Abstract:
Devices, systems, and methods for performing an ophthalmic procedure in an eye are disclosed. The devices include a hand-held portion and a distal, elongate member coupled to the hand-held portion having a lumen operatively coupled to a vacuum source. A drive mechanism operatively coupled to the elongate member is configured to oscillate the elongate member. When in use, the device is configured to aspirate ocular material from the eye through the lumen. The drive mechanism retracts the elongate member with a retraction speed profile and advances the elongate member with an extension speed profile. The retraction speed profile is different from the extension speed profile.

Claim (Index 1):
A device for extracting lens material from an eye, the device comprising:\n a hand-held portion comprising a proximal, reusable portion releasably coupleable to a distal, disposable portion; said proximal, reusable portion comprising:\n a motor; and \n a rotatable coupler for releasably operatively coupling the motor to the distal, disposable portion, \n said proximal, reusable portion configured to remain outside of the eye; \n said distal, disposable portion comprising:\n an elongate member comprising a distal cutting tip and an inner lumen having an open distal end, said elongate member sized and configured to extend through an anterior chamber of the eye and to a capsular bag of the eye, and further wherein in use, the device is configured to aspirate the lens material from the capsular bag of the eye into the inner lumen; \n an irrigation lumen coupleable to a source of irrigation fluid; \n a plurality of pistons, each of said plurality of pistons housed within a cylinder, each of said cylinders operatively coupled to said inner lumen; and \n a rotational cam assembly capable of being rotated by the motor via said rotatable coupler, wherein rotation of said rotational cam assembly causes said plurality of pistons to generate pulses of discontinuous negative pressure within the inner lumen.
