My wife has had both hers done recently (separately!) and says there is a big improvement. She was able to use her hands again fairly quickly, within 3 weeks, but she doesn't work.
I would imagine, for the kind of work we do, there would be a longer period of recovery, and as has been mentioned, going back to early would probably be a bad idea.
Take it easy, and if the scar area feels tight and starts to hurt, get someone to massage it!. According to my wife, that worked wonders.
