Assessment of Corneal Biomechanical Properties by CorVis ST in Patients with Dry Eye and in Healthy Subjects

Table 2

All biomechanical parameters derived from CorVis ST.

CorVis ST parameters	Means
A1-time	Time from starting until the first applanation
A2-time	Time from starting until the second applanation
A1-length	Cord length of the first applanation
A2-length	Cord length of the second applanation
A1-velocity (A1-V)	Corneal speed during the first applanation moment
A2-velocity (A2-V)	Corneal speed during the second applanation moment
Highest concavity-time (HC-time)	Time from starting until HC is reached
Peak distance (PD)	Distance between the two peaks of the cornea at HC
HC radius	Central concave curvature at HC
Deformation amplitude (DA)	Maximum amplitude at the highest concavity
