  Consider a complex symplectic manifold $X$ and the algebroid $W_X$ of
quantization-deformation. For two regular holonomic modules $L_i$ ($i=0,1$)
supported by smooth Lagrangian manifolds, we prove that the complex
$Rhom_{W_X}(L_1,L_0)$ is constructible and perverse and dual to the complex
$Rhom_{W_X}(L_0,L_1)$.
