SMILE, also known as the Small Incision Lenticule Extraction is the most advanced eye surgery that reduces the ophthalmological problems reducing the requirements for glasses or contact lenses of the patients. Depending on the style of the procedure, SMILE is also known as the ‘Flapless LASIK’.
SMILE is the most advanced refractive procedure that reshapes your eyes. Unlike the LASIK procedure, SMILE surgeries do not involve any corneal-flaps. Doctors use the laser beam to reshape the internal layers of your eyes without disturbing the surface.
SMILE is done using the Femtosecond lasers.In this procedure, the doctors do not require to cut any flap like LASIK. The area of the incision is minimum. The doctors do not need to hold back the cornea to correct the eye.
Unlike LASIK, there is no risk of displacements or shifting of the flap as a result of rubbing or other physical contact. It can take 20-30 minutes to complete the whole procedure.
Removing the lenticule from the cornea alters its curvature. As the refractive power of the eyes depends on the shape of the cornea, changing it corrects the vision of the eye.
US-FDA has approved SMILE laser surgery to correct myopia (nearsightedness) of about -8.00 diopters. However, the candidates should be more than 22 years old and should not have astigmatism more than 0.5 diopters. Also, the eyeglass prescription of the patient should be stable for a year. There’s hardly any doubt that SMILE is the best procedure that the patients should avail for vision correction.
As SMILE is one of the least invasive procedures, most patients recover quite fast. As the incision does not require stitches, within a few days it heals on its own. Most patients can see well from the very next day and resume driving or return to work within the next 2-3 days. However, it would take about a few weeks to stabilize the vision.
SMILE is the safest laser procedure that the doctors can recommend to you for correcting your vision. The safety measures of this procedure are US-FDA approved.
Yes. The corneal tensile strength of your eyes improves after the SMILE procedure is done. The flapless procedure leaves the anterior stomatal lamellae uncut. This ensures that the cornea remains strong even after the procedure is over.
No. Being the less invasive technique, SMILE leaves a fewer negative impact on the ocular surface which ensures faster recovery. The flapless smaller incision damages fewer of ethe corneal stomatal nerves and subbasal nerve plexus. All of which reduces the occurrence of dry eyes after the procedure is over.
No. Contrarily, if you compare the visual quality of the patients having SMILE with the patients having LASIK, the former ones show higher visual quality. The difference of tensile strength makes all the difference between the visual qualities between these two procedures.
No. The intrastromal lenticule that the doctor removes from the cornea during SMILE is the only corneal tissue that requires removal. The doctors remove this little strip of corneal tissue through a small incision. The length of the incision is smaller than the other prevalent laser eye surgeries as well.
