Abstract: An artificial cornea comprising: an optical section having a front face and a back face and made of an optically transparent material; and a supporting section for surrounding at least a part of the optical section to support the same, characterized in that a collar section radially protruded outward from the support section is provided on the support section in its side facing the interior of an eye in the enthesis of the artificial cornea. The artificial cornea can successfully adhere to the eye tissue, prevent the outflow of aqueous humor within the eye and the invasion of bacteria into the eye, and reduce the irritation of eyelid conjunctiva. Further, it can inhibit the progress of downgrowth and causes none of a lowering in transparency of the opical section caused by the downgrowth and lifting or dropout of the artificial cornea from the buried state.
