Abstract
The invention concerns an ocular iontophoresis device for delivering at least one active substance to an eyeball, comprising: a wall defining a tubular-shaped body delimitating laterally a reservoir configured for receiving the active substance(s), the wall comprising a circular distal end configured for being positioned on an ocular surface of the eyeball and surrounding the cornea and a part of the sclera of the eyeball, a first electrode configured to be positioned in front of the sclera, said first electrode being configured for delivering a first current density to the active substance(s) of the reservoir, the first electrode defining an annular-shaped first surface that is arranged in a peripheral part of the reservoir, a second electrode configured to be positioned in front of the cornea, said second electrode being configured for delivering a second current density to the active substance(s) of the reservoir, the second electrode defining a disk-shaped second surface that is arranged in a central part of the reservoir, first and second electrodes being arranged concentrically to each other, and at least one controller for independently controlling said first and second electrodes.
