We developed and experimentally implemented an ABCD matrix formalism for describing structural transformations and orbital angular momentum of structured Laguerre-Gaussian beams in an astigmatic optical system containing cylindrical and corrective spherical lenses. It was shown that the matrix formalism not only agrees well with the method of integral astigmatic transformations, but also significantly expands the scope of its application. It was found that a corrective spherical lens is capable
