We consider the T-matrix near the unitarity limit and the energy dependence of the saturation momentum. We discuss the solution to the Kovchegov equation, or equivalently, to the BFKL evolution in the presence of a single saturation boundary. We include some of the correlations missed in the Kovchegov equation by solving the BFKL equation in the presence of two boundaries. The T-matrix now turns out to be frame-independent, which was not the case for the solution in the case of a single boundary, and it doesn't show the scaling behavior of the solution to the Kovchegov equation. We find for the saturation momentum an energy dependence which differs from the one following from the Kovchegov equation.
