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
Abstract: Device for sampling tear fluid that comprises: an extraction element (202) adapted to be applied on the eye to draw tear fluid therefrom, comprising at least one tube (209) and a distal portion (201) with at least one opening (207), a collection vessel (203), connected to said tube (209), suction means (210) adapted to continuously draw tear fluid from the eye to the collection vessel (203), through the extraction element (202) for a period higher than 10 minutes once the extraction element (202) is in place.
