We present a numerical procedure for the simulation of the air puff test,
a medical procedure used by ophtalmologists for the identification of the Intra Ocular
Pressure, and potentially useful for the identification of material properties of the human
cornea.
The problem involves the modeling of the cornea, that is a biological tissue, modelled
as an hyperelastic material, and the aqueous humor, that is, the fluid filling the anterior
chamber of the eye, that is treated as a Newtonian fluid, and modelled using a meshfree
formulation, useful for the solution of a Fluid-Structure Interaction problem. Fluid and
Structure are coupled using a Dirichlet-Neumann iterative approach, which permits the
adoption of a partitioned coupling approach and explicit, fast solvers for the different
subproblems.
