Abstract
An apparatus, and related methods for sterilizing microorganisms in a container, the apparatus consists of the container including a blister formed therein and a backing material that together with the blister form a cavity in which is contained a contact lens and a preservative fluid. A flashlamp generates high-intensity, short-duration pulses of light for deactivating microorganisms within the container by illuminating the container with the pulses of light having been generated.
Claims37
An apparatus for sterilizing microorganisms in a container comprising:
- the container, wherein the container includes a blister formed therein;
- a backing material that together with the blister form a cavity in which is contained a contact lens and a preservative fluid;
- a flashlamp for generating high-intensity, short-duration pulses of light, and for deactivating microorganisms within the container by illuminating the container with the pulses of light having been generated.
An apparatus for deactivating microorganisms in a container comprising:
- a sealed contact lens container;
- a preservative fluid and a contact lens within the sealed contact lens container;
- and
- a flashlamp for generating pulses of light, portions of which transmit through at least a portion of the sealed contact lens container and deactivate microorganisms on the contact lens.
An apparatus for deactivating microorganisms in a container comprising:
- a sealed contact lens container;
- a preservative fluid and a contact lens within the sealed contact lens container;
- and
- a lamp for generating light having an energy density at least about 2.5 mJ/cm2 at wavelengths between 200 and 380 nm, wherein at least a portion of the light transmits through at least a portion of the sealed contact lens container and deactivates microorganisms on the contact lens.
An apparatus comprising:
- a sealed contact lens container containing a preservative fluid and a contact lens;
- and
- a light source for generating light, at least portions of which transmit through at least a portion of the sealed contact lens container and deactivate microorganisms on the contact lens.
A method of deactivating microorganisms comprising:
- illuminating a sealed contact lens container with light, wherein at least a portion of the sealed contact lens container is transmissive to at least a portion of the light, the sealed contact lens container containing a preservative fluid and a contact lens;
- and
- deactivating microorganisms on the contact lens within the sealed contact lens container.
A method comprising:
- providing a sealed contact lens container including a blister formed therein and including a backing material that together with the blister form a cavity in which is contained a preservative fluid and a contact lens;
- and
- illuminating the contact lens with one or more pulses of light in order to deactivate microorganisms on the contact lens.
A method comprising:
- providing a sealed contact lens container containing a preservative fluid and a contact lens;
- and
- illuminating the contact lens with light in order to deactivate microorganisms on the contact lens.
