An accommodative intracapsular implant comprises a central optical part and at least two haptic arms (), the free ends () of which are embodied to cooperate with parts of the equatorial zone of the capsular bag, wherein the optical part is formed by joining two elastically-deformable bodies, one body being formed as an envelope () and the other body being formed as a core ().

Intracapsular accomodative implants

An accommodating intraocular implant for locating in the capsular bag, the implant comprising a single piece of elastically deformable material constituting a central lens ( ) and at least two haptic portions ( ) in the form of radial arms for bearing via their free ends against the equatorial zone of the capsular bag, the free end of each radial arm ( ) being fitted with a shoe ( ) of substantially toroidal outside surface enabling the implant to bear against the equatorial zone of the bag, the connection between each shoe ( ) and the corresponding arm ( ) being of the hinge type situated in the vicinity of the posterior edge of the shoe ( ) and being formed by a first thin portion ( ) of the arm, while the connection between each arm and the lens is of the hinge type implemented at the anterior surface of the lens by a second likewise thin portion ( ) of the arm, the plane (P ) containing the first thin portions being situated behind the plane (P ) containing the second thin portions.

Keratotome for performing arcuate incisions

The invention concerns a device for correcting the shape of an object by laser treatment. The device comprises means (1) for emitting a laser beam (FL) and means (2) for generating a treatment laser beam (FLT) comprising at least one lobe of elongate cross-section. Means (3) enable focussing of the image of the lobe or lobes of the treatment laser beam on the area of the object (OE) to be corrected and means (4) enable displacement of the image of the lobe of the treatment laser beam in translation or in rotation over the area of the object to be corrected. The total correction or ablation is effected by the summation of a plurality of elementary discrete ablations. Application to refractive surgery in the case of keratomileusis for myopia, hypermetropia or astigmatism, and to shaping contact lenses and intra-ocular implants.

The instrument comprises a tubular outer support forming a shell around a determined axis and including a circularly symmetrical annular base portion about the axis defining a substantially spherical annular surface enabling the support to be pressed against the cornea; the support includes a cylindrical inside wall that is resiliently deformable in the radial direction to receive the tubular top section of a template having a transverse wall at its bottom which is delimited by a substantially spherical bottom surface and which includes a central orifice and at least one pair of arcuate slots disposed symmetrically about the center of the wall.

Instrument for surgery of the cornea

A lense for keratometry and a keratotome for making an incision for receiving such a lense. The lense comprises an optical zone and an anchoring zone with a sloping shape such that this zone can be inserted under a strip disengaged from the cornea of the receiving eyeball via a tapering incision diverging from the cornea. The keratotome according to the invention is adapted to perform such an incision. The result is that the lense is anchored in the cornea in a more efficient, less traumatic and more aesthetic manner.

Surgical apparatus for radial keratotomy

An intra-ocular implant constituted by a lens provided with loops for fixation extending substantially radially outside the lens. According to one of the features of the invention, at least one of the front loops is constituted by two wires curved towards each other and terminated by sharp points which overlap in rest position.

Intra-ocular implant

The present invention concerns a trephine for making at least one circular incision on the cornea of an eye. The trephine comprises an external support forming a casing and having a base portion for applying it to the eye, an internal blade carrier which is movable in the support, and a drive mechanism for driving the blade carrier with respect to the support. The blade carrier is driven by the drive mechanism which causes it to screw into and out of the support and the blade is cylindrical, the cutting blade portion being formed by its lower circular edge.
