  • creating a lenticule in a stroma of a cornea, wherein creating the lenticule includes creating an anterior lenticule incision and a posterior lenticule incision with a femtosecond laser, wherein the posterior lenticule incision has a central region and a peripheral region, the central region having increased curvature relative to the peripheral region; and

    removing the lenticule from the stroma, wherein removing the lenticule increases the curvature of a central portion of an anterior surface of the cornea with a central elevation change for near vision,wherein removing the lenticule creates a central corneal bump with a thickness that is 3-7 times the central elevation change in the anterior surface of the cornea.
