A dual-pump system features the ability to switch from a flow-based peristaltic pump to a vacuum-based venturi pump instantaneously in the same case during different steps of the phaco procedure. With this type of system, surgeons can instantly change pumps using a single machine, allowing them to customize their settings depending on which pump they prefer for each phase of surgery. Typically, surgeons prefer the peristaltic pump for nuclear disassembly (chopping, cracking) and the venturi pump for quadrant removal and irrigation and aspiration (I&A).
