Abstract
A tip formation for an instrument for inserting a flexible membrane into an eye is formed at the distal end of a cannula. The cannula has a lumen which directs the flexible membrane through an incision and into the eye. The distal end is beveled so as to provide ease of entry into the incision and to orient the discharge opening for the flexible membrane at an inclination to the longitudinal axis of the lumen. The cannula walls about the beveled end are tapered to form a smaller sized end without impeding the advance of the membrane.
