Abstract
A through corneal prosthesis is proposed which comprises a bearing member to be introduced between the corneal layers and a bushing with a threaded hole rigidly mounted on the bearing member, the threaded hole threadedly receiving a removable optical cylinder. For the period of implantation of the bearing member, instead of the optical cylinder a temporary removable plug is screwed in the bushing, the height of the bushing and the plug not exceeding the thickness of the cornea, so that the bearing member of the prosthesis is implanted without requiring perforation of the corneal layers.
