Abstract
A method for improving the antibacterial efficacy of an ophthalmic solution, particularly a solution for the care of contact lenses, comprises providing an article molded from a plastic resin including an inorganic carrier retaining antibacterial metal ions, and placing the ophthalmic solution in contact with the plastic resin.
Claims20
A method for improving the antibacterial efficacy of an ophthalmic solution comprising:
- providing an article molded from a plastic resin including antibacterial metal ions in an inorganic carrier;
- and
- placing the ophthalmic solution in contact with said article, whereby said antibacterial metal ions leach into said ophthalmic solution.
In a contact lens case comprising at least one cell including a cavity adapted to store a contact lens and an ophthalmic solution therein, and a sealable cover for said cavity, the improvement wherein the cell is molded from a resin including antibacterial metal ions in an inorganic carrier, wherein said antibacterial metal ion is leachable from said resin to an ophthalmic solution stored in said cell.
A combination comprising:
- a container for storing an ophthalmic solution molded from a resin including antibacterial metal ions in an inorganic carrier;
- and
- an ophthalmic solution contained in said container,
- wherein said antibacterial metal ions are leachable from said resin to said ophthalmic solution.
A combination comprising:
- a container for storing an ophthalmic solution;
- an ophthalmic solution contained in said container;
- and
- a substrate molded from a resin including antibacterial metal ions in an inorganic carrier in contact with said ophthalmic solution in said container,
- wherein said antibacterial metal ions are leachable from said resin to said ophthalmic solution.
