Claim 0:
1. An intraocular lens exchanger for moving a foldable intraocular lens (IOL), the intraocular lens exchanger comprising:
an outer tube having a first passage formed in a forward/rearward direction;
an inner tube disposed to be movable along the first passage and having a second passage formed in the forward/rearward direction; and
a variable tube extending from a front end of the inner tube to form a variable passage connected to the second passage,
wherein the variable tube has an extension part having a width that increases forward in an unconstrained state in which the variable tube is not positioned in the first passage, and the extension part is provided to be elastically deformed when the unconstrained state changes to a constrained state in which at least a part of the extension part is received in the first passage, and
wherein the extension part includes a plurality pleated portions formed curvedly in a circumferential direction so as to be relatively extended in the circumferential direction while being unpleated in the unconstrained state in comparison with the constrained state, or to be relatively contracted in the circumferential direction while being pleated in the constrained state in comparison with the unconstrained state.
