This study develops an optimized finite difference iterative（OFDI） scheme for the two-dimensional（2D） viscoelastic wave equation. The OFDI scheme is obtained using a proper orthogonal decomposition（POD） method. It has sufficiently high accuracy with very few unknowns for the 2D viscoelastic wave equation. Existence, stability, and convergence of the OFDI solutions are analyzed. Numerical simulations verify efficiency and feasibility of the proposed scheme.
