Abstract: Provided is an ophthalmic surgery instrument that allows an instrument suitable for excising a trabecular meshwork to be configured and allows a grip portion to be used for both first ophthalmic surgery such as trabeculectomy and second ophthalmic surgery. A first passage and a second passage for performing suction or supply of a perfusate are formed in a grip portion of an ophthalmic surgery instrument. An internal thread portion is formed at a tip end of the grip portion. A tip end member for first ophthalmic surgery has a single passage therein, and has a bent-shaped blade portion and an opening of the passage at a tip end thereof. The tip end member for first ophthalmic surgery and a tip end member for second ophthalmic surgery are selectively screwable to the internal thread portion.
