Keratoprosthesis, and system and method of corneal repair using same
First Claim
1. A keratoprosthesis comprising:
- an optic member disposable in vision facilitating relation to an eye of a patient;
a biocompatible support having a channel disposed through said support, the channel defining a collar extending away from an anterior side of said biocompatible support;
said optic member disposed in said channel of said support such that the collar is disposed in at least partially surrounding relation to the optic member, said biocompatible support structured to be secured in place at a position anterior to a cornea of a patient'"'"'s eye and to engage soft tissue;
at least a portion of a surface of said biocompatible support including a treated surface structured to promote adhesion of soft tissue thereto, wherein said biocompatible support comprises a metallic material; and
wherein said collar and said biocompatible support comprise the same metallic material.

Abstract
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.
