Ocular iontophoresis device

An ocular iontophoresis device for delivering at least one active substance to an eyeball, comprising:

• a reservoir configured for receiving the at least one active substance,
• a wall defining a tubular-shaped body arranged along a longitudinal axis, delimitating laterally the reservoir and comprising a circular distal end configured for being positioned on an ocular surface of the eyeball and surrounding a cornea and a part of a sclera of the eyeball,
• a first electrode configured to be positioned in front of the part of the sclera which is surrounded by the wall when the wall is in place on said ocular surface, said first electrode being configured for delivering a first current density to the at least one active substance of the reservoir, the ocular iontophoresis device being characterized in that it further comprises:
• a second electrode configured to be positioned in front of the cornea when the wall is in place on said ocular surface, said second electrode being configured for delivering a second current density to the at least one active substance of the reservoir,
• at least one controller for independently controlling said first electrode and said second electrode, and in that:
• the second electrode defines a disk-shaped second surface that is arranged over a central part of the reservoir, the first electrode defining an annular-shaped first surface that is arranged over a peripheral part of the reservoir,
• said first electrode and said second electrode arranged concentrically to each other, so that the first electrode and the second electrode are respectively positioned in front of part of the sclera and in front of the cornea, when the ocular iontophoresis device is positioned on said ocular surface,
• wherein the reservoir comprises a first separating wall and a second separating wall concentrically arranged to the wall defining the reservoir and defining a suction ring arranged between a first chamber provided in a peripheral part of the reservoir and receiving the first electrode and a second chamber provided in a central part of the reservoir and receiving the second electrode.
