We discuss one-dimensional difference Schrödinger equations in the complex plane. To study their solutions in the quasiclassical limit, V. Buslaev, A. Fedotov and E. Shchetka developed an analog of the complex WKB method. We consider the equation with a potential having a simple pole and study the asymptotics of its solutions in a neighborhood of this pole.
