It's up to you (and your ophthamologist). As
PaulH says, there's more to it than just the correction. I had mine done just over a year ago; my wife doesn't want to get hers taken care of because I need, and she will almost certainly need, reading glasses. Funny thing, while my eyes are now 20/20 and hers are corrected to 20/20, I'm the one who has to read the small signs far off. Getting rid of the cloudiness I didn't really know was there makes that big a difference.
FWIW, I bought a new pair of cycling glasses (with corrective lenses) the spring before my surgery in the fall; about $750 sunk there. I got a summer of riding with those glasses, and I don't regret cataract surgery when I had it.
