I had my cataracts done in 2019 (late 50s)
I went from -7 to having good distance vision and needing reading glasses for close work.
My sister had hers done and kept her close vision as she does crafts where the natural magnification of very short sight was a positive.
The actual procedure wasn't painful, although I did find it uncomfortable staring into the bright light whilst unable to blink, but that wasn't for long.
I had mine done a few weeks apart.
Took a couple of days off work not because I couldn't see with the one that was done, but because the contrast of having one eye with very short sight and one with distance vision was very disorienting. I ended up poking out one lens from my glasses and blocking it off so I could work on computer with the other eye.
I love being able to see my face in the bathroom mirror, go snorkelling and see the fishes without having to get prescription lenses, go running in the rain etc.
I wasn't able to run for a couple of weeks after each was done.
I have varifocals now just to allow me to switch between reading a book, reading off a monitor and seeing distance just by using different part of the glasses.
I do miss a bit that close vision when you could read tiny print taking off your glasses, but use my phone magnifier app as replacement for that.
