At the immediate postoperative visit, the slit-lamp examination allowed the visualization of both flap edges (Figure 1).

Its extension could be also delimited at the slit lamp (Figure 2).
In the lower quadrant, the cut done primarily with the microkeratome opened up from inside after colliding with the new femtosecond flap, leading to an epithelial defect that was visualized with the OCT system.

In the lower quadrant, the primary microkeratome cut opened up from inside after colliding with the new femtosecond flap, leading to an epithelial defect (Figure 3).

In the temporal quadrant, both flaps were clearly positioned at different levels and the abrupt end of the primary mechanical cut was visible in the OCT analysis (Figure 4).
