Abstract: The present invention discloses bioengineered corneal grafts for treating either or both Keratoconus and visual impairment, selected from (i) a corneal Onlay comprises or coated by at least one member of Group A, consisting of biocompatible synthetic materials; at least one member of Group B, consisting of at least one type of biological polymer and optionally, at least one member of Group C, consisting of at least one type of protein and (ii) An intrastromal corneal lenticule graft, configured to mimic native corneal stroma tissue by means of its optical properties, mechanical properties, permeability and interaction with corneal stromal cells; wherein at least one portion of said lenticule comprises or coated by at least one member of Group D, consisting of transparent crosslinked hydrogel; at least one member of Group E, consisting of collagen; collagen methacrylate, recombinant mammal collagen, mammal-sourced collagen; and optionally, at least one member of Group F, consisting of Keratocytes and/or stem c

Abstract: A method of manufacturing a retinal graft. The method includes: (a) preparing a scaffold material solution; (b) air-drying the scaffold material solution, to form a thin scaffold layer; (c) crosslinking the thin scaffold layer; (d) rehydrating the scaffold layer; and (e) applying retinal pigment epithelium cells onto the scaffold layer.
