The newest and most latest laser vision correction technique in the field of ophthalmology to receive FDA approval is called SMILE. The key distinction between a SMILE treatment and photorefractive keratectomy (PRK) is the absence of an excimer laser. Instead, with SMILE, a lenticule (a tiny portion of corneal tissue) is removed after a femtosecond laser creates a tiny keyhole incision in the patient’s cornea. SMILE combines the advantages of both LASIK eye surgery and PRK by reshaping the cornea to improve eyesight and visual perception. An experienced LASIK surgeon will recommend the best procedure for your unique vision even if you qualify for more than one procedure.
