Patent ID: 7848800

Claim:
A device for ocular application of an active substance comprising a main electrode, the main electrode comprising: (i) an insulating layer, (ii) a conductive layer, (iii) an electric lead sandwiched between the insulating layer and the conductive layer, wherein the electric lead is configured for connecting the main electrode to an external electrical feeding source, (iv) an adhesive interlayer comprising material having adhesive properties for bonding the insulating layer to the conductive layer and for holding the electric lead onto the conductive layer, and (v) a foam layer bonded to the conductive layer by a conductive adhesive layer, wherein the foam layer is an absorbent foam layer able to act as a reservoir for the active substance, wherein the main electrode comprises a functional area configured to substantially cover an outer surface of an eyelid and which delivers the active substance through the eyelid onto the sclera of the eyeball and a non-functional central area.
