Vision after cataract surgery

[Thetexan]

Just had double lensar laser cAtaract surgery.  Great result. 20/20 both eyes.  However far distant buildings, trees, signs etc is slightly blurry.  Like looking through a camera that is slightly out of focus.  

I made the assumption that 20/20 (described To me as far vision) meant FAR Vision, I.e. 20 feet and beyond (or infinite focus).  I’m beginning to believe 20/20 means just that, visual acuity measured at 20 feet, not a half mile.  This doesn’t solve my problem since as a pilot I need the buildings and other planes at a distant to be crisply clear.

My question is this... am I right?...can I have 20/20 and still need glasses to  fine tune the FAR distant vision.

No you are not right.  At 20 ft or 6 meters  the light enters the eye parallel no matter how far away you are looking.  That is why we test at 20 ft. At some distances things are too small for the eye to resolve and no glasses help the vision.  You may have residual myopia/astigmatism and glasses for distance may improve your vision 'way off'   You will need to discuss this with your surgeon and have a glasses test then see how much improvement the glasses make for driving/flying.
