Systems and methods for cleaning a hard-coated ophthalmic lens and stripping the hard-coating of the hard coated ophthalmic lens in a single pass process are disclosed. The hard-coated ophthalmic lens is sequentially treated with a cleaning solution, an alkaline solution, and a stripping solution. Ultrasonic power is applied to the solutions and the ophthalmic lens during the process. The resulted ophthalmic lens has substantially no sign of chemical attack or residual hard coating or varnishes thereon.

A device for cleaning a contact lens includes a lid, a base portion and a drawer unit detachably coupled to the base portion. The drawer unit includes a container holding a volume of fluid therein. The device also includes a vibration generator for generating an oscillatory motion on the container, where the oscillatory motion induces turbulence in the fluid with sufficient force to dislodge deposits from a lens immersed in the fluid. The device also includes a circuit board secured to the base portion and a light source for generating radiation to disinfect the dislodged deposits in the fluid. A suspension secures the light source to the circuit board and a resonance frequency of the suspension is offset from a frequency of the oscillatory motion.

The present invention is of using contact lenses for photodynamic inactivation of germs, a product, and a method of treating fungal keratitis by applying the same. The contact lens is to continuously release a photoactive solution containing a photosensitizer such as rose bengal and hydrogen peroxide to the ocular surface. The photosensitizer would be activated while these contact lenses are applied and exposed to daylight or other artificial lights in the environment. After activation, the photosensitizer will produce singlet oxygen and reactive oxygen species to inhibit the growth of fungi, thereby treating fungal keratitis without having the patient experiences eye pain or discomfort. Moreover, since the photoactive solution excludes any antifungal agents, the contact lenses for photodynamic inactivation of germs of the present invention can not only improve drug-resistant fungal keratitis but also prevent the germs from developing antimicrobial resistance.

A chip sanitizing device comprises an area that is substantially enclosed and includes a sanitizing unit comprising a germicidal bulb and a power source. One or more chips is placed within the device and after the germicidal bulb is activated the one or more chips is sanitized. In another embodiment of the invention a chip rack is modified to include a sanitizing unit comprising a germicidal bulb, a power source and a fan stored in a housing attached to the chip rack. The slots are modified to contain openings to allow ultraviolet light to reach the chips sitting atop the rack. The ultraviolet light may sterilize microorganisms such as germs and bacterium found on chips. A fan is used to provide circulation and may increase the likelihood of germs and bacteria coming into contact with the ultraviolet light. In a further embodiment of the invention a lid is provided that substantially covers the chip rack and stores the sanitizing unit. In a further embodiment, the inner surfaces of a lid or housing may be covered with reflective material to increase the likelihood that the ultraviolet light comes into contact with germs or bacteria.

An ultraviolet irradiation apparatus includes: a first substrate; a second substrate; electrodes disposed directly or indirectly on the first substrate; a dielectric layer covering the electrodes; a sealant joining together the first and second substrates; a light-emitting layer that is disposed directly or indirectly on the dielectric layer and/or a surface of the second substrate; and a reaction vessel disposed directly or indirectly on a surface of the second substrate. The reaction vessel includes a tubular structure, an inlet channel and an outlet channel. The tubular structure has a ratio ha/hc of 5 to 10, where ha is a diameter of a circle inscribed in an inner bottom surface of the tubular structure, and hc is an inner height of the tubular structure.
