This instrument is a kind of synthesizing electric chemistry and medical instrument. It puts medicines that need to lead into the organization in the same magnetic field and use the principle of repulsion of the same nature to make the medicine ion directly lead into the organization without passing the blood circulation, and let the medicine give full play on its effect when it can keep higher concentration and longer time inside the organization. This instrument uses low and direct voltage and steady constant flow source to make the positive ion of the medicine be conducted by positive electrode and negative ion be conducted by negative electrode after ionization. It is superior to the part medicine and suitable for different eye diseases.
