Title:
DRUG DELIVERY FROM CONTACT LENSES WITH A FLUIDIC MODULE
Document Type and Number:
WIPO Patent Application WO/2014/161002
Kind Code:
A3
Abstract:
A soft contact lens comprises a module embedded in a soft contact lens material. The module comprises a hydrophobic material having channels formed therein, such that a surface tension of the aqueous solution within the channels inhibits release of therapeutic agent, such as a drug, through the one or more channels. The surface tension of the aqueous solution within the channel can inhibit diffusion of the therapeutic agent through the channel. The channels may comprise a cross-sectional area and optionally a length, such that therapeutic agent is released through the channels when pressure of the eyelid increases. In many embodiments, the contact lens is configured to inhibit release of the therapeutic agent when the contact lens comprises a free floating configuration, for example when stored in a contact lens solution, such that the storage time of the contact lens can be increased substantially.
