Sclero-ceratectomy implant for descemet's membrane
First Claim
1. A pre-descemetic sclero-keratectomy implant, designed for exerting a pressure on the pre-descemetic plane and on the stroma, made of crosslinked hyaluronic acid and presenting substantially the shape of a polyhedron with at least five faces wherein at least one face is structured to direct flow of the aqueous humor.

Abstract
The invention concerns a pre-descemetic sclero-keratectomy implant, designed for exerting a pressure on the pre-descemetic plane and on the stroma during a surgical treatment of glaucoma. The implant is made of crosslinked hyaluronic acid and has substantially the shape of a polyhedron with at least five faces, advantageously with five or six faces. In preferred embodiments, the implant has the shape of a prism, advantageously straight with a base shape as a triangle or parallelepiped, advantageously straight and preferably rectangular.

33. A method for reducing the intra-ocular pressure in the eye of a mammalian patient, comprising:
-
creating a space between the sclero-corneal flap and the subjacent tissues without penetration of Descemet'"'"'s membrane or endothelium, inserting in said space an implant, wherein said implant is made of crosslinked hyaluronic acid having substantially the shape of a polyhedron with at least five faces, to allow increased aqueous humour outflow from the anterior chamber of the eye, and reduce the intraocular pressure.
