A generalization of the decay law for proton emission is achieved by considering a screening effect in the electrostatic interaction. Calculations of half-lives performed on Z >= 53 proton emitters revealed a deformation dependence of the additional parameter responsible for the screening effect. A suitable functional dependence of the screening parameter on deformation significantly improves the agreement with experimental data. The prediction power of the generalized formula is tested on few observed proton emissions with unknown branching ratios and by extrapolation to available two-proton emission data.
