Abstract: An ophthalmic surgical instrument includes an instrument hand grip portion having an elongated configuration with proximal and distal ends, and a tip portion extending from the distal end. The hand grip portion includes a reservoir for containing an irrigation fluid and a button to selectively provide an irrigation fluid (i) through the instrument, or (ii) around the instrument when coupled with an irrigation sleeve arranged around the instrument. The tip portion has the form of an elastomeric element having a base secured to the distal end of the hand grip portion and a free end extending from the base. The free end is configured for massaging the trabecular meshwork and outer wall of the canal of Schlemm in the eye to improve aqueous outflow for the reduction of intraocular pressure.

Abstract: An electrode for use in electric prevention for corrosion, the electrode comprising a sintered body of a mixture of iron oxide of 90 to 55 mol % in terms of Fe.sub.2 O.sub.3 and a metal oxide of 10 to 45 mol % in terms of MO (M is at least one metal selected from the group consisting of Mn, Ni, Co, Cu and Zn), and a process of electric prevention for corrosion by using said electrode as an anode.
