Many people undergo laser vision correction to get rid of the spectacles and contact lenses. Modern technology has evolved for the betterment of the people. So in this modern era, correction of vision is much easier than before. Many laser vision correction technologies have come up, but they have many drawbacks. So to cover up the drawback of other laser surgery, RELEX SMILE is the newer technology for vision correctness. Many laser vision correctness methods are available today. SMILE laser eye surgery provides faster recovery and long-term benefits. It provides one of the most successful treatments for vision correction.


RELEX SMILE or SMILE stands for Small Incision Lenticule Extraction. It is one of the modern technology used today for the correction of vision. SMILE is mainly used to correct shortsightedness, myopia, and astigmatism, due to an irregularly shaped cornea. With this technique, the shape of the cornea is changed, which helps more light to focus on the retina, giving a clear vision. It reduces the need for lenses for seeing nearby and faraway objects. The recovery is faster after the surgery, so people can get back to work fast. The chances of failure of SMILE laser eye surgery are very rare.


Following are the eligibility criteria for the person undergoing SMILE laser eye surgery-

  • The patient must be of more than 21 years of age.
  • A patient should have good health.
  • The cornea of the patient must be healthy.
  • The patient should have an eye prescription which is not changed for more than a year.
  • If a woman is undergoing SMILE surgery she should not be pregnant or lactating.
  • No infection or injury should be there in the eyes.
  • People with advanced glaucoma can’t undergo SMILE laser surgery.
  • Hyperglycemic patients are not eligible to undergo SMILE laser surgery.


The following procedure is used during SMILE laser eye surgery

  • Before the surgery, the doctor administers an aesthetic eye drops in the patient’s eye for painless surgery.
  • The laser called Carl Zeiss VisuMAX is used, which places pulses of laser on the cornea with accuracy and precision.
  • The pulses then form a tiny bubble layer over the tissue, which is to be removed.
  • The laser makes a small connecting layer over the tissue, which allows the surgeon to remove the tissue. In addition, it assists in altering the shape of the cornea and enhances eye vision.

The complete procedure takes 15-20 minutes, during which Femtosecond laser is used to remove a disc of tissue from the cornea providing clear vision.


Following are the advantages of SMILE over the other surgical methods-

  • During LASIK , the flap is made, but no flap is made in the SMILE laser surgery which reduces the chances of flap dislocation.
  • The complication of dry eyes is minimal in SMILE.
  • The healing period is shorter in SMILE than in lasik.
  • The efficacy of SMILE is very high.
  • The corneal disk of tissue is removed through a small incision, so the chances of corneal damage are less.
  • It is a quicker procedure than the lasik treatment, which completes within 15 minutes.
  • The whole process is comfortable, and after surgery, there is no flap related complications.


With fewer side effects and more benefits, SMILE is one of the best laser eye surgery to correct vision-related problems. SMILE provides a good long-term solution for vision correction with low failure and high success rates. The whole procedure completes quickly, so one can get back to work without much delay.
