1. An apparatus for treating an eye, the eye having a cornea and a lens, the lens having an anterior surface and a posterior surface, the apparatus comprising:
a tomography system for measuring a tomography of the eye; and
a processor comprising a tangible medium configured to:
determine a curvature of the cornea, a curvature of an anterior lens surface, and a curvature of a posterior lens surface of the eye based on the measured tomography of the eye;
determine an optical axis of the eye in response to one or more of the curvature of the cornea, the curvature of the anterior lens surface, and the curvature of the posterior lens surface;
determine an anterior optical node of the eye in response to the curvature of the cornea, the curvature of the anterior lens surface, and the curvature of the posterior lens surface, wherein the anterior optical node is located along the optical axis; and
determine a posterior optical node of the eye in response to the curvature of the cornea, the curvature of the anterior lens surface, the curvature of the posterior lens surface, and one or more indices of refraction of the lens of the eye, wherein the posterior optical node is located along the optical axis, and wherein the anterior and posterior optical nodes have a property that a ray aimed at one of the anterior and posterior optical nodes is refracted by the eye such that it appears to have come from the other one of the anterior and posterior optical nodes and with the same angle with respect to the optical axis.
