Fig. 01 Photographs of the video captured by Corvis ST during the phase of resistance of the cornea to the air pulse (left) and the recovery phase after the cessation (right). On the image, some of the parameters measured during the first applanation, maximum concavity and second applanation, have been drawn in yellow.

Fig. 02 Sign observed at the dynamic response of the cornea after SMILE surgery which is a brightness inclined fringe that appears in the peripheral corneal peaks at the highest concavity stage, moving to the corneal periphery until its disappearance during the outward stage.
