The elongate body has a forward end and an insertion head that extends from the forward end. The insertion head defines a shearing edge suitable for cutting eye tissue engage thereby. The forward end and the insertion head of the body define a shoulder surface. The conduit has a first end defined on a portion of a top surface of the insertion head. The conduit also extends through the body from the forward end to a back end thereof. The first end of the conduit is spaced from the shearing edge and, in one example, from the shoulder of the body.
