 The method of extraction can be via a LASIK-type flap, but more recently a flapless technique makes a small tunnel incision in the corneal periphery.Currently in the US the procedure is only approved for nearsightedness.After the femtosecond laser has separated the lenticule, a blunt spatula is inserted through the incision between the lenticule and the stroma and carefully rotated to ensure that the lenticule is completely detached prior to removal by forceps.
