It’s so rare that the trainees never see any patients with it. The consultant asked me if I was OK for all the doctors there that night to have a look. They were fascinated but I was in a fair amount of pain!
I had to apply drops of what was effectively bleach to my eye for six months to ensure it went. Very painful. The diagnostic process was incredibly painful too. I can’t wear lenses anymore as I think my cornea is permanently damaged. Luckily my vision is back to normal but took nearly a year to recover.
Don’t sleep in your lenses. Don’t wear lenses in the hot tub!
