摘要
A keratoprosthesis and system and method of using same for corneal repair. The keratoprosthesis comprises a biocompatible support and an optic member disposed through a channel within the support. The support includes metal, preferably titanium, and treated, such as by sandblasting and/or acid etching, to create textured surfaces that promote soft tissue adhesion. A locking member interconnects the optic member and support. An outer surface of the locking member a collar extending from the support and disposed around the optic member is also metal, preferably titanium, and is similarly treated to promote soft tissue adhesion. A locking member interconnects the optic member and support. The system includes the keratoprosthesis positioned within an isolated soft tissue segment of a non-ocular tissue, such as buccal mucosa, placed on the anterior cornea. The method includes removing corneal epithelium, isolating and transplanting a segment of soft tissue to the de-epithelialized cornea, creating a receiving area in the soft tissue, positioning a keratoprosthesis relative to the receiving area anterior to the cornea, and securing the keratoprosthesis.
