Table 1 Comparison of out-of-plane displacement of human corneas at the central cornea and at the limbus in response to a 0.25 mmHg increase in hydrostatic pressure

From: An interferometric ex vivo study of corneal biomechanics under physiologically representative loading, highlighting the role of the limbus in pressure compensation

Human cornea No.

w at central cornea, mean ± SD (μm)

w at limbal/prelimbal region (N-T axis) (μm)

w at limbal/prelimbal region (S-I axis) (μm)

Mean dw/dx (central 8mm N-T axis) ×1.0e-06

Mean dw/dx (limbus N-T axis) ×1.0e-06

Mean dw/dy (central 8mm S-I axis) ×1.0e-06

Mean dw/dy (limbus S-I axis) ×1.0e-06
