    Abstract: A method of removing a lens forming material deposited on a lens forming surface (1) of a reusable glass mold for forming ophthalmic lenses, in particular contact lenses or intraocular lenses, comprises the steps of providing a plasma (2), exposing the lens forming surface (1) of the reusable glass mold to the plasma (2) for removing the lens forming material deposited on the lens forming surface (1). The plasma (2) is generated under atmospheric pressure and potential-free, or is generated under reduced pressure.

  • Publication number: 20140230732
    Abstract: A transporting apparatus for simultaneously transporting at least two substrates into a substrate-treatment apparatus to be treated in a vacuum-treatment apparatus has at least two carrier apparatuses mounted for rotation in relation to a common axis and offset axially in relation to one another. At least one retaining frame configured for supporting at least one substrate is arranged on each of the two carrier apparatuses. Each retaining frame is configured to be shifted, by rotary movement of the two carrier apparatuses about the common axis, into mutually opposite regions of a treatment unit with the two carrier apparatuses spaced apart axially from one another sufficiently such that the treatment unit is arranged between the two carrier apparatuses.
