The SMILE (Small Incision Lenticule Extraction) method is the latest leap in laser vision correction. It is not only a 100% blade-free approach to laser vision correction, but is a step superior to the NoBlade approach of Femto – LASIK.

Eyes are our windows to the world. Having spectacles is not considered a problem but having a clear vision is more than mere aesthetics being marred by the frames of the spectacles. A clear vision gives you the freedom of sight, the luxury of seeing everything firsthand, rather than having to peek through the slides of glass.

When you are getting the option of a spectacles-free life, make the most of it – there is no reason to put it off. To give you freedom from spectacles or contact lenses, Centre for Sight now offers the most advanced approach to laser vision correction.

BEYOND SPECTACLES. BEYOND LASIK. The Future is Here – SMILE

Intensive R&D efforts and giant strides made in technological development have now yielded the most innovative approach yet – SMILE technology – for laser vision correction procedures that are 100% blade free, entail no corneal flap, and offer pain-free eye treatment. If you want to make sure that the procedure you undergo offers you the maximum safety, precision & comfort then your answer is “SMILE” which is the latest in the field of laser surgery for vision correction and has taken vision correction to the next level.

SMILE – The Next Level

Getting rid of cumbersome glasses and inconvenient contact lenses in order to look better and lead a more fulfilling life is always at the back of the mind of those burdened with these unwanted vision aids. However, no matter how ready you are for a life without spectacles or contact lenses, the decision to undergo laser vision correction is a big one. People who hid behind thick glasses or had to put up with the discomfort and inconvenience of contact lenses, gained a new lease of life with the advent of laser technology powered LASIK. But with sight being one of the most important faculties, apprehensions still remained and decisions were deferred. The hunt was on for a procedure that would offer maximum safety, precision and comfort. The answer lies in SMILE laser technology.

The SMILE method is a step superior to the ‘No Blade’ approach of Femto-LASIK. In Femto-LASIK, a laser is used to create the corneal flap, which is then folded back by the surgeon to perform the LASIK procedure. Although more advanced than traditional microkeratome blade LASIK, it still necessitates the creation of a corneal flap in the eye.

On the other hand, SMILE technology is a 100% blade-free laser vision correction method that enables the surgeon to perform laser vision correction without any corneal flap at all. This means that there is no danger of the flap getting displaced, either immediately after the procedure or even years later, and as the corneal surface cells hardly gets disturbed during the procedure, the patient feels minimal pain and discomfort. This makes SMILE laser surgery the best procedure for spectacle removal till date.

SMILE – Unmatched Precision and Safety

During SMILE, tiny pulses of laser light, about one quadrillionth of a second each, pass harmlessly through the outer portion of the cornea and form two uniformlayers of microscopic bubbles just beneath the surface of your eye. This defines a “lenticule” within the cornea, which corresponds to the number that needs to be corrected. The exact dimensions of these two layers of bubbles are determined by the surgeon based on what’s best for the eye and the refractive error to be corrected. Immediately after the lenticule is created, the surgeon separates the two tissue layers and quickly extracts the lenticule from the cornea, through an incision which is only 3-5 mm wide. You may experience some foreign body discomfort or a little pain for a couple of hours, but you can resume all normal activities almost immediately after the procedure. The whole process is computer controlled for maximum precision to limits that are not attainable with any hand-held blade and the process takes only 20-30 seconds per eye.

SMILE – Now in India

SMILE laser surgery entails considerable investment and specialisation, and hence is offered only in the best laser centres across the globe. Every eye is unique, that is why we tailor our treatment exactly to your eye’s specific needs in order to get the best possible outcome. With the first ever single incision SMILE, a flapless laser vision correction procedure, performed at Centre for Sight in 2008, Centre for Sight has pioneered the innovative SMILE laser surgery in India. With over 46 centres and 28 LASIK laser vision correction facilities, Centre for Sight is Asia’s largest LASIK network and was also the first to introduce FEMTOSECOND LASIK in South East Asia. With the introduction of this technology in its Delhi centre, CFS is now the preferred destination for  SMILE laser surgery in Delhi.

It’s truly time to say goodbye to spectacles…with a SMILE! layers of microscopic bubbles just beneath the surface of your eye. This defines a “lenticule” within the cornea, which corresponds to the number that needs to be corrected. The exact dimensions of these two layers of bubbles are determined by the surgeon based on what’s best for the eye and the refractive error to be corrected.

SMILE – Enhanced Safety, Improved Vision

For anyone looking for blade-free laser eye treatment that is safer and more precise than any other LASIK, SMILE laser surgery is the answer. There are many advantages of opting for SMILE over the conventional LASIK treatment which include:

  • No corneal flap creation – no risk of displacement: As a flap does not need to be created, there is absolutely no risk of flap displacement or complications occurring.
  • Less Dry Eyes: The tiny incision ensures there is minimal cutting of corneal nerves, leading to less dry eye and improved corneal sensitivity after the procedure.
  • Better Corneal Biomechanics: Since the lenticule is removed from a small incision, there is minimal loss of corneal biomechanical strength.
  • Greater Precision and 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 up to 10 times lower; inflammation is less; and there is greater stability of the result. While an Excimer Laser is dependent on atmospheric humidity and other conditions, the Femtosecond Laser is much more robust.
  • Fully automated for quick procedure: The computer controlled process takes only 20-30 seconds per eye.
    • Overall better quality of vision reported by patients: SMILE laser surgery has delivered outstanding visual results with more patients achieving 20/20 vision with SMILE than with any other method.
    • Enhanced ability to see clearly even in low light: Patients are able to see much better in dark, even at dusk or at night.
