Figure 2. Laser scanning pattern and incisions created during femtosecond lenticule extraction (FLEx) procedure in the human cornea. A-D: Representative images of specific steps. A: Before the delivery of the laser the eye must be centered and full suction must be achieved. B: Creation of the posterior surface of the refractive lenticule with a scanning pattern in a centripetal direction (spiral in, arrow). C: Creation of the anterior surface of the refractive lenticule with a scanning pattern in a centrifugal direction (spiral out, arrow). D: Edge of the lenticule (long arrow) and creation of the periphery of the flap (short arrow).
