Ocular solutions containing at least one macrolide antibiotic and / or mycophenolic acid provide anti-inflammatory, anti-cell proliferation, anti-cell migration, anti-angiogenesis, antimicrobial, and antifungal effects. In one embodiment, the solution is administered intraocularly after cataract surgery before insertion of a replacement intraocular lens, resulting in reduced posterior capsular opacification which may eliminate the need for a subsequent surgery. The solution may be one that is invasively administered, for example, an irrigation or volume replacement solution containing at least one macrolide antibiotic such as tacrolimus, sirolimus, everolimus, cyclosporine, and ascomycin, or mycophenolic acid. The solution may be one that is non-invasively or topically administered in the form of drops, ointments, gels, creams, etc. and may include eye lubricants and contact lens solutions.

A contact lens package includes a pair of shell members that are removably attached to each other. An sponge member positioned between the shell members contains a recess for housing a contact lens and contact lens solution. One end of each of the shell members contains a tab, the tabs being juxtaposed with one another when the shell members are attached to each other. The package is opened by pulling apart the juxtaposed tabs and separating the shell members, thereby enabling access to the contact lens. The tabs have aligned apertures for hanging the package from one end thereof. An opposite end of the package is provided with a gusset that is sized and shaped for positioning the package in a free standing position. One of the shell members contains a window for allowing visual exposure of the contact lens.

Compositions, formulations, and methods for the treatment or prevention, or decreasing the frequency of transmission of a virus (such as human immunodeficiency virus type 1 (HIV-1), Herpes Simplex virus type 1 (HSV1), or Herpes Simplex Virus Type 2 (HSV2), or other virus), or a bacterial infection (such as Trichomonas vaginalis, Neisseris gonorrhoeae Haemopholus ducreyl, or Chlamydia trachomatis, or other bacterial species), or a fungal infection, using an anionic cellulose- or acrylic-based oligomer, polymer, or copolymer. The present invention also includes administering a therapeutically effective amount of said oligomer, polymer, or copolymer, or a pharmaceutically acceptable salt thereof, or with a pharmaceutically acceptable carrier or diluent, thereof. The invention relies on the unique biochemical substitution of the cellulose or acrylic backbone such that the resultant molecule can remain molecularly dispersed in solution (or gel or other formulation) and mostly dissociated over a wide range of physiological microenvironments, such as the low pH found within the vaginal lumen, preferably from a pH of 14 to below 3.5. These specific substitutions also impart on the resultant molecule potent antiviral, anti-bacterial, and anti-fungal properties. In addition, these compositions can be used as general disinfectants for human use such as in contact lens solutions, mouthwashes, toothpastes, suppositories, or as more generalized disinfectants found in soaps, household cleaning products, paints, water treatments modalities, or can be incorporated into cosmetic, and can be used as vehicles for drug delivery, an adjuvant in a therapeutic formulation, or as a preservative. These compounds can be delivered in a liquid or solid dosage form and can be incorporated into barrier devices such as condoms, diaphragms, or cervical caps, to help prevent the transmission of STDs. The compounds of this invention can also be used in combination therapies with other classes of antiviral, antibacterial, or antifungal agent having similar or differing mechanisms of action including, but not limited to, anionic or cationic polymers, copolymers, or oligomers, surfactants, protease inhibitors, DNA or RNA polymerase inhibitors (including reverse transcriptase inhibitors), fusion inhibitors, cell wall biosynthesis inhibitors, integrase inhibitors, or virus or bacterial attachment inhibitors.

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.

A contact lens package includes a first housing member and a second housing member pivotably connected to each other. The package also includes a holding mechanism for holding a contact lens and a receiving mechanism for receiving contact lens solution. When the housing members are in a substantially co-planar orientation, the holding mechanism is positioned within the receiving mechanism. When the housing members are in a non-planar orientation, the holding mechanism is removed from the receiving mechanism such that the holding mechanism is pivotable from a closed position, in which the contact lens held in the holding mechanism is inaccessible to a user, toward an open position, in which the contact lens held in the holding mechanism is accessible to the user.

The combined contact lens case and contact lens solution container apparatus is an invention that allows a user to conveniently carry both an off-the-shelf contact lens case and a container of contact lens solution in one compact package. Because the apparatus includes both the case and container, the apparatus avoids the problem of having contact lenses on-hand when traveling but not having contact lens solution. The contact lens case easily snaps into and out of the side of the contact lens solution container requiring minimal manual dexterity. The solution container, having a solution capacity of no more than three ounces, complies with air travel carry-on requirements, allowing the user to conveniently travel with apparatus whether by commercial air travel or by other modes of travel.
