I had mine done 5 years ago and still see 20/15 in my right eye. My surgeon was one of just a handful doing the FDA approval for WaveFront eye mapping. Evidently it worked well enough to allow him to do a subtle mono vision enhancement for each eye. My right eye, being my dominant eye, was corrected for sharpness from armslength to (theoretically) infinity. My left was corrected for sharpness close-up out to about 300 feet. He did this to hold the need for reading glasses. Since I was 38 at the time and approaching the age where presbyopia would start to set in, I'd say it was a good call. The dual corrections compliment each other and there is seamless transition from close-up to long distance. Regular checks show no changes and everything is just fine. No dry-eye, no halos, and great night vision. I'm happy I did it and glad my surgeon was so attentive and innovative.
