASIK is noted for improving the safety and accuracy of LASIK by replacing oscillating microkeratome blade historically used in the first step. Today, Bladeless LASIK is the technology of choice amongst leading LASIK surgeons and ophthalmic teaching institutions worldwide. The VisuMax Laser is the latest generation of a class of lasers known as femtosecond lasers, including the Intralase and FemtoLDV lasers.

Bladeless LASIK is offered by New Vision Laser Centers-Centre for Sight at Vadodara, Ahmedabad, Mumbai, Hyderabad and Surat, besides other centers of Centre for Sight at Delhi, Indore and Meerut.


Why is LASIK a double step procedure?

When laser vision correction was performed without the corneal flap, as in PRK (photorefractive keratotomy), patients experienced considerable discomfort and a delay in visual acuity. So in LASIK, the surgeon first creates a micro-thin flap of corneal tissue and folds it back to prepare the eye for the second step, where an excimer laser is used on the inner cornea to correct vision. This two-step process allows for rapid visual recovery with little or no patient discomfort, and is credited with the popularity and growth of the procedure worldwide.

The differences between different LASIK procedures is on the first step of this two step procedure-how the flap is created. In Conventional LASIK, an instrument known as a microkeratome, which is a hand held, high speed oscillating blade, is used to create the micro thin flap. Most of the complications in the LASIK procedure, have their origins in the use of this hand held blade instrument. Bladeless LASIK, on the other hand, uses a laser known as a femtosecond laser, to create the micro-thin flap. This is also called intralase lasik or i-lasik or femto-LASIK. In Bladeless LASIK, the entire process is automated, and is much safer, more precise and smoother overall for the patient.

Bladeless LASIK is offered by New Vision Laser Centers in Ahmedabad, Vadodara, Mumbai, Hyderabad and Surat, besides other centers of Centre for Sight including Delhi, Meerut and Indore.

Laser Eye Correction Risks

Laser Eye Correction Risks

Following are the Laser Eye Correction Risks. Please note that most of these outcomes are very rare, and in general, most laser eye correction patients do extremely well, and are off to work on th very next day with perfect outcomes.

a) Procedure may not be completed on the same day-generally with bladeless lasik or ReLEx smile, this is unlikely-and may need to be postponed by a few weeks.

b) Undercorrection or overcorrection, resulting in some number being left behind. Generally speaking, we offer a free enhancement procedure to take care of this. Our current enhancement rates are 1-2%. ReLEx smile enhancement rates are about 0.2%.

c) Post-operative infection. Extremely rare if proper care is taken

d) Excessive Corneal thinning. We will not treat patients whose corneas are already too thin. But in some cases, very rarely, excessive thinning can happen despite our best efforts.

e) Night Vision DIsturbances, like glare and haloes at night. Generally, with the best profiles like aspheric lasik or wavefront customized LASIK this is not likely.

f) Another Laser Eye Correction Risk is an eye infection. An eye infection can have disastrous consequences if not treated properly. This is why we advise antibiotic drops prior to the procedure, and after the procedure, and follow the strictest infection control protocols during surgery. Our infection rate is about 1 in 5000.

g) Flap complications-Only likely with LASIK and not with Bladeless LASIK or ReLEx smile.

Other Laser Eye Corrections risks are also possible. Please click the link for more details.


How long does laser eye correction last?

How long does laser eye correction last?

Laser Eye correction works by corneal reshaping, and the shape change is a permanent one. Since the shape change is permanent, laser eye correction is also permanent. So, in general, laser eye correction last’s permanently, The refractive error (or number, in layman’s terms) should not come back following the procedure.

However, this statement should be viewed with some limitations. Laser eye correction may not last permanently if

a) The surgery has been done at a young age (i.e, less than 18 years for women and less than 21 for men)

b) Other pathologies develop in the eye, like a cataract or glaucoma.

c) Other systemic problems occur-for example, if there is pregnancy or diabetes. Refractive errors can also change as a reaction to some drugs. Sometimes contraceptive pills can also cause a change in refractive errors.

d) In a very few individuals, there is some change in power even without any laser eye correction. Such people should expect that laser eye correction will not last permanently in their case.

e) there is an abnormal healing reaction after laser vision correction-normally this will become evident  fairly quickly-around a month or so after laser eye correction. In such a situation, New Vision Laser Centers will perform an enhancement procedure free of charge.

Also, one must remember that laser vision correction is for distance vision correction. Don’t imagine that it will work for age related near vision problems which appear after the age of 40-42. Such people should undergo presbyopic lasik or laser blended vision.

ReLEx smile is a new laser technique offered at only a few centers-which is the most likely not to cause an abnormal healing reaction in the eye and have the most stable correction. ReLEx smile is offered at:

Laser Eye Correction Mumbai

Laser Eye Correction Hyderabad

Laser Eye Correction Vadodara

Laser Eye Correction is offered by New Vision Laser Centers in other cities including Rajkot, Surat, Ahmedabad, Kolkata, Vizag, Kurnool, Bhavnagar and many othet locations.

LASIK Cost Mumbai

LASIK Cost Mumbai

Different LASIK Cost Mumbai

We offer many different types of procedures in our Mumbai LASIK center. Each of them has a different price, and so we must inevitably discuss LASIK Cost Mumbai only in reference to the type of procedure. For more about each type of procedure, you can refer to the relevant pages as linked to this page.

Aspheric LASIK Cost Mumbai: Rs. 25000 to Rs. 35000

Customized LASIK Cost Mumbai: Rs. 40000 to Rs. 55000

Bladeless LASIK Cost Mumbai: Rs. 85000 to Rs. 100000

SMILE Cost Mumbai: Rs. 120000 to Rs. 135000

Corneal Cross Linking Cost Mumbai: Rs. 20000 to Rs. 50000 (per eye).

Corneal Cross linking costs vary based on whether it is accompanied by any topolinking or refractive correction.

Laser Blended Profile for Near Vision Correction: Rs. 5000 (per eye)

The above lasik costs mumbai are for both eyes (unless otherwise mentioned).

Why do we mention a range instead of one single figure? Well, it depends a little on how complex the refractive error is, and the demands of the patient. If you have a high power, or high astigmatism or a thin cornea, or dry eyes, you should expect a figure on the higher side of the range. Also, it depends on the doctor treating you. A more experienced doctor is more likely to charge on the higher side of the range.

Do check at the clinic for any discount schemes we may be running. We often run these, so you might be able to take advantage of the scheme. Do chcck out our facebook page: LASIK Mumbai




President Obama felicitates Indian Pioneer of LASIK surgery

Dr. R. Srinivasan, an Indian-American Scientist, was honored by the award of The National Medal for Technology and Innovation. Dr. R. Srinivasan, along with Steven Trokel first suggested the use of the excimer laser for corneal refractive surgery, which eventually became refined into the procedure we know today as Laser In Situ Keratomeleusis, or LASIK.

For more details, please look at this LASIK article.

Bladeless Laser and Epilasik is not the same as Bladeless LASIK

Bladeless Laser and Epilasik is not the same as Bladeless LASIK

Some doctors, especially in Mumbai, who do not have a femtosecond laser, perform PRK and try to mislead patients into believing that they are performing Bladeless LASIK. In fact, if you are careful, you will notice that they claim Epilasik or Bladeless Laser, not LASIK.

Let us warn patients not to get convinced by such tricks. Bladeless LASIK is done with a combination of a femtosecond laser and an excimer laser, and is a much different and better procedure than that done by PRK, Bladeless laser, Epilasik or call it what you will. Only the excimer laser is used for this procedure, and obviously, it costs much less, because no advanced femtosecond laser is used. Bladeless Laser or PRK has lots of issues, and that is why in most advanced countries in the world, only a small fraction of all procedures done are by this technique. 90% of all laser procedures in the US for example, are done using Bladeless LASIK not Bladeless Laser.

No wonder the cost of Bladeless LASIK is more than that of Bladeless Laser. It simply has more costs for the surgeon, and rightly so, given the improved safety and accuracy profile. Don’t get taken in by con artists, who confuse you with words.
