First Experience in Small Incision Lenticule Extraction with the Femto LDV Z8 and Lenticule Evaluation Using Scanning Electron Microscopy

Figure 1

Incision geometry of the SMILE procedures by the two femtosecond laser platforms. (a), (b) The geometry of incisions which were created by the Femto LDV Z8; (c), (d) The geometry of incisions which were created by the VisuMax. 1, incision for cutting the posterior surface of the lenticule; 2, lenticule sidecut; 3, incision for cutting the anterior surface of the lenticule; 4, one of two incisions for opening cap by Femto LDV Z8 (usually used for identifying one side of the lenticule surface); 5, the other of two incisions for opening cap by Femto LDV Z8 (usually used for identifying the other side of the lenticule surface); 6, the flat contact glass of suction system in Femto LDV Z8; 7, the only incision for opening cap by VisuMax (usually used for identifying the two sides of lenticule surfaces ); 8, the curved contact glass of suction system in VisuMax. Pink areas indicate the lenticules after SMILE surgeries.
