1. A method for treating a condition of an eye comprising:
advancing a distal end of a cannula of a fluid delivery system into an eye, the fluid delivery system comprising a reservoir, a linear gear, and a linkage coupling the reservoir and the linear gear;
moving the linear gear relative to the linkage in a first direction with the fluid delivery system in a first configuration to deliver a fluid composition contained within the reservoir to the eye, wherein in the first configuration a first set of teeth on the linear gear prevents movement of the linear gear relative to the linkage in a second, opposite direction; and
transitioning the fluid delivery system from the first configuration to a second configuration in which a second set of teeth on the linear gear allows movement of the linear gear relative to the linkage in the first direction and second, opposite direction.

18. A method for treating a condition of an eye comprising:
advancing a distal end of a cannula of a fluid delivery system into an eye, the fluid delivery system comprising a reservoir, a linear gear, and a linkage coupling the reservoir and the linear gear;
moving the linear gear relative to the linkage in a first direction, wherein movement of the linear gear in the first direction causes a distal portion of the linkage to flex in a first plane; and
moving the linear gear relative to the linkage in a second, opposite direction, wherein movement of the linear gear in the second opposite direction causes the distal portion of the linkage to flex in a second, different plane.
