We report on the recent evaluation of the two-photon electron self energy to all orders in the
interaction with the Coulomb field of the nucleus. With the present results at hand the major theoretical
uncertainty is diminished, which provides predictions of the ground-state energy with a relative
accuracy of about 10(-6) for the hydrogenlike uranium and lead systems. This allows for
high-precision tests of quantum electrodynamics (QED) in strong fields that are expected to be
experimentally available in the near future.
