Russ; At 66 I had both eyes done one month apart.Having been nearsighted all my life I opted for both eyes the same. I see 20/20 in my left eye,and 20/22 in my right. NOTE I am a left handed shooter, with a right master eye. No problems before or after. The reason for this post is that I had Radial surgery about 5 years before and was told that having the surgery, made it more diffacult to get the correct settings for the cateract surgery. they measured 3 times over a 6 week period before doing it. sfq
