A device for extracting lens material from an eye including a distal, disposable portion releaseably coupleable to a proximal, reusable portion. The disposable portion includes a cutting tube having a distal cutting tip and an inner lumen having a distal end. The disposable portion includes an aspiration pump fluidly coupled to the inner lumen of the cutting tube and a cutting tube drive mechanism configured to oscillate the cutting tube. The reusable portion includes an aspiration pump motor configured to drive the aspiration pump and a coupler for releaseably operatively coupling the pump motor to the aspiration pump. Related devices, systems, and methods are disclosed.

Ophthalmic cutting instruments having integrated aspiration pump

A device for performing an ophthalmic procedure in an eye including a hand-held portion; an elongate member extending from a distal end region of the hand-held portion; and an aspiration pump within the hand-held portion. The elongate member includes a lumen and an opening near a distal end region of the elongate member. The aspiration pump is in fluid communication with the opening of the elongate member. The aspiration pump includes a camshaft extending along a longitudinal axis and having a plurality of lobed cams; tubing extending parallel to the longitudinal axis; and a plurality of cam followers driven by the cams of the camshaft to move in a plane perpendicular to the longitudinal axis to sequentially compress the tubing. Related devices, systems, methods are provided.
