Quantification of the corneas´ biomechanical properties helps to diagnose corneal abnormalities early, which is key in keratoconus (KC) management and treatment. We recently introduced a multi-meridian air-puff ssOCT system capable of acquiring corneal deformation images during air-puff excitation on two meridians. Two healthy and three KC patients were measured with the system. The results were used to quantify deformation asymmetries and as input data for Finite Element (FE) modeling, which was used to estimate corneal biomechanical properties by means of an inverse analysis. Deformation asymmetry parameters and the estimated tangent modulus for healthy and KC corneas are presented and compared.
