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.
