Photorefractive keratectomy is a type of refractive surgery to correct nearsightedness, farsightedness, and astigmatism.
SMILE, is also known as Small Incision Lenticule Extraction surgery and is considered to be the most cutting-edge laser eye surgery for the correction of myopia (near-sightedness) providing LASIK-like outcomes but in a less invasive procedure.
During a SMILE procedure, our surgeon use computer guided, highly focused but soft and light laser light to cut a tiny incision in the cornea and then use it to remove a small piece of corneal tissue (called a lenticule). This reshapes the cornea and corrects your vision.
LASIK, this discomfort will be felt for only about 2–3 hours with a slight burning sensation. No pain medicine is necessary, however, if the Ophthalmologist has suggested some eye drops then you should used it as it improves healing and decreases any chances of infection.
But do not under any circumstances, touch or rub your eyes, especially for the first 24 hours as it will adversely affect your healing.
