OPERA (Oscillation Project with Emulsion tRacking Apparatus) was a long-baseline experiment at the Gran Sasso laboratory (LNGS) designed to search for $\nu_{\mu}\to\nu_{\tau}$ oscillations in appearance mode. OPERA took data from 2008 to 2012 with the CNGS neutrino beam from CERN. The observation of five $\nu_{\tau}$ candidates allowed assessing the discovery of $\nu_{\mu} \to \nu_{\tau}$ appearance in the CNGS neutrino beam with a significance of $5.1\sigma$.
The data analysis is still ongoing, with the goal of improving the sensitivity to the sterile neutrino search in the $\nu_\mu \to \nu_{\tau}$ and $\nu_\mu \to \nu_e$ appearance channels and oscillation parameters with reduced statistical uncertainties. Current results will be presented and perspectives discussed.
