SMILE is the latest 3rd generation of laser vision correction. It is minimally invasive, flapless and bladeless procedure that combines the advantage of previous two generations with increased safety and comfort.

SMILE is the latest 3rd generation of laser vision correction. It is minimally invasive, flapless and bladeless procedure that combines the advantage of previous two generations with increased safety and comfort.
ReLEx SMILE is a further advancement over LASIK / Femto-LASIK.

ReLex SMILE is a breakthrough in laser vision correction offering a whole new level of precision, safety and comfort. In fact, you might just experience the world through a whole new lens-your natural ones.
ReLex SMILE is a pain free, minimally invasive approach with the advantage of a 100% blade–free laser vision correction. This procedure involves no corneal flaps; refractive changes are made in the intact cornea itself.

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.

The ReLEx SMILE technique is performed using the highly precise advanced VisuMax femtosecond laser from Carl Zeiss AG, Germany. This laser system has impressed both the patients and the physicians alike with its sophisticated technology and its precision and reliability. ReLEx SMILE using VisuMax promises accuracy down to the nearest micrometer precision.


SMILE Advantages:

  • The cornea surface is left untouched, preserving its biomechanical strength and stability better than other techniques.

  • Inflammation is reduced to negligible as the total laser energy used is up to 10 times lesser than an excimer laser.

  • Likeliness of dry eyes is significantly lowered, since no flap is created.

  • There is no use of surgical cutting instruments and involves no change of equipment during the treatment.

  • Since this procedure is minimally invasive, it involves minimum intervention and therefore less after care is required, enabling you to enjoy your new visual sensation right from day one.

Applanation Tomometry

The Applanation Tonometer from the house of Tisha medical export comes utilized for measuring of intraocular pressure comes engineered for the purpose of complete surface mounting onto the microscope. We have enabled our Tonometer such that it comes to as a mechanism to that comes towards the front for the sake of better clarity and vision enhancement.


Non-contact Tomometer (NCT)

The non-contact tonometer is an applanation tonometer and works on the principle of a time interval. Measuring the time it takes from the initial generation of the puff of air to where the cornea is exactly flattened (in milliseconds) to the point where the timing device stops. It takes less time for the puff of air to flatten a soft eye than it does a hard eye.


Automated Humphery Field Analyzer (HFA-II)


Ultrasound Scan (A & B)

The applications of ultrasound machines are numerous and commonly used for obstetrics, echocardiography and biopsy just to name a few. Ultrasound Machines is a non-invasive way to provide valuable medical details compare to traditional tools and diagnosis techniques. In other word, it has greatly helped medicine become safer and more accurate. Here are some common functions of the process.


Corneal Topography

Corneal topography, often referred to as photokeratoscopy or videokeratography, is a technology frequently relied upon by optometrists in the eye care health field. It uses computerized equipment and analytic software to measure the natural curvature of the human cornea. Using a unique system of concentric rings projected onto a person's cornea, a virtual image is created from which calculations are made to determine cornea curvature.



A pachymeter is a medical device used to measure the thickness of the eye's cornea. It is used to perform Corneal pachymetry prior to LASIK surgery, for Keratoconus screening, LRI surgery [1] and is useful in screening for patients suspected of developing glaucoma among other uses. Modern devices use ultrasound technology , while earlier models were based on optical principles. The ultrasonic Pachymeters traditionally have been devices that provide the thickness of the human cornea in the form of a number in micrometres that is displayed to the user.
