Abstract: An integrated apparatus includes a miniaturized flattened support having a planar surface whereon are formed wells and a microchannel, elements for projecting exciting light locally on an excitation zone of the microchannel along a direction forming an angle (?) greater than 60° with a longitudinal direction of the microchannel, optical collector elements coupled with one free end of the microchannel, optical measurement elements and processing elements, the microchannel having a portion forming a reservoir with internal cross-section flaring from its free end up to the excitation zone, the portion being extended by a conical, ellipsoidal or paraboloidal internal wall, and emerging onto a second microchannel portion with reduced internal cross-section, the latter communication with the wells.

Abstract: Intraocular lenses, for example intraocular implants, contact lenses and the like. The optical system is made of a material whereof the refractive index varies along at least one given direction, this material being a homogeneous material with variable index according to its chemical composition or by the action of mechanical effects, or a heterogeneous material with different molecular orientations. The invention is useful for making lenses with accommodative sighting.

Abstract: The invention relates to novel fluorinated organic compounds having the following molecular structure: ##STR1## where R.sub.F is a fluorinated carbon chain, R.sub.1H is hydrogen or a saturated hydrogenated carbon chain, R.sub.2H is hydrogen or a saturated hydrogenated carbon chain, R.sub.1H and R.sub.2H being not simultaneously hydrogen, the group ##STR2## comprising a principal chain and at least one linear or cyclic branch. These compounds may be prepared by reacting a phosphine with a halide under heating, and then hot reacting in a solvent the resulting phosphonium salt with a branched aldehyde or a ketone. These compounds have an excellent stability, a good biocompatibility and a high capacity to solubilize gases and particularly oxygen, such properties allowing their use in applications of the ophthalmological type or as an organ preservation medium.

Abstract: A sclerotomy implant intended to be set in place in the sclera of the eye in order to provide for a continuous flow of aqueous humor through the trabecula for the treatment of a glaucoma. This implant is configured like a platelet made of biocompatible material and comprising an intrascleral portion (1) and a sub-conjuctival portion (5), the latter being adapted to come out of the sclera and penetrate under the conjunctiva. Retaining flanges (7a, 7b) provide for the blocking of the implant in the trap under the scleral flap. The implant comprises at least one continuous flow passage from its trabecular extremity (2) applied against the trabecula up to its external extremity (6) inserted in the conjunctiva.

Abstract: The invention concerns a method and an apparatus for manufacturing a contact lens, through molding within water-tight molds. The polymerization of lenses is insured by arranging a number of molds within one or several sealed metallic chambers (9) constituting a resonant cavity of a unique mode for an ultra high frequency wave; these molds are positioned in an area of the cavity where the electromagnetic field approximately of ultra high frequency waves is homogeneous, and are distributed so that the amounts of basic composition to be polymerized act as a load fitted to the inside of said cavity.

Abstract: A process for rendering contact lenses made of a polymer or mixture of polymers hydrophilic or increasing their hydrophilic nature comprising generating a beam of positive ions which are essentially of equal kinetic energy, bombarding in an essentially uniform manner the surface of each lens by means of this beam and thereafter hydrating each contact lens; the positive ion beam is obtained by subjecting a gas from the group consisting of nitrogen, oxygen or compounds of these to an electric field produced between a cathode and an anode and in causing part of the accelerated positive ions to pass through the cathode.

Abstract: The invention relates to a fabrication method for molding a contact lens with the required optical qualities.This method consists in designing a mold (1, 2) of high thermal inertia, which is transparent to, or little absorbing the electromagnetic microwave frequencies between 10.sup.6 Hz and 10.sup.11 Hz, in developing a base composition from polymerizing double-bond monomers which are absorbing with respect to the above microwaves, and in ensuring the polymerization of the composition within the closed mold by irradiation with the above cited electromagnetic waves at a power density suited to keep the temperature at the mold level approximately below 40.degree. C.
