1. A method, comprising:
advancing a distal end portion of a puncture member of a medical injector through a sclera of an eye until the distal end portion of the puncture member reaches a suprachoroidal space (SCS), the puncture member defining a lumen having a longitudinal axis;
moving a flexible cannula distally relative to the puncture member such that an atraumatic distal end of the flexible cannula exits the lumen along the longitudinal axis, and beyond the distal end portion of the puncture member along the SCS, thereby expanding the SCS; and
administering a drug formulation to the expanded SCS.
