A processes of sterilizing a contact lens, that is immersed in an aqueous liquid and hermetically in a container, using at least 284 mJ/cmof UV radiation in the range of 240-280 nm is disclosed herein.

Method and apparatus of sterilization using monochromic UV radiation source

This invention provides a process of sterilizing a medical device, and preferably the contents of a sealed container which comprises said medical device, comprising the step of exposing said medical device to monochromatic ultraviolet radiation whereby the Dof(ATCC 7953) is at least 23.7 mJ/cmmonochromatic ultraviolet radiation at 257 nm to the spore. Further, this invention provides a process of sterilizing a medical device comprising the step of subjecting said medical device to monochromatic ultraviolet radiation wherein the minimum total energy density of said monochromatic ultraviolet radiation at 257 nm which reaches the microorganisms present on said medical device is at least 284 mJ/cm. This invention further provides an apparatus for delivering UV radiation to a medical device for sterilization comprising a laser and a scanner for the laser such that at least 284 mJ/cmat 257 nm is applied to a treatment area for said medical device. This invention provides a process and apparatus in which sterilization can be achieved in less than 20 seconds, preferably less than 15 seconds, more preferably in less than 5 seconds. The process and apparatus are efficient and continuous.

Method and apparatus of sterilization using monochromatic UV radiation source

A method and a device for removing molded soft contact lenses, high-precision intraocular lenses and the like, from the individual molds in which they are produced. Provided is an infra-red radiation or heater device constituted of silicon carbide IR-emitters, and which employs an individual infra-red emitter for each individual mold, to impart a desired thermal gradient.

Silicon carbide IR-emitter heating device and method for demolding lenses

A sterilization system comprising: radiation source; optical and/or electrical sensors; and timing means; wherein the measurement of radiation by the optical sensor is substantially synchronized based on the timing means to the start and end of each pulse of radiation from the radiation source or to the start and end of the exposure of a product to the radiation source.

Sterilization system

This invention provides a high energy radiation system which produces UV radiation comprising a selectively attenuating material which increases the ratio of desired to undesired radiation to reduce the radiation damage to a target by selectively attenuating at least 30 percent of the radiation from greater than 200 up to 240 nm which impinges upon said attenuating material, and directs greater than 50 percent of the radiation from 240 nm to 280 nm which impinges upon said attenuating material.

UV radiation system having materials for selectively attenuating radiation

This invention provides a molded polymeric object, partially or completely coated with a hydrophilic polymer which provides a wettable surface to the molded object such as a contact lens. It also provides a process for using latent-hydrophilic monomers to make molded objects with wettable surfaces.
