Device for ophthalmologic operations

Posterior-chamber intraocular prosthetic lens

An optical prosthetic device made from a material based on silicone compounds is a cured composition resulting from vulcanization of a mixture of .alpha.,.omega.-bis-trivinylsiloxyoligodimethyl(methylphenyl)-siloxane and .alpha.,.omega.-bis-trimethyl(dimethylhydro)siloxyoligomethyl(phenyl)methy lhydro-siloxane in the presence of a polyaddition reaction catalyst based on the compounds of metals of the platinum group, the ratio of the first mixture component to the second one ranging within 100:1 and 100:20 parts by mass.

Material for ocular prosthetics

An optical lens is secured to supporting setting platforms, of which one is formed by a circumferential sector conjugated with the optical element (lens) so as to form shoulders. The other of said platforms is formed by two rounded-off radial portions conjugated with each other and with the optical element. Both of the platforms have biconcave surfaces, and one of these is thicker than the other.

A method for automatic processing of electro-oculographic signals consists in carrying out visual stimulation of a patient at a preset stimulation angle and within a preset period of time, recording the signal of the bioelectric potention of the patient's eye, amplifying said bioelectric potential signal and limiting its spectrum, measuring the amplitude of the bioelectric potential signal at preselected instants of time, and subjecting the thus-measured values of the amplitude of said signals to statistical analysis to determine a constant electro-oculographic eye potential. The time instants at which the amplitude is measured are selected by determining the global extreme values of an absolute magnitude of the bioelectric potential within a preset number of stimulation cycles, comparing the modules of the thus-fixed global extreme values to one another and comparing the time intervals between the fixed global extreme values with the stimulation period.

The invention generally relates to medicine, but more particularly, to an strument for making corneal incisions useful, for example, in the surgical treatment of myopia. The instrument disclosed herein includes a case, a holder of a cutting member being mounted within the case for reciprocation relative thereto. The holder is provided with a lock member for a cutting member at one end thereof, its opposite end accommodating a stem engaging a screwnut type drive urging said holder into motion. A stop is mounted on the case anteriorly relative to said holder. According to the invention, the portion of the holder facing the stop which is rectangular in cross-section, is preferably provided with a rectangularly fashioned groove along with a lever clip mounted therein, to secure the cutting member in position.

Instrument for making corneal incisions

The invention relates to ophthalmology and, more particularly, to a corneal ncision marker adapted for use in surgical treatment, notably that of myopia. An instrument of this invention comprises a case in the form of a bush accommodating a sight, and plates in planar arrangement at right angles to the plane of the sight. The plates are brought into contact with the cornea leaving indentations which serve as guidelines to perform incisions. According to the invention, each plate is mounted on a separate holder, the latter being attached movably radially with respect to the bush, the holders being rigidly secured in their entirety to said bush, and provision is made for a drive to effect smooth synchronized movement of the plate holders.
