AbstractThe past few decades have seen a significant advancement in the field of refractive surgery. Laser in situ keratomileusis (LASIK) and its variant, femtosecond LASIK (FS-LASIK) although form the bulk of refractive procedures performed worldwide, is not free from complications, including flap-related complications, postoperative dry eye, denervation of corneal nerves, and biomechanical instability leading to potential corneal ectasia. Small incision lenticule extraction (SMILE) is minimally invasive bladeless technique which circumvents the creation of flap, thereby avoiding flap associated complications seen with LASIK. This review summarizes the current practices and recent innovative advances in SMILE.
