I'm 50 now and I had lasik done 3 years ago. For 2 years prior I had stopped being able to use contacts, age related dry eyes I guess.
Right after the surgery I had better than 20/20 vision but I've lost a bit of that. Not enough to make me want to endure a touch-up, not yet anyway.
I find during the day and outside I feel I have perfect vision. Into the evening as I get tired and the light drops I notice a real change in acuity. No issues with halos after the first month. To watch TV across the room I need glasses now with a minimal prescription.
The operation was pretty pricey at $3800. But the ability for me to go through most day without glasses, not even for reading, is priceless.
