AB  - We have developed a phenomenological approach which describes very well the pi(0), eta and eta' meson production in the two-photon interactions. The simultaneous description of the pi(0), eta and eta' meson two-photon form factors is consistent with data in the spacelike region, with the exception of the pi(0) BABAR data. The obtained form factors are implemented in the event generator EKHARA and the simulated cross sections are presented. Uncertainties in the measured form factors coming from the model dependence in Monte Carlo simulations are studied. The model predictions for the form factor slopes at the origin are given and the high-Q(2) limit is also discussed.
