Abstract. A microsurgical instrument for performing selective trabeculectomy in surgical treatment of glaucoma includes flexible probe means (A) and a cutting member (C) fixed to the same, The cutting member comprises two knife blades (C1,C2) protruding in different directions from the probe means and each providing at least one sharp edge (E1,E2) turned towards a free end of the probe means. The instrument is designed to be pulled between two incisions in the eye wall with the probe means foremost through the Canal of Schlemm at the transition between cornea and sclera, thereby cutting away the inner wall of the canal and the corresponding part of the trabecular mesh- work located in the canal. The aqueous humour of the eye then gains access to the outer wall of the Canal of Schlemm with its drainage outlets leading out of the eye.
