A method and assembly for removing an intraocular lens from an injection molded mold half. With the method and the assembly, first spill ring material is removed from the mold half. Subsequently, the mold/lens-assembly is subjected to an oscillating mechanical load without substantial deformation of at least a part of the mold half that is in direct contact with the lens body. The oscillating mechanical load has an oscillation frequency which is in a range that excites the mold/lens-assembly to break bonds between the intraocular lens and the mold half. After that, a static mechanical push force is exerted on the bottom side of the mold half to at least partly separate the intraocular lens from the mold half.

According to the present invention, there is provided a contact lens assembly comprising a contact lens having an outer edge, a flash ring disposed around the outer edge of the contact lens and a connecting portion connecting the flash ring to the contact lens, wherein the thickness of the connecting portion is less than the thickness of the outer edge of the contact lens. There is also provided a contact lens assembly comprising a contact lens having an outer edge, a flash ring disposed around the outer edge of the contact lens, and a connecting portion connecting the flash ring to the contact lens wherein the mass of the flash ring is at least forty times greater than the mass of the contact lens, suitably at least sixty times greater than the mass of the contact lens. There is also provided a contact lens injection molding apparatus comprising first and second molding parts moveable relative to each other between a compressed and an uncompressed position, wherein in the compressed position, an outer edge of the first molding part is disposed 1 to 50 μm from an outer edge of the second molding part.
