A needle instrument for performing peripheral iridectomy for narrow angle glaucoma includes a hollow needle having a first right angle bend and a second U-shaped bend. An adaptor and conduit are provided for connecting the needle to a source of suction such that suction may be drawn through the open end of the needle. The needle is adapted to be grasped by a hemostat or the like along the U-shaped bend to facilitate manual manipulation during performance of a peripheral iridectomy.
