I had both mine done just before lockdown, one on the NHS and one privately as the NHS said my second eye didn't qualify! The difference has been amazing. I hadn't realised I had been looking through a brown fog until afterwards when I discovered I was wearing a pretty lilac-coloured skirt, not the grey one I thought I had!! Now I can drive in the dark and match colours. I still can't quite get used to being slightly long-sighted rather than very short-sighted, and I still have to cope with very many floaters, but the difference overall is just amazing.
Friends who have had theirs done recently tell me that the anaesthetic is given in the form of drops rather than by injection, and that the NHS only uses non-corrective replacement lenses I had the choice of lens three years ago. Back then, I had my hospital assessment on a bank holiday Saturday, and, much to my amazement, on the following Tuesday I had a phone call from the eye clinic saying they'd had a last-minute cancellation, and could I be at the hospital within the hour!! Absolutely I could!!
I think aftercare is a bit different too, and some people even have both done at once as a result!
Go for it and enjoy your improved eyesight for the rest of your life
