1. A method for constructing an optical model of an individual'"'"'s eye using a plenoptic opthalmic camera, the method comprising:
- the plenoptic opthalmic camera capturing in vivo a plenoptic image of a corneal anterior surface of the individual'"'"'s eye;
the plenoptic opthalmic camera operating as a wavefront sensor to measure in vivo a wavefront produced by the individual'"'"'s eye; and
generating the optical model of the individual'"'"'s eye, wherein the optical model of the individual'"'"'s eye includes optical models of the corneal anterior surface of the individual'"'"'s eye, of a lens anterior surface of the individual'"'"'s eye, and of a lens posterior surface of the individual'"'"'s eye; and
generating the optical models comprises;
generating the optical model for the corneal anterior surface of the individual'"'"'s eye based on the captured plenoptic image; and
generating the optical models for the lens anterior surface and for the lens posterior surface of the individual'"'"'s eye based on the measured wavefront and based on the optical model for the corneal anterior surface.

Abstract
A single imaging platform for making in vivo measurements of an individual'"'"'s eye, where the measurements are sufficient to construct an optical model of the individual'"'"'s eye. The platform includes a plenoptic opthalmic camera and an illumination module. In one configuration, the plenoptic opthalmic camera captures a plenoptic image of a corneal anterior surface of the individual'"'"'s eye. In another configuration, the plenoptic opthalmic camera operates as a wavefront sensor to measure a wavefront produced by the individual'"'"'s eye.
