Abstract
A unique container system for holding and cleaning a soft contact lens over a period of time. The system includes a container base having a substantially dry cavity. A hydrophilic fixation and cleaning member is wetted and disposed within the substantially dry cavity. The contact lens is placed on the hydrophilic fixation member and held in a desired orientation while remaining hydrated due to the moisture from the hydrophilic fixation member. Also, a cover is disposed over the substantially dry cavity to enclose the hydrophilic fixation member and the contact lens during storage.
Claims26
A package for holding a contact lens over a period of time without permitting dehydration of the contact lens, comprising:
- a container base having a substantially dry cavity;
- a hydrophilic fixation member disposed in the substantially dry cavity;
- a contact lens disposed in the substantially dry cavity;
- and
- a cover disposed over the substantially dry cavity to enclose the hydrophilic fixation member and the contact lens therein, wherein the hydrophilic fixation member is wetted with a liquid.
A contact lens container system for maintain a contact lens in a usable state during a period of storage, comprising:
- a sealed container having an internal cavity;
- a hydrophilic member disposed in the internal cavity;
- a contact lens disposed in the internal cavity;
- and
- a moistening agent applied to the hydrophilic member.
The contact lens container system as recited in claim 14, wherein the moistening agent is applied to the hydrophilic member in an amount that is readily retained by the hydrophilic member to prevent the occurrence of free-flowing liquid within the internal cavity.
A method for storing a contact lens, comprising:
- preparing a container with a cavity of sufficient size to receive a contact lens;
- placing a moisture absorbent member in the cavity;
- moistening the moisture absorbent member;
- and enclosing the contact lens within the cavity.
A contact lens container system, comprising:
- a container having at least one internal cavity;
- a contact lens disposed in the at least one internal cavity;
- and
- a contact lens cleaner formed from a sponge material and disposed in the at least one internal cavity.
