An instrument for the insertion of an intraocular lens into an eye comprises a body portion (10), a nose portion (14) through which runs a passage for the lens to pass to a dispensing tip, and a plunger (12). The nose portion (14) is pivotally connected to the body portion (10) 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.

Why it's free to use
- Filed December 29, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 29, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 29, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
