Coupled Biomechanical Response of the Cornea Assessed by Non-Contact Tonometry. A Simulation Study
Fig 8
Corneal response in the meridional plane (FE results).
Meridional cutting plane of the cornea. a) Displacement field along the optical axis at first applanation time (mm), b) Vertical displacement field at high concavity time (mm), c) Circumferential logarithmic strain field (-) at first applanation time, d) Hoop stress field (MPa) at first applanation time (spherical coordinate system). c) and d) show the bending mode of deformation at which the cornea is subjected during a non-contact tonometry test. Results correspond to IOP = 19 mmHg and material C.
