Data were presented as correlation coefficients and P values in worse/better eyes. Time A1: Time from start until the first applanation is reached; Length A1: Cord length of the first applanation; Velocity A1: Corneal speed during the first applanation; Time A2: Time from start until the second applanation is reached; Length A2: Cord length of the second applanation; Velocity A2: Corneal speed during the second applanation; Time HC: Time from start until highest concavity is reached; Def ampl HC: Maximum amplitude at the apex of highest concavity; Peak dist HC: Distance between the two peaks at highest concavity; Radius HC: Central concave curvature at its highest concavity; IOP: Intraocular pressure; CCT: Central corneal thickness.
