I am 62 and had laser surgery about 8 years ago, best decision I ever made, and I still have 20/20 vision, I had a second op as initially had both done for distance, but still needed glasses for reading, when i went for an eyetest the optician put a disposable lens in my left eye that was the prescription of my reading glasses, well bugg*r me I could see distance and read without glasses, the brain makes the switch without you being aware so after a week like this I booked in for surgery so now my left eye is my reading eye and my right is for distance shooting etc dont worry about it go get it done
ps i was diagnosed with cancer last year and went through chemo and radio therapy and my eyes are still fine
Cheers
Ray
