| Name | Description |
|---|---|
| bIOP | Corrected estimate of IOP obtained adjusted for ocular biomechanical parameters |
| PachySlope | The difference in corneal thickness from the corneal apex toward the periphery |
| ARTh | The quotient of corneal thickness at the thinnest point of the horizontal meridian and the thickness increase toward the periphery |
| Peak distance | The distance between nondeformed peaks under the highest concavity |
| HCDefAmp | Pure corneal deformation under the highest concavity |
| WEM-d | The time taken for the linear anterior-posterior movement of the whole eye after maximum displacement of the cornea |
| WEM-t | The length of the linear anterior-posterior movement of the whole eye after maximum displacement of the cornea |
| DA ratio max 1 mm | The ratio of deformation amplitude at corneal apex to that at 1 mm |
| DA ratio max 2 mm | The ratio of deformation amplitude at corneal apex to that at 2 mm |
| SP-A1 | The difference between the strength of the air puff at the corneal surface and biomechanically corrected IOP divided by deflection amplitude at the first applanation |
| SSI | Material stiffness of the cornea |
| BGF | A parameter which represents the possibility of glaucoma |
