1. A method, comprising:
directing laser light from a pupil retro illumination light source onto a retina of an eye via a sample path of an optical coherence tomography (OCT) interferometer of an optical measurement instrument which includes the pupil retro illumination light source and the OCT interferometer, the laser light passing through an intraocular lens (IOL) implanted into the eye;
capturing an image of the eye from a portion of the laser light returned from the retina of the eye by an iris camera, the returned laser light also passing through the IOL;
detecting from the captured image one or more fiducials of the IOL; and
ascertaining an angular orientation of the IOL within the eye from the one or more detected fiducials.
