I report on a measurement of \CP-violating asymmetries ($A_{\Gamma}$) betweeneffective lifetimes of $D^0$ or $\bar{D}^0$ in fully reconstructed $D^0\to K^+K^-$ and $D^0\to \pi^+\pi^-$ decays collected in $p\bar{p}$ collisions by theCollider Detector at Fermilab experiment. The full CDF data set correspondingto $9.7$ fb$^{-1}$ of integrated luminosity is used. The flavor of the charmmeson at production is determined by exploiting the strong-interaction decay$D^{*+} \to D^0 \pi^+$, while the contamination from mesons originated in$b$-hadron decays is evaluated and subtracted from the sample. Signal yields asfunctions of the observed decay-time distributions are extracted from maximumlikelihood fits and used to measure the asymmetries. The results, $A_\Gamma(K^+K^-) = \bigl(-1.9 \pm 1.5 \mathrm{(stat)} \pm 0.4 \mathrm{(syst)}\bigr)\times10^{-3}$ and $A_\Gamma (\pi^+\pi^-)= \bigl(-0.1 \pm 1.8\mathrm{(stat)} \pm 0.3 \mathrm{(syst)} \bigr)\times10^{-3}$, and theircombination, $A_\Gamma = \bigl(-1.2 \pm 1.2\bigr)\times10^{-3}$, are consistentwith the SM predictions and other experimental determinations.
