Really? I asked my last ophthalmologist if there was anything to be done about my severe floaters, and he said "no", and that I'd just have to live with them. What's the name of the procedure you had, and what are the downside risks?
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.
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).
