Ah, that is what I was wondering!
It would kind of make sense if they’d said it wasn’t worth it - not because of any danger, but because of the limits to what would be achieved, considering the existing impairment on that side anyway.
But, if you are at all unsure what your options are, you should receive a copy of a letter to your GP, summarising the consultation, what was found, and any recommendations. That should make clear whether cataract surgery is an option, or has been rejected because it won’t make a significant improvement.
I always (actually, only nearly always - I don’t think I got the last one for some reason) get a summary of my consultation automatically. However, if you don’t receive it, it doesn’t mean there wasn’t one. Probably just that it’s gone to your GP only, but not to you. However, you’re still entitled to see it.
As your appointment was only last week, I’d give it a while (a few weeks, even) to see if anything turns up, summarising what was said. If it still doesn’t after that, get in touch with your GP, to ask if they’ve heard anything, and explain that you want to understand where you stand about surgery.
If the letter effectively says its a no-go, because your vision independent of the cataract isn’t good enough, you could still ask for a second opinion. I don’t know if there are criteria, a bit like those for DMDs, for deciding whether cataract surgery is worth it or not. But even if one consultant thinks it’s not, you still might find someone willing to do it for you.
