ReLEX SMILE procedure crosses milestone of One Million eye surgeries


Carl Zeiss the German manufacturer of Optical and medical instruments recently announced that Ophthalmologists worldwide performing Laser eye surgery using their most advanced refractive technology “ReLEX SMILE” has crossed the milestone of One Million eye surgeries worldwide.

Over 1,300 Eye surgeons worldwide in over 65 countries have already performed over 1 million SMILE procedures done successfully.

Refractive surgery is swiftly transforming the vision correction process world over with impressive results. Common vision problems like nearsightedness, farsightedness, astigmatism, and presbyopia can now be treated with laser technology.

At Drishti Eye Institute, we offer state of the art instrumentation blended with the expertise of highly skilled doctors that ensures utmost care for your eyes.

SMILE is the latest 3rd generation procedure of laser vision correction. It is a minimally invasive, flapless, and bladeless procedure that combines the advantage of the 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 Advantage

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

•  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 aftercare is required, enabling you to enjoy your new visual sensation right from day one.



ReLEx SMILE is an advanced laser technology for the gentle correction of vision defects. It is a minimally invasive treatment method that combines the extensive experience and superior safety of traditional vision correction techniques with numerous innovative benefits, high precision levels, and perceptibility with greater comfort during the treatment itself.

How is SMILE different from other refractive procedures?

Unlike in all other laser eye surgery procedures, the corneal tissue is not ablated using an excimer laser. ReLEx SMILE is totally laser operated procedure that uses proven Femto second laser technique and is absolutely flapless and bladeless. Quick procedure and early recovery are among the other key advantages that SMILE has over other conventional refractive procedures.

Can I get rid of my spectacles/contact lenses permanently after undergoing SMILE?

Yes. SMILE is a permanent treatment. The cornea is reshaped to its ideal shape using femto second laser technology, this corrects the vision forever and the patient need not wear any aid for distant vision in future.

How many patients worldwide have undergone SMILE?

SMILE is a smart solution offered at centers of excellence for vision across the globe. To date, more than 380,000 eyes have been successfully treated with SMILE. The technique is based on the proven femtosecond technology that has been in use for several years and is considered to be safe.

Is SIMLE safe for people wearing contact lenses?

SMILE is an exemplary technique for correcting your vision. It is completely effective and safe for people wearing contact lenses. Although your surgeon might ask you to discontinue wearing contact lenses for a couple of days before surgery.

Is SMILE painful or does it cause any redness or hypersensitivity in eyes?

SMILE is minimally invasive and virtually painless method that does not invoke use of needles or surgical blades. The entire procedure is laser operated and gets over in few minutes. There are no cases of hypersensitivity or redness reported with SMILE.

How long does SMILE procedure take?

Short duration for surgery and early recovery are amongst the many benefits that come with the advanced procedure called SMILE. The entire procedure gets over in less than 12 minutes for both the eyes.

What are the chances of dry eyes?

According to studies SMILE is less invasive and preserves most of the nerves while LASIK having a big flap ( 18mm ) makes significant changes to the corneal nerves. Hence chances of dry eyes in case of SMILE are lesser tha in LASIK.

Can i drive back home immediately after surgery ?

No. For the first few hours after surgery, your eyes will remain sensitive to light and the vision remain blurred therefore driving is not recommendable so soon. You can start driving within a day although you might be expected to put on UV protected sunglasses for few days while going outdoors.

The principal criteria are that the individual must be older than 20 years before undergoing surgery, and that it ought to have been done 6 months or 1 year before the medical examination. Individuals with high refractive errors(>6D) prior to LASIK are to be excluded. Candidates must not suffer from colour or night blindness. Candidates who have undergone LASIK/SMILE and who fulfills all the necessary criteria may be considered for joining defence forces. ( Ref.  )

How soon can i resume back to my work after undergoing SMILE ?
