Abstract
An artificial cornea capable of preventing a separation thereof from an eyeball of the patient during an implant operation thereof while avoiding post-operative complications at the interface between the artificial cornea and the patient's cornea, such as erosive tissue necrosis (melting), leakage of aqueous humor, infection, extrusion of the implant, and intraocular inflammation. The artificial cornea includes an artificial cornea body having, at a lower portion thereof, a cylindrical portion adapted to be arranged in the interior of a patient's eyeball, and, at an upper portion thereof, an optical portion adapted to be exposed through an anterior portion of the patient's eyeball, the optical portion having a diameter less than that of the cylindrical portion to define a step at a lower end thereof, a skirt fitted around the optical portion of the cornea body and seated on the step, an anterior flange coupled to an upper surface of the skirt, and a support member attached to a lower end of the cylindrical portion and adapted to support the artificial cornea body. An amnion is covered on the implant in order to promote a stable graft of the artificial cornea to the patient's cornea during an initial reaction period for the recovery of a cut portion of the patient's cornea.
