Contact lens packaging
A contact lens package includes a first layer, a support coupled to the first layer, a lens, and a second layer. The support includes a scaffold and a porous member attached to the scaffold where the porous member includes a curved surface. The lens includes an anterior surface and a posterior surface, and the posterior surface of the lens is disposed on the curved surface of the porous member. The second layer is coupled to the first layer to seal the support and the lens between the first layer and the second layer.
1. A contact lens package comprising:
a first layer;
a support coupled to the first layer, the support including a dome-shaped scaffold and a dome-shaped hydrogel is formed around the domed-shaped scaffold;
a lens including an anterior surface and a posterior surface, wherein the posterior surface of the lens is disposed on the dome-shaped hydrogel; and
a second layer coupled to the first layer to seal the support and the lens between the first layer and the second layer.
2. The contact lens package of claim 1 , wherein the first layer is a rigid plastic tray and wherein the second layer is a foil lid stock.
3. The contact lens package of claim 1 , wherein the scaffold is integrally formed with the first layer.
4. The contact lens package of claim 1 , wherein the first layer is a foil lid stock and the second layer is a rigid plastic blister.
5. The contact lens package of claim 1 , wherein the dome-shaped hydrogel is a sintered material.
6. The contact lens package of claim 1 , wherein the domed-shaped hydrogel exhibits antimicrobial properties.
7. The contact lens package of claim 1 , wherein the hydrogel is capable of absorbing at least 5% of a buffered saline solution.
8. The contact lens package of claim 7 , wherein the buffered saline solution contains antimicrobial agents that can be diffused into the lens.
9. The contact lens package of claim 7 , wherein the buffered saline solution contains wetting agents that can be imparted onto the lens.
10. The contact lens package of claim 7 , wherein the buffered saline solution contains antihistamine that can be diffused into the lens.
11. The contact lens package of claim 7 , wherein the buffered saline solution contains nutraceuticals that can be diffused into the lens.
12. The contact lens package of claim 7 , wherein the buffered saline solution contains osmoprotectants that can be diffused into the lens.
13. The contact lens package of claim 7 , wherein the buffered saline solution contains additives selected from the group consisting of erythritol, glycerol, mannitol, sorbitol, and propylene glycol.
14. The contact lens package of claim 7 , wherein the buffered saline solution contains one or more block copolymers comprising a combination of polyethylene oxide and polypropylene oxide blocks.
15. The contact lens package of claim 1 , wherein at least one of the first layer and the second layer include perforations.
16. A contact lens package comprising:
a base;
a cover coupled to the base, the base and the cover defining a receptacle for a contact lens;
a support disposed within the receptacle, the support including a dome-shaped hydrogel and a dome-shaped scaffold, wherein the dome-shaped hydrogel is formed around the dome-shaped scaffold; and
a contact lens including an anterior surface and a posterior surface, wherein the posterior surface of the contact lens is disposed on the domed-shaped hydrogel.
17. The contact lens package of claim 16 , wherein the support is coupled to the base.
18. The contact lens package of claim 16 , wherein the support is coupled to the cover.
19. The contact lens package of claim 16 , wherein the hydrogel is capable of absorbing a buffered saline solution.
