SMILE is the most recent and advanced form of laser assisted refractive surgery. SMILE stands for Small Incision Lenticule Extraction and is creating a revolution in the realm of laser vision correction procedures like never before. SMILE is the first ‘NO FLAP’ technique that makes a small 2mm cut in the cornea to remove a thin slice of corneal tissue unlike LASIK that creates a flap by cutting 28mm circumference of cornea. It uses a single femtosecond laser throughout the procedure unlike LASIK that employs an excimer laser to treat the cornea under the flap. Here the tissue damage especially to the corneal nerve fibers is almost nil as compared to other laser based procedures.
The main advantage of SMILE is that it is flapless and hence there is no chance of the flap moving or folding unlike in LASIK. As corneal nerves are untouched in SMILE the incidence of dry eye is almost nullified resulting in better patient comfort following SMILE.
The small incision and the precision of femtosecond laser in SMILE results in excellent corneal stability. The procedure is also not affected by external factors like temperature and humidity as there is no flap and results in higher treatment accuracy. With SMILE the disadvantages of older laser vision correction treatments are eliminated retaining their advantages.
Calling SMILE a day care procedure may not be right as patients who undergo SMILE are in and out of Uma Eye Clinic in less than one hour.
Visual recovery following SMILE is instantaneous. Patients can return to their daily activities immediately following SMILE, be it even sports like scuba diving or bunjee jumping.
As of the year 2023, the newest update to SMILE has been introduced.
The new version termed "SMILE Pro" takes SMILE to the next level by making the experience even more comfortable and seamless to the patient.
The laser application time in "SMILE Pro" is now only 8 seconds compared to the 22-30 seconds of laser application in the older version of SMILE
SMILE Pro also now included cyclotorsion compensation which is a form of eye tracking which makes correction of high cylinder powers even more precise and accurate
Uma Eye clinic is the first institution in Tamilnadu to introduce this technology to the benefit of our patients.
