Abstract
A finite-element simulation for the implantation of corneal rings for patients with high myopia is presented. The eyeball is modelled by joined spherical segments with different geometries and elastic properties. The ring implantation process is modelled by three surface-surface contact pairs: contact between corneal layers and contacts of the ring and with the lower and upper surface of the corneal pocket. The role of the surgical parameters (the MyoRing thickness and the implantation depth) on the stress-strain state is studied. The results of the simulation were compared with the clinical data on the change in curvature after the surgery.
