1. An actuation system for an ophthalmic cutting tool, the actuation system comprising:
a housing comprising a chamber fluidically separated by a diaphragm into a first compartment defining a first internal volume and a second compartment defining a second internal volume, wherein the diaphragm is moveably mounted within the chamber and configured for alternate movement between a first position and a second position such that movement from the first position to the second position decreases the first volume and increases the second volume;
a first port in fluid communication with the first compartment that is configured for connection to a first conduit connected to the ophthalmic cutting tool;
a second port in fluid communication with the second compartment that is configured for connection to a second conduit connected to the ophthalmic cutting tool;
a diaphragm actuator secured to the diaphragm and configured to oscillate back and forth to move the diaphragm between the first position and the second position, and
a drive system configured to drive the oscillation of the diaphragm actuator,
wherein the ophthalmic cutting tool comprises a reciprocator assembly comprising a first sealed chamber in fluid communication with the first conduit, a second sealed chamber in fluid communication with the second conduit, and a reciprocating separator that is arranged to fluidly separate the first and second sealed chambers and is driven to oscillate by a pressure differential between the first and second sealed chambers.
