I have heard the same as Beemer suggested, you really are better to be sure your eyes aren`t getting much worse, fairly stable vision, Or the need may arise to have it again!!!
More Cost is not good, so check that side of things first if you haven`t done so already.
My father had it done years ago with excellent results, mt last tennis partner, Sarah had it done 6 months ago & also excellent results 
Both these people are in the older age bracket thpugh, so their cases could differ from yours slightly,,,
I am no expert, just my experiences with people that have had it & been very happy with results 
GOOD LUCK
