The emperor Diocletian did not save the empire. It had laready been saved some 10 years earlier by the emperor Aurelian, who was given the title Restitutor Orbis (Restorer of the World) for this.
Diocletian could not save Rome, too much damage was done. However he did try to. Diocletian could not save Rome because he could not live forever, and he knew it, which may have been one of the reasons why he became the first emperor to retire. He did all he could to reorganize the empire and make it efficient again, but he had no control over what would be done to it after his death.
One way that Diocletian tried to save the Roman Empire was by dividing the Empire into two halves, West and East.
He divided the empire into provinces.
