Yeah, get it over with. The replacement lenses never get cataracts so it's not like you might need to do it again. The surgery is the least uncomfortable medical procedure I've ever had - no pain at all, a little swelling afterwards.
Personal anecdote - had both eyes done a few months ago. My distance vision is better than it's ever been (uncorrected), close up is terrible but correctable, and I don't see any better at night... maybe a little worse.
Big thread on this in Pills subforum.
