Abstract
A device for restoration of visual functions in cases of affected optic nerve and retina comprises an electromagnetic field radiator emitting the latter field into the region of the eyeball and an electromagnetic field receiver adapted to interact with the radiator, both of them exerting an electrostimulation effect on the optic nerve and the retina. The electromagnetic field radiator is essentially a source of a pulsed magnetic field and is shaped as an electromagnet provided with an adjuster of a distance between the end of the electromagnet and the electromagnetic field receiver, which is in effect an inductor having lead wires furnished with electrodes whose active surface exceeds 10 mm.sup.2. A method for restoration of visual functions in cases of affected optic nerve and retina consists in conducting electrostimulation of the eyeball, for which purpose an inductor is implanted into the orbit on the sclera of the posterior portion of the eyeball in such a manner that one of the inductor electrodes is positioned nearby the external tunic of the optic nerve, while the other electrode is fixed on the sclera in the area of the eyeball equator, whereupon a pulsed magnetic flux is applied remotely to the eyeball portion carrying the inductor, the magnetic field induction being from 0.1 T to 0.25 T, while the pulsed magnetic field is simultaneously brought in synchronism with pulsation of the internal carotid artery.
