Small incision lenticule extraction (SMILE) is a relatively new refractive procedure designed to treat a multitude of refractive errors such as myopia, hyperopia, presbyopia, and astigmatism.
The procedure involves using a femtosecond laser to create a corneal lenticule which is extracted whole through a small incision without the use of an excrimer laser.
It is reported to achieve effects similar to laser-assisted in situ keratomileusis (LASIK) with excellent post-operative outcomes.
