Abstract
Two elongated side plates are pivotally connected together for rotation about an axis extending lengthwise of and between the side plates. Thin, elongated necks extend distally from the side plates to a pair of jaws configured to grasp and release a foldable intraocular lens. The necks connecting the jaws to the side plates are shaped such that adjacent points are substantially intersected by the axis, with such intersection point located to be positioned at approximately the corneal incision during a lens implantation procedure. Thus, with the jaws positioned interiorly of the lens capsule, the jaws can be swung between open and closed positions without unnecessary stretching of the corneal incision.
