Keratoprosthesis and method of corneal replacement
First Claim
1. To be utilized to enhance a patient'"'"'s vision, an improved keratoprosthesis comprising:
- an optical support segment, said optical support segment being structured to be disposed in assimilating engagement with an ocular musculature of on a living eyeball of the patient,an optical aperture defined in said optical support segment and structured to be disposed in aligned, relation to a cornea of the eyeball of the patient,an optical cylinder disposed in said optical aperture, andsaid optical support segment is constructed at least partially of hydroxyapatite structured and disposed to promote cell growth and vascularization therein so as to substantially increase said optical support segment'"'"'s long term assimilation with the eyeball of the patient.

Abstract
An improved keratoprosthesis, to be utilized to enhance a patient'"'"'s vision, which includes an optical support segment structured to be disposed on an eyeball of the patient and containing an optical aperture, structured to be disposed in aligned, overlying relation to a corneal region of the eyeball of the patient, defined therein. Further, the optical support segment includes a disc like configuration and is constructed of hydroxyapatite which is structured and disposed to promote cell growth, increased vascularization and/or bone formation therein so as to substantially increase the optical support segment'"'"'s long term assimilation with the eyeball of the patient, as well as its ability to combat infection and heal quickly. Disposed in the optical aperture of the optical support segment and effectively suspended in a vision enhancing position is an optical cylinder. The optical cylinder is preferably removable and provides for the transmittal of light into the eyeball.
