Figure 3. Surgical steps in Femtosecond lenticule extraction (FLEx) A: Dissection, opening and lifting of the flap (arrow). B: Once the flap (short arrow) is flipped, the edge of the lenticule (long arrow) and the plane of the posterior surface of the lenticule are identified. C: The lenticule (arrow) is separated and removed from the cornea. D: After extraction of the lenticule, the previous location of the lenticule edge (arrow) can be identified in the surface of the stromal bed just before the flap is repositioned.
