ABSTRACT:
A multi-part intraocular lens that can be surgically implanted within an eye through an incision having a length substantially less than the lens' diameter. The lens includes a plurality of lens segments that are slidable between a retracted orientation, in which they cooperate to form a generally circular lens, and an extended orientation, in which they cooperate to form an elongated assembly having a transverse width substantially less than the lens' diameter. To surgically implant the lens, it is inserted through the eye incision in the extended orientation, whereupon further insertion causes the lens segments to slide to their retracted orientation automatically, without the need for a risky assembly of segments using surgical instruments within the eye.
