Abstract:In modern society, the most popular surgery for correction of myopia and myopic astigmatism are small incision lenticule extraction(SMILE)and femtosecond assisted laser in situ keratomileusis(FS-LASIK). FS-LASIK is widely accepted by myopic patients and corneal refractive surgeons for its excellent safety, efficacy, stability and predictability. With the use of femtosecond laser, SMILE makes the corneal refractive surgery enter a full femtosecond era and become one of the most popular refractive surgery in the world, which is a novel minimally invasive corneal refractive surgery and characterized by flap-free, minimally invasive, small incision, femtosecond. But there is still some controversy about visual acuity, stability of diopter, corneal high order aberration, contrast sensitivity, dry eye, corneal biomechanical property and complication after SMILE and FS-LASIK in correction of myopia. This article reviews the advantages and disadvantages after SMILE and FS-LASIK in correction of myopia and myopic astigmatism among all above mentioned aspects.
