best 3 grand i ever spent. my vision was so bad prior I couldn't see the largest letter in the test and afterwards i felt like i could have gone a few levels past the smallest on the test with no issue. after 7 years and my last exam showed I still had 20/20 vision. I can relate with the night driving halos but I had trouble driving at night prior to it too so ymmv. waking up the night of the procedure and walking the dog it was like a whole new world of clarity with the amount of detail I could see of the leaves on the trees backlit by streetlights. the first month is a pain because you can't touch your eyes and you gotta wear goggles to sleep. and being able to see in the shower is pretty cool too.
