If I understand correctly, this is quite different, as such IOLs offer no accommodation, but only different areas with varied optical powers, which isn't as convenient (ever seen an elderly man trying to read a menu hanged on the wall?).

You're right. I was thinking of accommodation (I remember reading someones anecdote about having one installed) but didn't remember well enough or check carefully enough.
