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 corneal implant includes a central portion and a peripheral skirt extending outwards from the central portion, and at least a portion of the peripheral skirt includes a mesh.

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.

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.

Disclosed herein is a prosthesis that may be used to replace standard prosthetic material used in osteo-odonto-keratoprosthesis (OOKP) surgery. The disclosed prosthesis is not prepared from tissue removed from a patient's tooth and jaw bone, but rather is a synthetic prosthesis. The synthetic prosthesis typically includes a solid part for supporting an optical cylinder and a porous part that facilitates bio-integration of the implanted prosthesis into the patient's eye.

A corneal implant (10) includes a central portion (12) and a peripheral skirt (14) extending outwards from the central portion (12), and at least a portion of the peripheral skirt (14) includes a mesh (16).

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.

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.

An intraocular lens includes a substantially circular lens element formed of a transparent material and one or more haptics extending outwardly from an outer edge of the lens element. The one or more haptics are formed of a polymer foam material having a negative Poisson's ratio (NPR) and are configured to couple the intraocular lens to an eye of a patient. The lens includes an inner region having a first index of refraction and an outer region disposed circumferentially surrounding the inner region, the outer region having a second index of refraction different from the first index of refraction.
