A guy couple decades older than myself was pulling with a cable attached to a tractor in the 80s. When the cable broke and snapped back like a metal whip, it passed through the side of his face destroying one eye and partially destroying the eye socket. This was in the closing days of when they still taught kids the number to their local police, fire department, and doctor's office, 911 not integrated everywhere nationwide. They took him to the nearest village doctor*, of mixed reputation, largely due to his bedside manner. This doctor made the first treatment, loaded him on the ambulance when he was done, and shipped him off to the hospital. Which didn't alter his work at all other than to maintain it, it was at least as good as they could do. People had a habit of forgetting their local doctor started out with the military in Korea, he had done trauma before.
I'm going to guess most of their work is cosmetic these days, but practice does make perfect.
*Sort of hard to imagine still having those. They're gone.
