1. A device for performing an ophthalmic procedure in an eye, the device comprising:
a proximal portion for remaining outside the eye;
a distal, elongate member coupled to the proximal portion, the distal, elongate member comprising an open distal end and a lumen operatively coupled to a vacuum source; and
a drive mechanism operatively coupled to the elongate member and configured to oscillate the elongate member,
wherein a distal portion of the distal, elongate member is 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 lens material from the capsular bag of the eye through the open distal end and into the lumen, and
wherein the drive mechanism retracts the elongate member in a proximal direction with a retraction speed profile and advances the elongate member in a distal direction with an extension speed profile, and
further wherein the retraction speed profile comprises a maximum retraction speed of the elongate member, and the extension speed profile comprises a maximum extension speed of the elongate member that is greater than the maximum retraction speed.
