A corrected or uncorrected human eye may be astigmatic and noncoaxial. The first-order (i.e., paraxial) character of arbitrary astigmatic and noncoaxial optical systems can be compared quantitatively in terms of the ray transference of either an anterior or a posterior converter system. This article derives equations that give the relationships between the transferences of the anterior and posterior converter systems.
