Corvis ST parameters measured, first applanation (a), highest concavity (b), second applanation (c). A1DA, corneal deflection amplitude during the first applanation; A1L, length at the first applanation; A1T, time from starting until the first applanation; HCDA, corneal deflection amplitude at the moment of the highest corneal concavity; PD, peak distance at the highest concavity; HCR, central concave curvature at highest concavity; HCDL, highest concavity deflection length; HCT, time from the measurement beginning to the moment of reaching the highest concavity; A2DA, corneal deflection amplitude during the second applanation; A2L, length at the second applanation; A2T, time from starting until the second applanation
