Abstract
An instrument for the insertion of an intraocular lens into an eye comprises a body portion, a nose portion through which runs a passage for the lens to pass to a dispensing tip, and a plunger. The nose portion is pivotally connected to the body portion so that the barrel can be broken open for the placement of the lens into the nose portion. The lens is preferably placed on two spaced parallel nose pins to facilitate its folding. A cross pin preferably straddles the nose pins and under which the lens is arranged to pass, to prevent lifting and tilting of the lens.
