An exact complex symplectic manifold carries a sheaf of stable categories, locally equivalent to a microlocalization of a category of constructible sheaves. This sheaf of categories admits a t-structure, whose heart is locally equivalent to a microlocalization of a category of perverse sheaves. The abelian category of local systems on a spin conic complex Lagrangian embeds fully faithfully in the heart. The sheaf of homs between two objects in the heart is itself a perverse sheaf, shifted by half the dimension of the ambient manifold. Analogous results hold for complex contact manifolds. The correspondence between microsheaves and Fukaya categories yields t-structures on Fukaya categories of conic complex symplectic manifolds, with holomorphic Lagrangians in the heart.
