The present invention is generally related to a lens care system and method for disinfecting and cleaning contact lenses. A lens care system or method of the invention is based on electrolysis of an aqueous chloride solution for generating germicide species (e.g., chlorine, hypochlorous acid, hypochlorite, or combinations thereof) and subsequent in-situ electrolysis of hypochlorous acid or hypochlorite in the aqueous solution for neutralizing the generated germicide species.

A packaging system for storing ophthalmic devices such as contact lenses and methods for packaging such ophthalmic devices with solutions is disclosed. The packaging system contains an unused, ophthalmic device in an aqueous packaging solution comprising tris(hydroxymethyl)aminomethane or a salt thereof; wherein the solution has an osmolality of at least about 200 mOsm/kg and a pH in the range of about 6 to about 9.

A method is provided for operating a system to automatically conduct hygiene cycles for a confined space such an interior space of a box suitable for storing and/or carrying packaged food. The system may include a hygiene device that can be attached to the box to conduct the hygiene cycles and a mobile device that can wirelessly communicate with the hygiene device to control the conduction of the hygiene cycles. The method may include automatically collecting information related to the hygiene cycles using the hygiene device and transmitting the collected information to a network directly or through the mobile device.

A method for disinfecting contact lenses, including immersing the contact lenses in a volume of cleaning agent with about 3% hydrogen peroxide for up to 4 hrs, and immersing up to 0.7 g of a fibrous catalyst enhancer material in the volume of cleaning agent for up to 4 hrs. The fibrous catalyst enhancer material is immersed simultaneously with the contact lenses.

This invention relates to comfortable ophthalmic devices and methods of producing such devices.

This disclosure provides a method of treating an infection or inflammation of an eye of a mammal including contacting an eye with a solution comprising sterilized water and protocatechuic acid. The protocatechuic acid may be between about 0.01 wt % and 1.25 wt % in the solution. The solution may include saline. The solution may include ciprofloxacin and/or norfloxacin. This disclosure further provides a method of disinfecting a contact lens including contacting a contact lens with a solution including protocatechuic acid. The solution may include a surfactant. The surfactant may include polyethylene glycol esters of fatty acids, coconut, polysorbate, polyoxyethylene or polyoxypropylene ethers of high alkanes C12-C18. The surfactant may include poly(oxypropylene)-poly(oxyethylene) adducts of ethylene diamine having a molecular weight about 7,500 to about 27,000 wherein at least about 40 weight percent of the adducts is poly(oxyethylene).
