I do have a little more information than when I first posted as I have had a consultation with a retinal specialist. He said that yes, the surgery would indeed take care of the floaters.
Surgery for an epiretinal membrane is apparently not indicated unless it is interfering with vision, which in my case it is not yet (except under blue light - but that’s only happened twice, when I was trying to read a web page with a blue background and when I went to a theatre production that temporarily bathed the stage in blue).
Ordinarily, I have to think about the splotch and consciously look for it under natural light to see it; it’s visible but unobtrusive under ordinary evening conditions when a room is artificially illuminated. I think my brain has simply adapted to it and ignores it.
The funny thing, though, is that it is constantly gradually changing shape, which is kind of weird. I don’t know if that is usual. Anyway, the doctor recommended waiting 6 months and reevaluating then.
It seems like a balancing act on whether/when to do surgery, as outcomes are better earlier on in membrane development (per my doctor). On the other hand, like any surgery it comes with risk, so another good option is to avoid surgery forever if the visual disturbance is minor and doesn’t affect functioning.
markn_1, I don’t know what your girlfriend’s eye health is like, but I have retinal degeneration, which makes me more likely to have a poor outcome if I do have the surgery. At least it is a one-eye-at-a-time procedure, assuming both eyes are affected in the first place, so even a worst-case outcome won’t result in losing sight in both eyes.
The other thing is that recovery from surgery sounds like a pain in the ass. I forget the details now, but you do have to lie still for a few days, I think, and then you have some movement restrictions for weeks or months afterwards (but check this out, I think I have purposefully forgotten so that I don’t worry about it).
Let’s see, the only other thing I can remember learning is that one cause of the membranes is having had surgery to fix retinal tears. That’s me in spades - I can’t even count how many surgeries I’ve had, but I would guess between 4 and 6.
Anyway, the doctor and I agreed to take a six-month wait-and-see approach. I’m scheduled for a new evaluation in February. So far, my thought is to not ever do surgery, if the membrane (or membranes - only one eye is really affected now but I can see the ever-so-faint traces of one starting in the other eye too, when the light is just so) doesn’t interfere with normal activities. But since outcomes are better with earlier surgery, if that starts to change I’ll probably do surgery right away.
I hope that helps, and best of luck to your girlfriend. And sympathy to you - as a sufferer from exceptionally bad floaters myself, I know just how annoying they can be.
