Electric oculographic testing instrument

The intraocular prosthetic lens comprises an optical lens and two diametrally opposite loop-shaped support elements. Each of the support elements is made up of two mutually intersecting arches which are fastened together with the optical lens through one of their ends. The ends of the arches adjoining the optical lens are straight-line and are set at an angle of 105 to 115 degrees to each other. The ratio of the radius of curvature of the free curvilinear ends of the arches to a maximum overall length of the intraocular prosthetic lens lies within 0.16 and 0.21.

Device for processing electro-oculographic signals

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

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.
