The present invention provides a keratoprosthesis assembly comprising a central optical core; and a peripheral skirt comprising at least one porous biocompatible layer and methods of using it in keratoprosthesis procedures.

Corneal transplant procedures may involve suturing an implant of healthy corneal tissue to a recipient cornea. The sutures may cause unwanted deformation of the corneal implant and the recipient cornea. A supporting structure may be embedded into the corneal implant to enhance the stability of the corneal implant and the recipient cornea and to reduce the likelihood of unwanted deformation when the corneal implant is sutured to the recipient cornea. According to one embodiment, a corneal implant includes donor corneal tissue extracted from a donor cornea. The donor corneal tissue includes an interior channel formed at a depth below an anterior surface. The corneal implant includes a supporting structure formed from non-tissue material and positioned in the channel.

Artificial corneas suitable for surgical implantation are provided. Embodiments of artificial corneas include an optical an optical element that includes a body having an anterior side and a posterior side, an annular flange extending about the body, the anterior side including an anterior optical surface and the posterior side of the body including a posterior optical surface, and a tissue integration skirt coupled to the optical element, the tissue integration skirt being configured to promote tissue ingrowth, the tissue integration skirt being coupled to the optical element such that at least a portion of a periphery of the annular flange defined between the anterior and posterior sides of the optical element is covered by the tissue integration skirt. Also described are methods for implanting an artificial cornea of the present disclosure, the methods including providing the artificial cornea, removing a section of corneal tissue from the patient's cornea to form a tissue bed of existing tissue to which the artificial cornea can be affixed, implanting the art the artificial cornea such that the posterior side of the artificial cornea is suspended above the interior of the eye, and mechanically affixing the implanted artificial cornea to the existing corneal tissue of the tissue bed.

The present disclosure relates to keratoprosthesis apparatuses and methods of manufacturing keratoprosthesis apparatuses. The keratoprosthesis apparatus includes a circular backplate including a central aperture extending through the backplate from a face of the backplate to a posterior surface of the backplate. The circular backplate has a dome shape and comprises a plurality of spaced apart elongated slits extending radially outwardly from a central portion of the backplate. The plurality of spaced apart elongated slits surround the central aperture and extending through the backplate from the face of the backplate to the posterior of the backplate.

A tear shaping structure or structures that shape a tear film of an eye thereby enabling a desired refractive effect. The tear shaping structure includes a supporting structure supporting a plurality of capillary action members, the capillary action members being spaced apart and arranged in such a way as to create a desired refractive lens effect by shaping the tear film of an eye.

The present invention provides a keratoprosthesis assembly comprising a central optical core; and a peripheral skirt comprising at least one porous biocompatible layer and methods of using it in keratoprosthesis procedures.

Reversibly deformable corneal implants for replacing excised corneal tissue, the implants including an optical portion and an anchoring portion having different mechanical properties from each other.

A method of intracorneal lens implantation with a cross-linked cornea is disclosed herein. The method includes forming a pocket in a cornea of an eye, applying a photosensitizer inside the pocket so that the photosensitizer permeates at least a portion of the tissue bounding the pocket, the photosensitizer facilitating cross-linking of the tissue bounding the pocket; irradiating the cornea so as to activate cross-linkers in the portion of the tissue bounding the pocket, and thereby kill cells therein; inserting a lens implant into the pocket; and applying laser energy to the lens implant in the pocket using a laser so as to correct refractive errors of the lens implant and/or the eye in a non-invasive manner. In other embodiments, a lens implant is soaked in a cross-linking solution that includes a photosensitizer prior to being inserted into the pocket in the cornea of an eye.
