It is shown that a higher-order correction improves the accuracy of the zeroth order WKB phase for a heavy-ion optical potential. The WKB phase shifts, correct to the first order in ${\ensuremath{\hbar}}^{2}$, agree with those obtained from a quantal optical model code.NUCLEAR REACTIONS Higher-order WKB calculation $^{58}\mathrm{Ni}$($^{18}\mathrm{O}$, $^{18}\mathrm{O}$'); ${E}_{\mathrm{lab}}=60$ MeV; calculated reflection coefficients.
