1. A pump assembly, comprising:
a rotor configured to rotate about an axis and comprising a compressing member at an outer portion of the rotor such that the compressing member is configured to rotate along a circumference;
a fluid chamber positioned at least partially around the circumference, the fluid chamber comprising:
a round outer portion comprising an inner face; and,
a membrane coupled to the round outer portion along a length of the round outer portion such that the membrane opposes the inner face of the round outer portion;
an actuator configured to cause the rotor to rotate about the axis;
a processor configured to control an output of the actuator;
a battery configured to provide electrical power to the processor and the actuator;
a wireless charging coil coupled to the processor and the battery, the wireless charging coil configured to receive wireless power to recharge the battery; and
a housing sized and shaped to be implanted in an eye cavity of a patient, wherein the rotor, fluid chamber, actuator, processor, battery, and wireless charging coil are coupled to and contained within the housing,
wherein the compressing member is configured to deform the membrane of the fluid chamber to compress the fluid chamber against the round outer portion and move a fluid through the fluid chamber.
