Abstract
A lens cassette for a lens injector includes a tubular body and a piston mobile in the tubular body to move forward a lens towards an injection cannula. The device includes a housing (30, 31) for an intraocular lens (10), an inserting zone (33) for the piston, and outlet zone (35) for the lens and its own closure element (25, 26) for enclosing the lens. The cassette is made of a material enabling sterilization of the lens enclosed in the cassette, while providing a prolonged shelf life. The cassette assembly with the lens and the injector can be sterilized in a sealed flask by gamma radiation.
