Eye floaters are like that. They don't go away but you get used to them being there.
Changed my life, I thought I was living in a small crowd of fruit flies.
I have similar issues and 5 years in, problems are only getting worse (perhaps combined with pigment dispersion syndrom making it worse, but not on the path to glaucoma, at least not yet).
To be honest, I don't know where I'd rank on an objective severity scale. My floaters often make it difficult to read, and I've got one that can lodge in the wrong place for long enough to make driving feel a little scary. That's maybe not bad enough - given the risks, which I don't know right now - to argue against it. I'm not necessarily questioning the doctor's judgment - he's maybe right! - just mad that he didn't even tell me about this procedure.
