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.

Abstract: Aspects of the present invention provide an ophthalmic lens comprising at least one regressive and at least one non-regressive rotationally symmetric optical design element. The regressive and non-regressive optical design elements can be combined so as to form a desired optical power profile for the lens while simultaneously exploiting the different relative orientation of the astigmatic vectors of the constituent regressive and non-regressive design elements, thereby resulting in reduced unwanted astigmatism. The regressive and non-regressive rotationally symmetric optical design elements can be positioned on different lens surfaces and in optical communication or can be collapsed onto the same lens surface. The regressive and non-regressive rotationally symmetric optical design elements can each contribute to the total add power of an ophthalmic lens.

Abstract: Aspects of the present invention provide progressive addition lenses (PALs) and techniques for designing PALs that result in improved visual performance for the wearer. PALs of the present invention can have vision zones with widths that are more in line with the actual or functional sizes used by wearers. PALs of the present invention can also introduce controlled amounts of unwanted astigmatism into one or more vision zones. By allowing vision zones to include manageable levels of astigmatism, the resulting PAL can avoid the harsh build-up of astigmatism typically found in conventional PALs at the periphery of the channel and viewing zones. Further, PALs of the present invention can be designed using a merit function to achieve an optimized iterative design that accounts for astigmatism vector orientation and not simply astigmatism magnitude as is the case with conventional PAL design.
