Refractive Surgery



Best Lasik/Smile Eye Surgery & Treatment in Bangalore

There are two steps in the LASIK procedure. First, the surgeon creates a micro-thin corneal flap, which is lifted to expose the inner cornea for step two, tissue ablation by an excimer laser. The first step of making flap can be done either with ultrathin blade call Microkeratome (Blade LASIK) or with laser (Blade free LASIK).

The Femto Second (FS) laser introduced the concept of blade-free LASIK, representing the first improvement to the procedure’s first step. Surgeons have found statistically and clinically significant differences in the vision patients achieve — better than 20/20 to 20/15 and even 20/12.5 — when the laser is used to make the corneal flap.

With its excellent safety profile, patient comfort and superior visual outcomes, Blade free LASIK is among the fastest-growing refractive surgical techniques in the country today. As of the third quarter of 2006, the 518 IntraLase FS lasers in use worldwide have performed approximately one million blade-free LASIK procedures. In the U.S., more than 25 percent of all LASIK procedures incorporate the advanced Femtosecond laser Method.

Narayana Nethralaya has two state of the art Femtosecond laser machines – Wavelight FS-200 & IntraLase™ both providing safety, precision and accuracy.

Wavelight Refractive Suite

Asia’s first refractive suite comprising of both Wavelight FS-200 reducing the flap making time to ‘6’secondsand Wavelight EX-500 with advanced iris tracking system and reduced laser treatment time.

The 4th Generation Intralase FS Laser – Total time: 15-30 seconds

The ultra-fast laser uses an infrared light beam, generating up to 60,000 pulsesper second, to prepare an optimal corneal architecture below the flap.
The department of Refractive surgeries at our hospital is amongst the very few centers in the world equipped with three state of the art and top-line LASIK machines: Zyoptix®, (with wave front guided technology), Allegretto Wave®, with wave front link as well as the latest Pentacam® link) and Wavelight EX-500™ which helps us to individualize patient treatment depending upon their suitability.

Understanding the LASIK procedure:

Using an “inside-out” process, the FS laser is precisely focused to a point within the cornea, where thousands of microscopic bubbles are formed to define the architecture of the intracorneal surface and the resulting flap.
The surgeon controls flap diameter, depth, hinge location and width, and side-cut architecture — factors that can be varied per patient. Bubbles are then stacked along the edge up to the corneal surface to complete step one.
The physician then exposes the prepared corneal bed for excimer laser treatment by lifting the flap. The LASIK procedure is complete when the flap is securely repositioned on its beveled edge.

LASIK with the Femtosecond Laser (FS) is emerging as the gold standard

NASA has approved the use of blade less / FS laser in the correction of refractive errors.

The Blade: Technology from a Bygone Era?

For the majority of top U.S. ophthalmic surgeons and teaching institutions, the FS laser is the technology of choice. Many of tomorrow’s LASIK surgeons are training exclusively using the blade less Method, signifying the potential end of microkeratome use in the procedure. In addition to LASIK, the IntraLase FS laser is the first femtosecond laser cleared for use in a variety of corneal incisions, including advanced corneal transplants.

Prior to the IntraLase laser, LASIK’s first step was done manually with an oscillating razor blade, called a microkeratome. This device causes the majority of LASIK complications and can be unpredictable even in skilled hands.
The flap is then lifted to expose the inner cornea for the second step: vision treatment by the excimer laser.


ReLEx SMILE is a further advancement over LASIK / Femto-LASIK.
ReLex SMILE is a pain free, minimally invasive approach with the advantage of a 100% blade less and flapless laser vision correction. This procedure involves no corneal flaps; refractive changes are made in the intact cornea itself.
The very best for your eyes

    • Flapless
    • Bladeless
    • Painless

Unlike the conventional procedures, ReLex SMILE involves the creation of an extremely thin 3D layer in your intact cornea, corresponding to your refractive number that needs correction. This is then extracted out through a small keyhole incision of about 2-4mm only. As a result, the cornea gets reshaped to correspond to the ideal shape for correct vision. Entirely laser controlled, it is done in a few seconds- precise, safe and comfortable.
