An iontophoretic apparatus for ocular iontophoresis comprising a housing element formed to cooperate with the eye. In cooperation with the housing element is a flexible current distribution element that is capable of transmitting electrical current. Coupled to the current distribution element is a conformable medicament containment element that is filled with a medicament which is released under the influence of an electrical current, while a barrier element is provided that is configured to reduce current flow outside of the barrier and aid in the preferential delivery of medicament.
