One thing to consider is your age.
If you are in your 20's, early 30's, 50's or 60's, it may be worthwhile.
If you are in your late 30's or 40's, you eyes may soon or are in the
process of changing. In which case the benefits may be short lived.
Do you wanat to pay for the procedure twice in a short time span?
Also, there are occassions where the procedure may need to be repeated

I had mine done in my early 40's, on the theory that when I needed
reading glasses, I just wanted magnifiers, not bifocals. I ended up
with a little "monovision" - one eye is slightly nearsighted. I'm now
46 and don't need reading glasses yet. I know they're coming, but the
monovision should put it off for a few years.
