  We investigate the transverse momentum effects in $\gamma\gamma\to\pi^+\pi^-$
at moderately large total center of mass energy $\sqrt{s}$ in the modified
perturbative approach. The calculation of the differential cross section using
different approximations shows that the inclusion of $k_\perp$ in the quark and
gluon propagators cannot lead to a considerable improvement of the theoretical
prediction.
