I'm not sure what they do but those that I know who've had them done
invariably seem to have greatly improved vision, certainly for distance.
Some need 'reading' glasses but not all.

The lenses you get will be fixed focus.

You can choose what that focal length will be.

I have glasses for distance - I wear vari-focals, the lower part are
plane lenses. I asked my optician about laser treatment. She said that,
while I don't have any signs of cataracts (virtually) everyone will
develop them at some point due to people living longer and, at my age, I
might as well wait until I get new lenses for cataracts! Five years on
I'm still cataract free.
