Keratoconus is a non-inflammatory eye disease that causes progressive thinning of the stromal cornea and collagen weakening resulting in a conical corneal shape leading to irregular astigmatism. All currently available treatments do not guarantee predictable outcomes. The GROSSO® implant is a corneal device made of Nitinol alloy, designed to reshape the whole cornea by virtue of a dome-shaped design that follows the physiological curvature. The aim of this thesis is to investigate the mechanical behaviour of the GROSSO® implant through computational simulations performed with Finite Element (FE) Analysis. The investigation focused on two critical situations. The first replicates a crucial phase of the surgical procedure inside the patient’s intracorneal pocket consisting in a 90° folding of the opposite edges of the device (“bending” simulation).
