Yes but the next decade or so wont be one of expansion, but reaction. Stemming the civil war that led to Turkish settlement in Anatolia doesnt solve the issues of the Normans, Pechenegs, and potentially the Bulgarians.
But it does give more breathing room. The army's probably still going to have to be rebuilt; the tagmata were much smaller than before and there are too many mercenary troops that are way too expensive.
But after a decade or so of fighting off new invaders the ERE should be in a position to continue its hegemony.
