After a prolapse it's common to put a stitch or two on either side of the vent to prevent it from happening again.

How old is Daisy? If she's more than a few months old and in good weight, you can take a month or so off feeding to give her time to heal up. Also when you start feeding her again offer a very small feeder which should pass more easily.

If her feces are hard make sure her humidity is up - I would keep it 70-75% - and she has plenty of water available to drink. If she takes f/t then offer her feeders wet.
