In this work we propose a new form of two dimensional equations describing the light beam propagation in nonlinear planar waveguides. These equations utilize nonlinear planar waveguide modes, where both effective index and field envelope depend on light intensity. We compared results obtained by the new method with results obtained by application of the three dimensional beam propagation method and classical two-dimensional equations. It has been shown that the proposed method is much more accurate than the classical one. Additionally it can be easily extend to other than the Kerr type nonlinearities.
