Contact Lens Cleaning Systems
A cleaning system configured to use a hydrogen peroxide solution to clean contact lenses. The cleaning system includes a reservoir to hold the cleaning solution and a complex base coupled to the reservoir to insure a hermetically closed reservoir environment. The complex base is separated into at least a first and a second segment. A lens holder assembly holds the lenses within the solution and is coupled to the complex base in the first segment. A motor is located in the second segment of the complex base to selectively introduce a catalyst to the cleaning solution. The cleaning system has additional features that permit the system to allow for the storage of the contact lenses by converting a neutralized cleaning solution into a storage solution to prevent recontamination.
Contact lens disinfecting system
A contact lens storage system that includes sterilized solution, at least one contract lens, a buffering agent, and a container. The sterilized solution and contact lens are physically separated from the buffering agent. Also described herein are related methods for neutralizing a sterilized contact lens solution, methods of inserting a contact lens onto an eye, and methods of disinfecting and neutralizing a contact lens.
Method for Disinfecting Contact Lenses
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.
Methods for disinfecting contact lenses with a manganese-coated disc, and related contact lens treatment systems
Contact lens treatment systems and methods for disinfecting contact lenses are described. These systems and methods utilize a coated catalytic disc, which contains a support disc and a manganese oxide present on at least a portion of the support disc. The coated catalytic disc contains 300 μg to 1800 μg of manganese, often in the form of manganese dioxide.

The coated catalytic disc contains 300 μg to 1800 μg of manganese, often in the form of manganese dioxide.
L-HISTIDINE AND VITAMIN B IN OPHTHALMIC SOLUTIONS
An aqueous ophthalmic solution comprising 0.00001 to about 10.0 percent by weight L-histidine, 1 ppm to 60 ppm hydrogen peroxide, 0.00001 to about 10.0 percent by weight of a B vitamin; and 0.1 to 500 parts per million of a preservative that provides superior preservative efficacy especially as against fungal microbes. These solutions may be employed in various ways including cleaning contact lenses, rinsing lenses while in the eye, storing lenses and in delivering active pharmaceutical agents to the eye.

SYSTEM FOR DISINFECTING CONTACT LENSES
The present invention is generally directed to a hydrogen peroxide-based lens care system for disinfecting contact lenses. Unlike hydrogen peroxide-based system known in the prior art, a lens care system of the present invention involves electrochemically neutralizing of hydrogen peroxide after any desired period of disinfection time for which contact lenses have been immersed in a hydrogen peroxide-based lens care solution.
Method for disinfecting contact lenses
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.
OPHTHALMIC DEVICES CONTAINING UV BLOCKER AND METHODS FOR THEIR PREPARATION
A method for preparing an ophthalmic device containing an ultraviolet (UV) blocker is disclosed. The method involves (a) soaking an ophthalmic device in one or more first solvent solutions to swell the ophthalmic device; (b) soaking the swelled ophthalmic device in one or more second solvents solutions comprising a UV blocker to de-swell the ophthalmic device and entrap the UV blocker in the ophthalmic device, wherein the UV blocker is a benzotriazole and (c) sterilizing the de-swelled ophthalmic device.
