An ophthalmic probe (11) for use in sub-tenon blocking has an elongate injection-moulded plastics stem (12) with an angled pointed conical tip (13) at one end for piercing and manipulation of the conjunctiva to admit entry of a cannula administrating liquid anaesthetic. Finger-hold pairs (14,15) at intermediate locations along the stem (12) enable controlled manipulation of the probe (11) during surgery, and an optional dissector (16) with blunt tip and edge (17) at the other end of the stem (12) may be used without cutting, in opening a pocket for the anaesthetic.
