1. A ring-shaped corneal implant having shape memory for implantation in the cornea of the eye, wherein the implant spans an implant plane (8) in a starting state, and wherein the implant is transferable by application of a compression force (F) in the implant plane (8) from a starting state into an intermediate state, in which lateral dimensions of the implant, measured in the force direction, are smaller than lateral dimensions of the implant in the starting state, wherein an alignment of an implant cross-section (1) in the intermediate state is pivoted at least in one pivotable longitudinal section along a circumference of the implant by an angle (α) around a circumferential axis (5) of the corneal implant in relation to the starting state,
wherein the corneal implant is both geometrically and mechanically closed and does not have a discontinuity,
wherein the corneal implant is formed from a polymer plastic comprising polymer molecules, and wherein the corneal implant has a specific arrangement and/or alignment and/or size distribution of polymer molecules at least in sections along the circumference of the corneal implant,
wherein after releasing the compression force the implant changes its shape from the intermediate state into an end state where the end state corresponds to the starting state, and
wherein the ring-shaped corneal implant has a modulus of elasticity of at least 1000 MPa.
