Abstract
The invention concerns an implant for deep sclerectomy for draining aqueous humor during 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 the shape of a polyhedron with five or six faces. In a preferred embodiment, the implant has substantially the shape of a prism, advantageously straight with a trapezoidal base.
Claims27
An implant for deep sclerectomy, intended to drain the aqueous humor, 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.
A method for treating glaucoma according to the surgical technique of deep sclerectomy carried out with an implant, said method comprising
- incising the sclera until plumb with Schlemm's canal to generate a cavity in the deep scleral bed,
- inserting in said cavity an implant, wherein said implant is made of crosslinked hyaluronic acid and presents substantially the shape of a polyhedron with at least five faces.
A deep sclerectomy implant made of crosslinked hyaluronic acid having substantially the pre-formed shape of a polyhedron with at least five faces and a thickness of about 2 mm, wherein at least one face is structured to direct flow of the aqueous humor.
A method for reducing the intra-ocular pressure in the eye of a mammalian patient, comprising:
- incising the sclera of an eye until plumb with Schlemm's canal to generate a cavity in the deep scleral bed, and
- inserting an implant in said cavity, 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 humor outflow from the anterior chamber of the eye, and reduce the intraocular pressure.
