    Might be a silly question, but - is everyone's -1.50 vision the same? I
    had cataract surgery, and it resulted in -1.50, so my intermediate
    vision is very good, but distance is very blurry. However, I've spoken
    to people who have that vision and are able to drive. I would NEVER
    attempt to drive, since my distance vision is so bad. I was wondering
    if this is because my vision prior to surgery was approx. -6.50. I'm
    starting to worry that my few weeks immediately following surgery was
    in front of a computer - starting to obsess that perhaps that affected
    the final outcome.

  2. There is a difference between quantity of vision and quality of
    vision. Quantity can be measured in diopters (-1.50) or Snellen
    (20/whatever). Quality is more likely measured with contrast
    sensitivity or wavefront aberrometer analysis. Two people with the
    same quantity can have very different quality and the other way

    Considering that if all went well with your cataract surgery and you
    have a good IOL, the quality of your vision is probably pretty good.

    I think the difference between you and your friend is the tolerance
    for driving with poor vision. Rather than obsessing about your
    vision, I'd obsess about not being on the road when your friend is
    driving. 8^)

    Hear hear, hitting the nail on the head.
    Vision acuity or the left error in refraction after surgery (LASIK,LASEK,PRK
    or implants) are not the only issues to consider BEFORE having surgery

    I understand that contrast sensitivity can be lost thru refractive
    surgery, but can it also happen in cataract surgery?
