ReLEx Smile

Small incision lenticule extraction (SMILE) is a relatively new refractive procedure designed to treat a multitude of refractive errors such as myopia and astigmatism.It is reported to achieve excellent post-operative outcomes. This treatment is available in only a few laser eye surgery clinics worldwide and is available in Lotus-Peelamedu branch and another in Kochi branch.Patients get all the benefits of LASIK – rapid healing and very little discomfort – but now without having a corneal flap.

SMILE is being touted as an alternative to LASIK and advertised by some eye surgeons as “flap free Lasik”.ReLEx smile is a breakthrough in laser vision correction offering a whole new level of precision, safety and comfort. The procedure, is the first and only bladeless and flapless minimally invasive 3D technique to visual freedom.


During the procedure, eye anaesthetic drops are used to completely numb the eye, and the state-of-the-art Carl Zeiss VisuMax laser places a series of precise pulses in the centre of the cornea with extraordinary 3D placement accuracy. These pulses form bubbles that are less than 1/100th the width of a human hair, and which outline the tissue that needs to be removed to effectively change the shape of the cornea.

The laser then creates a tiny connecting tunnel through which the surgeon draws out this tissue.

With ReLEx SMILE, no flap is created, so the healing time is faster than conventional LASIK. The procedure takes a matter of minutes, and the vision is80% better instantlyand reaches 100% within a few days.



ReLEx SMILE is most suitable forshort-sighted patients, especially those who may have been told they were not candidates for Laser Eye Surgery because of thin corneas, dry eyes, or contact lens intolerance.

Differences between ReLEx and LASIK

ReLEx represents the beginning of a new era in refractive surgery, on the grounds of its significant advantages in thepatients comfort. Because there is no need to pass from one instrument to another as in the LASIK procedure there is no need for the patient to change their position. This is the main reason why the procedure only takesa few minutes.


ReLEx SMILE is beneficial for those with of myopia (Short sight) between -0.5 D to -10 D and Cylindrical Power (astigmatism) of up to -5D.

An ideal candidate would be:

  • Above 18 years of age
  • Power should be stable for one year and your eyes should be healthy otherwise
  • Through examination and few special tests will be carried out to assess the suitability of your eyes


  • No corneal flap. Therefore there is no risk of future flap shift if there is trauma/injury to the eye.
  • Theoretically stronger cornea.
  • Possibly less corneal dryness, because less nerve fibers are disrupted.
  • The ReLex SMILE procedure is a bladeless, flapless,painless procedure.
  • Safety for High risk jobs and contact sports
  • No Microkertaome blade complications
  • Vision recovery is quick
  • Can return to daily activities within a day
  • Likeliness of dry eyes is significantly lowered
  • involves no change of equipment during the treatment
  • Less after care is required
  • Inflammation is reduced to negligible levels
