ABSTRACT:
Apparatus for introducing an ionized drug solution into the eye having a member formed of an insulating material adapted to be secured to the eye. The member has a nose which is adapted to come in contact with the eye and form a liquid-tight seal therewith. The member has a passageway therein with a cross sectional area of less than approximately 1 millimeter in diameter. An ionized drug solution fills the passageway. An electrical circuit is provided for causing current flow through the drug solution to cause a high voltage gradient and a high current density to be established in the eye in the vicinity of the portion of the eye in contact with the drug solution in the passageway to cause the drug solution to be carried from the passageway into the eye.
