Previously, fifth-order algebraic raytracing formulas for radial gradients have been derived by a method of successive approximations. These formulas are here extended to the trace of optical path lengths in radial gradients. Also, the formulas are exploited to obtain algebraic formulas for third- and fifth-order aberrations of Wood and GRIN rod lenses.
