  This study commenced by cross-matching data from the GAIA and OGLE telescopes
with the aim of resolving the source star, long after microlensing is finished.
The aim is breaking degeneracy between parameters of the microlensing equation,
and ultimately calculating the mass of lens. We have examined different
catalogs and found no evidence. Subsequently, employing the Monte Carlo method
and guided by sensible assumptions, we embarked a simulation to discern the
distribution of angular separation and to probe the feasibility of detecting
this phenomenon. The results revealed that a mere 0.029% of gravitational
microlensing events exhibited separations exceeding 50 milliarcseconds.
Consequently, the likelihood of observing this phenomenon utilizing the OGLE
and GAIA telescopes appears exceedingly far available. However, it is worth
noting that instruments with very high angular resolution in the range of
several tens of milliarcseconds present a viable avenue for such observations.
Finally, we proposed 60 microlensing events for which the observation of
separation is more probable based on the measured proper velocity.
