I had the same condition about 15 years ago and I was told it would be life-long. I think it lasted a few months, although I have only had the Beck systems for a couple of years so I cannot claim they helped.
If it is bacteria you could use the Silver pulser to remove it from your blood, plus the magnetic pulser especially all around and over the eyes and also make your own silver water which will kill bacteria that is in or on the eyelid if you spray your eyes a few times a day.
In my opinion having used the systems for a while I would say they are very safe for the purpose.
