Keratoconus is a progressive bilateral and asymmetric eye disease of the cornea. It causes progressive corneal thinning and a cone-shaped corneal protrusion, resulting in irregular astigmatism and decreased visual acuity. The management of keratoconus depends on the degree of progression of the pathology. Today, the options available include both non-surgical treatments (e.g., glasses and contact lenses) and surgical treatments (e.g., corneal collagen crosslinking treatments (CXL), corneal ring segment implantation, and keratoplastic). However, these procedures can only limit the progression of the disease, but fail in restoring the physiological curvature of the cornea. The GROSSO® implant is an innovative corneal implant in nitinol that aims to restore the physiological curvature of the cornea.
