1. A method of implanting an intraocular implant, comprising:
- (i) positioning an intraocular implant to be carried by a delivery device;
wherein the intraocular implant comprises a tube having an inlet end, an outlet end, and a tube passage;
wherein the inlet end is adapted to extend into the anterior chamber of the eye;
wherein the outlet end is adapted to be implanted adjacent scleral tissue of the eye;
wherein the implant further comprises a flange at one end of the tube, and wherein a surface of the flange is tilted at a first angle relative to a plane perpendicular to a longitudinal axis of the tube;
wherein the delivery device comprises a rodlike instrument and a retention mechanism, wherein the retention mechanism comprises an abutment surface tilted at a second angle relative to a plane perpendicular to a longitudinal axis of the rodlike instrument, wherein the second angle generally corresponds to the first angle;
(ii) forming an incision in the eye;
(iii) directing the implant to a desired implantation location; and
(iv) withdrawing the delivery device.
