It's not bacterial, it's amoebic.
I think you're being unduly skeptical and I can't find a reason beyond your own intuition, which doesn't really hold much weight against first hand accounts from individuals and trusted news sources without any clear bias or motivation to be misleading.
My point is: who is more likely to get an infection? The people that sterilize their cuts and scrapes, or the people that don't? Same thing here: for such a tiny subset of total contact wearers, it's unlikely that it has nothing to do with your lens hygiene. I doubt any one of the 125 AK sufferers in the UK were following recommended lens care/application to the letter. That does not seem unduly skeptical to me.
Her case just make have been incredibly invasive? The medication may have pushed the infection deeper into the eye or surrounding tissue, or it may have developed resistance.
My point is that I'm betting those 125 are a subset of people that don't use their lenses according to best practices.
A friend of mine got it just a month ago, and luckily he got it diagnosed correctly right away. He woke up in the morning with no issue, and by the evening he was in the emergency room. A quick diagnosis saved his eyesight despite the very aggressive onset, the fastest the doctor treating him had ever seen.
Maybe AK is silently established in the eye sometimes, and an abrasion or some other factor allows it to take hold in the cornea? My friend was soldering with bad ventilation and he probably got plenty of microscopic resin particles in his eyes, which might have caused abrasions? His AK took hold right on the edge under the contacts.
Are you saying this never happens? No on is saying it is a huge problem, just that people should be aware of it.
A. wearing dailies for only a day at a time
B. didn't shower/swim with them
It is incredibly unlikely that a bacterial infection from tap water would be able to manifest itself on an otherwise healthy eye in less than 16(?) hours. The timeframe/exposure just doesn't add up for me.
