We consider a scattering theory for difference operators on perturbed with a long-range potential . One of the motivating examples is discrete Schrödinger operators on -periodic graphs. We construct time-independent modifiers, so-called Isozaki–Kitada modifiers, and we prove that the modified wave operators with the above-mentioned Isozaki–Kitada modifiers exist and that they are complete.
