Ex-vivo techniques

To-date, almost all quantitative information on the mechanical properties of the cornea has been derived from laboratory-based studies. Most studies undertaken have focussed on determining corneal elasticity, often reporting a single elastic modulus for the cornea. For the reasons discussed in the previous section, this does not provide sufficient information to give a comprehensive understanding of corneal biomechanics, and due to a combination of all the factors discussed, can lead to confusion due to the different nature of elastic moduli reported (Youngs, tangent, secant) contributing in-part to the large discrepancies in reported values of corneal elasticity, some of which are summarized in Table 1[1].
