SMILE Eye Surgery

The SMILE eye surgery is a short form for Small Incision Lenticular Extraction. It is a highly advanced technology of blade-free laser vision correction, with even more precision than Femto-LASIK procedures that are widely done.

While Femto-LASIK surgery still uses a laser procedure to create the corneal flap, SMILE does not have any need of the corneal flap. The surgeon performs the procedure without having any effect on the cornea cells, inflicting hardly any pain or discomfort during or after the surgery is done. SMILE is different from previous treatment methods because it is a one-laser surgery. Unlike LASIK or PRK, the reshaped cornea improves the vision of the patient.

It is a fully automated next-generation procedure that is completed in a short time to give long-lasting and stable results. The chances that a patient might require retreatment are very low in comparison to other blade-free LASIK procedures.

Those who have a stable power and want to get rid of specs or contact lenses can get SMILE vision correction. It is used most for correcting myopia, showing excellent results and improved vision. Aside from myopia, it can also be used to treat mild astigmatism, with cylindrical power up to -0.5 only.

Is SMILE surgery safe?

The latest and advanced SMILE procedure is safe and effective in correcting eye problems. This extraction surgery has been done since 2012 and has been done officially in the US since 2016. It is now an FDA approved procedure done on patients from the ages of 18 to 40 years. SMILE is performed only after the tests are done to gauge the condition of the eye. Centre for Sight ensures safe practices for all its testing and treatments, as is the case for SMILE eye surgery.

The incision made during SMILE is only 2mm wide, far less invasive than the 20mm one made in LASIK or the 8mm one done during PRK procedures. This also reduces the disturbance that corneal nerves suffer in other surgical procedures.

Another point in favour of SMILE is that there are almost no post-surgery complications because no corneal flap was created in the operation. With overall better cornea biomechanics, this key-hole surgery ensures speedy recovery of the patient.

Your eye is anaesthetized before the surgery and then prevented from blinking or closing with the help of a speculum. The surgeon utilizes Femto laser technology to create precise lenticular surfaces in the cornea and later removing the lenticule through the incision.

The whole process is finished under 15 mins, with the laser being used only for a small time and the patient left without any discomforts. The patients are free to go back home after being checked by their doctor once again after the surgery.

The SMILE eye surgery technology was specially devised to lessen the occurrence of dry eyes along with reduced strength of cornea. It is suggested in a number of surveys that it helps in resolving issues that people have previously suffered from.

  • Less Invasive
  • Uncomplicated
  • Blade-free and Painless
  • Quicker Surgery & Recovery
  • Better Results

The recovery from SMILE surgery is slower than the recovery from LASIK or other similar procedures. It is due to this, patients often miss out on the instantaneous experience of seeing better in just half an hour of a laser vision correction operation. With highly sophisticated technology and infrastructure that Centre for Sight offers, the patients get the best service and care.

The whole surgery is carried out without causing any pain or discomfort to the eyes. The recovery time is also very fast, which allows you to adjust to the changes very quickly.

How quick is the recovery after SMILE?

The recovery time is different for every patient, but on average, most people can get back home the very next day after surgery. It is a quick and hassle-free recovery.

SMILE eye surgery was developed to minimise the complications that used to happen in previous surgical techniques. Nowadays, post-operation issues are almost zero and the whole process is pain-free.

Is SMILE a laser surgery?

SMILE eye surgery is a blade-free one-laser surgery. This means that throughout the procedure, the laser is only used once.
