PCT No. PCT/FR94/01311 Sec. 371 Date Nov. 15, 1995 Sec. 102(e) Date Nov. 15, 1995 PCT Filed Nov. 9, 1994 PCT Pub. No. WO95/13036 PCT Pub. Date May 18, 1995The invention relates to a surgical instrument of the punch forceps type, designed to perform trabeculectomy, the instrument including an elongate body (101) on which an elongate lever (102) is hinged, and a punch (110) constituted by a tubular blade (120) and a cutting plunger (130). According to the invention, the tubular blade (120) of the punch (110) is mounted to be forwardly inclined so as to define an obtuse angle (a) with the body (101) lying essentially in the range 95 DEG to 160 DEG , and the notch in the cutting plunger (130) of the punch (110) has a cutting edge (134) which is raised so as to be capable of engaging the tissue to be cut when said plunger is withdrawn. The punch (110) is preferably mounted so as to be interchangeable, thereby making it possible to have a cutting plunger that is interchangeable or suitable for single use.
