Abstract: A novel ophthalmic viscosurgical system and method is disclosed. The system and method comprise multiple viscoelastic solutions that are pre-selected based on desired characteristics. Each solution is placed in distinct locations within the eye during surgery to maintain the natural shape of the eye and facilitate the surgical procedure. Novel viscoelastic solutions for use in association with the present invention are also disclosed.

Abstract: The invention concerns a device for treating presbyopia or other ocular disorders related to any eye accommodation defect. The device (20) includes a piece (22) shaped as a ring portion with an axis of revolution and first (22a) and second (22b) edges offset along radial directions and along the direction of said axis of revolution. The first edge (22a) is disposed to rest, over at least part of its length, on part of the eye internal wall and the second part (22b) is capable of being pressed against a median zone (18c) of zonules of the crystalline lens (18). In this way a displacement of the median zone of said zonules is obtained. This displacement enables them to cause the deformation of the crystalline lens (14) under the effects of stimulation applied to the zonules.

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.

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.

Abstract: The invention relates to a device for measuring the pressure of a liquid flowing in a tube (20, 22) into or out from the human body, the device comprising: an elongate body (10) having first and second ends (12, 14), an axial bore (16) opening out into said ends and defined by an inside wall (16a), and a recess (18) opening out into said axial bore between its two ends, each end of said body having means (12a, 14a) for connection to said tube (20, 22); and a pressure sensor (30) having a portion mounted in sealed manner in said recess (18), the surface of said sensor which is subjected to the pressure of said liquid being of a shape that is flush with the inside wall of said axial bore at said recess.

Abstract: A posterior-chamber intraocular implant for correcting short-sightedness in a phakic eye. Comprises a substantially circular optical portion (30) consisting of a front dioptric surface (40) and a rear dioptric surface (42) and a haptic portion. The haptic portion includes two extensions (32, 34) joined to the edge of the optical portion, of which the ends are spaced apart by a distance greater than the diameter of a dilated pupil, and two portions (52, 54) for attachment, the front surface of each extension comprising a toroidal portion (44) joined to the front dioptric surface, the rear surface of each extension comprising a toroidal portion (46) forming portion engaging the lens circumference and connected to the rear dioptric surface and a connecting portion (48), the rear dioptric surface and the toroidal portions of the rear surfaces of said extensions defining a recess (50) for freely altering the curvature of the front lens surface.

Abstract: The invention relates to a corneal prosthesis device for putting into place in the cornea. The device comprises an optical part (10) made of a first transparent material and of substantially cylindrical shape presenting an anterior face (14) defining an optical surface and a posterior end (16), an annular anterior skirt (18) projecting from the side wall of the optical part and being made of a biocompatible and biocolonizable synthetic polymer that is distinct from said first material, and a posterior annular skirt (20) projects from the side wall of the optical part and is made of said first material.

Abstract: The invention relates to an intraocular implant made of a flexible material presenting an optical refractive index included between 1.40 and 1.56 including an optic portion (10) and a haptic portion, the optic portion generally being circular. The optic portion of the implant has a cylindrical circumferential surface (16) with a width e of 0.1-0.3 mm and a diameter De of 5-7 mm, and two main surfaces (12, 14), each consisting of a spherical cap (18) of which the geometrical axis coincides with the optical axis and a frusto-conical surface (20) with an inner edge connected to the edge of the spherical cap via a toroidal surface portion (22), and an outer edge connected to said circumferential surface, the thickness E of said optic portion being between 1 and 1.5 mm along the optical axis.

Abstract: The invention relates to a method of making an intraocular implant having a flexible lens. The method includes in using a mold having two parts (12) and (16) which are disposed on either side of a plate (20), e.g. made of PMMA, which plate includes a central orifice. The material (32) that is to constitute the lens portion is disposed in the central cavity of the mold. This material may be an acrylic, for example. After unmolding, the plate (20) is machined to make the haptic, and optionally the part (32) is machined to make the lens.
