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.
