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.

Abstract

Devices and methods for cutting a lens in the eye are provided with a specific application being for cutting a lens while contained within the capsular bag. The device has an elongate element which forms a loop. The loop is advanced into a space between the lens and the capsular bag. The device may be used with, or incorporated into, fluid handling devices such as irrigation and aspiration devices and phacoemulsification hand pieces and disposables.

Abstract

An exemplary surgical device includes an element positionable within a shaft having a lumen defined therethrough with the element movable from a stored position to a deployed position in which a larger portion of the element extends out of the distal end of the lumen. The element forming a closed loop which is positioned around the lens while the lens is within a capsular bag. The closed loop is reduced in size to form a cut in the lens.

Abstract

A hand-held aspiration device is provided which has a relatively small suction volume along a suction path to improve responsiveness of the aspiration device when the device is activated. The device may be manually powered and may be provided without electronic controls. The device has a suction path which may be purged into a disposal enclosure to reduce the volume of material under the influence of the suction pressure during the procedure. The suction source may also be part of the hand-held unit to further reduce the suction path and suction volume.

Abstract

An exemplary surgical device includes a shaft with a lumen defined therethrough and an element movable from a stored position to a deployed position in which a larger portion of the element extends out of the distal end of the lumen; wherein motion from the stored position to the deployed position causes a first leg of the element to advance distally relative to the distal end of the shaft, and causes a second leg of the element to move proximally relative to the distal end of the shaft.
