Abstract
A system includes a model eye and an optical measurement instrument, which includes: a corneal topography subsystem; a wavefront sensor subsystem; and an eye structure imaging subsystem. The subsystems may have a common fixation axis, and be operatively coupled to each other via a controller. The optical measurement instrument may perform measurements of the model eye to verify correct operation of the optical measurement instrument for measuring one or more characteristics of a subject's eye. The model eye may include an optically transmissive structure having a front curved surface and an opposite rear planar surface, and a material structure provided at the rear planar surface of the optically transmissive structure and having a characteristic to cause a speckle pattern of a portion of a coherent light beam that is directed back out the front curved surface of the optically transmissive structure to have a bright-to-dark ratio of less than 2:1.
