RU No. 2254883, CL A61N 1/30, A61H 35/02, publ. 06/27/2005).

The disadvantage of this bath is the design complexity due to the execution in the form of an oval with wide and narrow ends, close to the shape of the orbit, while the narrow end is raised above the wide end by 5-8 mm at an angle of 25-30 degrees to the end plane of the bath, which is not always corresponds to the shape of the eye, and also that it does not exclude accidental movements of the eyeball, which leads to disruption of the electrode contact with the pathological focus and leads to a destructive effect on healthy tissues, and there is no regulation of drug supply substance in the eye tissue.

The closest in technical essence and the achieved positive effect and adopted by the author for the prototype is a device for electrophoresis of a medicinal substance in the eye tissue, containing a bath with an electrode, while the bath is made in the form of a plastic cylinder and equipped with a piston with a gasket in which the electrode is mounted and which is made with the possibility of vertical and rotational movement, while the diameter of the cylindrical bath is 30-36 mm, and the base is made with oval side stops (see . The PM №18822, Cl. A61F 9/00, publ. 20.07.2001 city).

The disadvantage of this device is the loose fit of the end surface of the device to the edges of the orbit of the eye, which creates the leakage of the drug substance.
