Abstract
We report on the recent evaluation of the two-photon electron self energy t o all orders in the interaction with the Coulomb field of the nucleus. With the present results at hand the major theoretical uncertainty is diminishe d, which provides predictions of the ground-state energy with a relative ac curacy 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.
