A synthetic cornea for placing in a recess formed in the cornea, the recess opening out into the anterior face of the cornea so as to leave Descemet's membrane intact. The synthetic cornea comprises a piece ( ) of flexible transparent material having an axis of circular symmetry and presenting an anterior face ( ) in the form of a spherical cap of radius Ra and a posterior face ( ) in the form of a spherical cap of radius Rp, the central zones of the two faces being separated by a distance e, and a side wall ( ) substantially in the form of a truncated cone whose axis coincides with the axis of symmetry and whose apex lies in front of the anterior face, the angle a made between the section of the side wall and the section of the posterior face in a section plane containing the axis of revolution being less than or equal to 45&deg;.

Biocompatible diphasic compositions are prepared comprising a dispersed phase suspended in a continuous phase, more particularly suitable for use as a filling material in reparative and plastic surgery. The dispersed phase consists of particles of at least one hydrogel of a (co)polymer obtained by polymerizing and cross-linking acrylic acid, methacrylic acid and/or at least one derivative of said acids. The continuous phase is an aqueous solution or hydrogel of a polymer selected from proteins, polysaccharides and their derivatives which have been cross-linked. The polysaccharide may be hyaluronic acid, its salts and a mixture of its salts, advantageously consisting of a sodium hyaluronate.

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.

Implant for deep sclerectomy

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.
