SMILE (small incision lenticule extraction) is a surgical procedure that works by reshaping your cornea. SMILE uses a femtosecond laser to cut a small incision in the cornea .This focuses light accurately on your retina, giving you sharp vision. SMILE is a relatively new & advance alternative to regular LASIK procedure.
Unlike SMILE, LASIK is a two-step process. It uses two lasers to reshape the eye. First, an excimer laser is used to create a tiny hole. Then, a femtosecond laser cuts into the eye to reshape it. SMILE is a less invasive procedure than LASIK, therefor lowering risk of complications.
