One common technique for people who are close to or have age-induced presbyopia is to perform the surgery on only one eye, or, depending on the prescription, to apply it in different amounts. The idea is to get one eye which is good for near vision and one that is good for far vision. Sort of the same notion as bifocals, but applied directly to the eyes. Apparently the brain adjusts quickly and effectively to this and you end up feeling as though you have good vision at all ranges as long as both eyes are open.
I'm considering doing that. I'm 45 and my eyes have just begun to change. I'm still generally myopic, but so far the change just requires me to take my glasses off when doing close work. I'm going to give it a couple more years to be sure my eyes have more or less settled, then get surgery on one or both, in whatever degrees will give me the best overall visual acuity and flexibility.
If your eyes haven't actually changed yet, then it's something of a crapshoot. The idea is to adjust your vision based on guesses as to how they're going to change. That said, my optometrist says that they can make very good guesses. The only reason he's recommended that I wait is because I'm not far from the point where guessing won't be required, based on my history of general visual stability and current rate of change.
