[QUOTE="SWHandldr, post: 2785231, member: 114858"] I had keratotomy (astigmatism correction) at the same time as cataract surgery in 2008. Pre-surgery I was 20/400 - extremely nearsighted - and terribly astigmatic. Post surgery, somewhere there was a ticked off 25-year-old cos I had his vision: 20/25 in my near eye and 20/15 for distance. Astigmatism is now non-existent. Red dots are a [B]dot[/B] insead of a disorted star. As for cataracts, I had my left (dominant) eye corrected for 'front sight' distance (a little more than arms length) & my non-dominant eye for infinity. This works for instrument panels in vehicles & aircraft as well as handgun use. Outdoors, even with sunglasses, pupil contraction provides sufficient depth of field (like stopping down a camera lens) that the difference in sharpness between 'near' and 'far' eyes is barely perceptible & not bothersome. My brain automatically uses my 'non-dominant' eye for distance vision. For reading fine print, details on camera lenses or other close work, a pair of readers in the +1.50 to 1.75 diopter range moves my focus zone from arms length to 8-12 inches.
