polyhexamethylene biguanide -- it’s compound used for chlorine free pool water antiseptic... or something you poor onto your eyes for weeks hoping it keeps acanthamoeba

I agree that it is inexplicably negligent not to culture the infection once an infiltrate has appeared and is threatening vision or not responding to treatment. However in this case it being Acanthamoeba it likely did not truly change long term outcome. The best medical treatment is pool antiseptic which is off label, it’s not a very effective treatment, often transplants have to be done to try and cut out the infection but they often recur as it is horrendously difficult infection to treat.

I got a few messages basically saying the same thing... outcome probably not changed even if this is caught earlier. Tough disease. What is "pool antispetic", I've never heard of that?
