Method and device for compacting an intraocular lens

摘要

Disclosed is an apparatus for compacting an intraocular lens. The apparatus comprises a lens compactor having a first configuration for retaining the intraocular lens in an unstressed condition and a second configuration in which the compactor stresses the lens into an at least partially compacted condition without advancing the lens along an injection axis of the compactor. The compactor accomplishes this by applying a compacting force in a direction generally orthogonal to the optical axis of the lens. The compactor is responsive to a compactor actuator that is movable by a user to change the compactor from the first configuration to the second configuration. Additional apparatus and methods are disclosed as well.

1. An apparatus for compacting an intraocular lens having an optical axis intersecting a curved surface of a viewing element of the lens and passing through a geometric center of the lens, said apparatus comprising:
a delivery lumen extending along an injection axis; and a lens compactor having a first configuration for retaining said intraocular lens in a substantially unstressed condition and a second configuration in which said compactor stresses said lens into an at least partially compacted condition by applying a compacting force in a direction generally orthogonal to the optical axis of the lens, said compactor responsive to a compactor actuator that is movable by a user to change said compactor from said first configuration to said second configuration, the lens remaining entirely outside of the delivery lumen in said second configuration, wherein said compactor comprises a compacting element which is moveable in a first direction generally parallel to said injection axis and in a second direction generally orthogonal to said injection axis.
