Can Lasik be touched up so that I can see mid distance again?

I had lasik surgery about 6 weeks ago and my eyes are about 20/20 (+.5 in my left and +.25 in my right) for distance but my mid-distance is not what I expected. If I walk around with +1's on everything is very good (would still need reading glasses but I'm 54 so I expected that). Once my eyes are healed and if my mid-distance doesn't improve, can I get an enhancement that would make me see as if I'm wearing +1's? The +1's don't hamper my distance vision by much.
