1. A corneal pachymeter system, the corneal pachymeter system comprising: a light source configured to illuminate a cornea of an eye; a plenoptic detector, the plenoptic detector positioned at an angle relative to the eye, the plenoptic detector configured to detect both intensity and direction of light of an image of the light source scattered from the cornea and generate plenoptic image data representing the image including both the intensity and the direction of the light detected by the plenoptic detector; and a processing system coupled to the plenoptic detector, the processing system configured to: analyze the plenoptic image data to determine corneal thickness of the eye by computationally tilting the image of the light source derived from the plenoptic image data to more accurately correspond to a Scheimpflug orientation angle.
