Cassette and injector for flexible intraocular lens and method for injecting such lenses

摘要

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.
