Hello,

If one believes in sterilization techniques to arrest growth and prevent
regrowth it might be best to consider ethylene oxide sterilization. This
is a well proven and accepted technique to sterilize medical instruments
including sigmoidoscopes, colonoscoscopes and bronchoscopes which
contain delicate optical components.

It is very unlikely that damage will occur on a still usable lens. I am sure
that with proper explanation contacts can be found to add a lens to a
routine load of instruments.

This method of course will not remove any already existing growth,
but will kill it.

GR.

This sounds like a very good method, but would the Ethylene oxide
diffuse into the impossibly small space occupied by the fungus in a
reasonable time?
Also, some attacks of fungus are "cemented in" in the centre of
lenses, with no visible track to the edge of the lens element. These
would, I think be inaccessible to gaseous sterilising agents.
Certainly well worth a try if available, though.
