Abstract:
An artificial cornea comprising(1) an optical element which is made of an optically transparent material, and a planar shape of which is circular, having a front surface, a posterior surface and a side face; (2) a skirt having a microporous structure into which corneal tissue grows, and a planar shape of which is concentrically annular, surrounding a part of the side face or the whole side face of said optical element; and (3) a flange radially and annularly protruding outwardly from the side face of said optical element so that a front surface of said flange contacts with a posterior surface of said skirt; wherein the average pore size of micropores in said skirt is 10 to 100 &mgr;m, and the micropores are open cells; wherein thickness of said skirt is the same as that of an incisional wound surface of a cornea so that a side face of said skirt is configured to contact with the whole incisional wound surface; wherein said flange protrudes outwardly to radius direction from said skirt by 0.5 to 2 mm; and wherein parts of said flange protruding from an end of the side face of said skirt are configured to contact with the inside of the cornea during implantation of the artificial cornea into the corneal tissue so that the artificial cornea is not excluded from the ocular tissue.
