Simulation of the Interaction of the Keratoprosthesis with the Cornea

We consider a model of a keratoprosthesis with fastening in the cornea in the form of a “skirt” (haptic), the material of which is modeled as linearly elastic. The prosthesis is placed in the cornea, the material of which is modeled as a porous, moisture-saturated medium. Using the finite element method, the stress-strain state of the keratoprosthesis elements and the cornea is calculated. Three cases of haptic fixation in the cornea and its different sizes are considered. Based on numerical analysis, the parameters of the keratoprosthesis are determined at which it is less traumatic.
