Overview of the docking processes with three femtosecond lasers. (a) Victus: suction ring applied to a sample and curved applanation cone attached to the laser head (left); laser head lowered onto the sample with vacuum on the suction ring (right). Note that, in the actual procedure, the ocular surface is moist. (b) Catalys: suction ring and application of the liquid interface (left); laser head lowered onto the ocular surface with vacuum on the suction ring (middle, right). (c) LDV Z8: suction ring and application of the liquid interface (left); manual docking of the laser handpiece with vacuum on the suction ring (middle, right). Note that surgeon's gentle support of the laser handpiece is needed throughout the procedure.
