Minimally invasive surgery for correcting vision
SMILE, Small Incision Lenticule Extraction, uses a femtosecond laser system with high precision and speed to reshape the cornea. The laser creates a small lens shaped pieces of corneal tissue known as lenticule, inside the cornea. It takes an average of 23 seconds. The surgeon then removes the lenticule through a small incision at the front part of the eye. This reshapes the cornea and corrects the refractive error.
SMILE is the most recently developed method of laser eye surgery. This advanced procedure allows the minimally invasive correction of some vision defects. By May 2017, SMILE had corrected myopia and/or astigmatism in more than 1 million eyes in over 60 countries worldwide.
SMILE may be an option for many people with a variety of vision impairments – from mild refractive errors to severe nearsightedness and astigmatism.
