Congrats on good results!
With regard to enhancements, I was about -.75 in each eye after the first Lasik. Many would be delighted with that.
Had the enhancement (5 seconds or so of zap in each eye) at Doc's suggestion, and it made a WORLD of difference for me.
It was the difference in "it's ok, I guess" to "fantastic!" for me.
There are risks and rewards that must be balanced for each person, but the reward for me has been great so far.
Sounds like you are closer to perfect than I was, so you may be good to go. I post my experience in case others are considering an enhancement.
