Cataract surgery success criteria

My impression from the pre-op consultation was that if the procedure went without complications and you healed successfully, then you would forever have the 20/20 visual acuity you tested with post-op. This is because the lens, unlike the original, is synthetic with a fixed correction.
At my 18 month post-op exam, I learned that my numbers were 20/40 and 20/50 and that it was “no worries” since I could still drive legally without glasses with one eye at the 20/40 limit.
It reminded me of the pilots’ criteria of a good landing being any landing you can walk away from.
