DEVICES AND METHODS FOR OCULAR SURGERY
First Claim
1. A device for performing an ophthalmic procedure in an eye, the device comprising:
- a hand-held portion;
a distal, elongate member coupled to the hand-held portion, the distal, elongate member comprising 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 in use, the device is configured to aspirate ocular material from the eye through the lumen, andwherein in use, the drive mechanism is capable of retracting the elongate member in a proximal direction with a retraction speed profile and advancing the elongate member in a distal direction with an extension speed profile, and further wherein the retraction speed profile is different from the extension speed profile.

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.
