Karahisarithis was a doctor of medicine by profession. He became patriarch after Papa Eftim I resigned in 1962 due to ill health. While his father survived until 14 March 1968, Eftim II took over office ruling from 1962 until his death on 9 May 1991. He was succeeded by his younger brother Papa Eftim III.
