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.
APPARATUS AND METHOD FOR DETECTING MOISTURE IN A VACUUM CHAMBER
A method of operating a sterilization system having a vacuum chamber for sterilizing instruments, the chamber connected to a reservoir of sterilant by a valve in a closed state, is disclosed. The method comprises placing the instruments in a non-sterile state in a sterilization pack, opening the chamber, placing the pack into the chamber, closing the chamber, withdrawing a first volume of air from the chamber, changing a volume of liquid water into vapor, opening the valve, introducing the sterilant into the chamber, withdrawing the sterilant from the chamber, introducing a second volume of air into the chamber, opening the chamber, removing the pack from the chamber, and removing the instruments in a sterile-state from the pack. The method may also include taking a baseline humidity measurement while the pressure within the chamber is a first pressure, lowering the pressure within the chamber to a conditioning pressure, maintaining the conditioning pressure for a dwell time, increasing the pressure within the chamber, acquiring a second humidity measurement from within the chamber, and comparing the baseline humidity measurement to the second humidity measurement.
Ophthalmic device packaging solutions comprising a poloxamine/erythritol mixture
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.
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.
COMFORTABLE OPHTHALMIC DEVICE AND METHODS OF ITS PRODUCTION
This invention relates to comfortable ophthalmic devices and methods of producing such devices.

Disinfection system of contact lens
A disinfection system of a contact lens comprising immersing the contact lens in a disinfecting solution containing hydrogen peroxide in a concentration of 1 to 10% and neutralizing the hydrogen peroxide in the disinfecting solution through contact with a metal catalyst, where the disinfecting solution contains an organic carboxylic acid or a salt of the organic carboxylic acid, the organic carboxylic acid having a structure in which a hydroxyl group and a carboxyl group are bonded to one carbon atom; the disinfecting solution is adjusted to have a pH of 6 to 8; and the disinfecting solution after the neutralization is adjusted to have an osmotic pressure of 250 to 350 mOsm.
Contact Lens Dispenser
Contact lens dispensers are provided including a pens dispenser having an interior and a dispensing end. A delivery screw is provided in the interior of the tubular housing. The delivery screw has a thread pitch and a plurality of contact lenses, one contact lens per pitch. Upon actuation of an actuator, each contact lens moves along the thread by a distance of one pitch and a single contact lens is dispensed from the dispensing end of the tubular housing. A case and disposable foil contact lens cartridge are also provided as a re a case and disposable contact lens foil spool, wherein actuation of push-buttons dispense contact lenses ready for immediate application onto an eye.
