We present an approach to the problem of the calculation of basic paraxial parameters and the third-order aberration coefficients of thin refractive tunable-focus lenses. It is shown that aberration coefficients of the third order of the thin refractive tunable-focus lens can be completely characterized by three functions that depend only on refractive indices of fluids forming the tunable-focus lens and do not depend on the position and size of the object and the position of the entrance pupil.
