Abstract
A method for use with an eye examination instrument for automatically aligning the eye under examination with the instrument optical axis. An operator initially aligns the instrument optical axis manually with the eye under examination. A first adjustment to the initial alignment is then automatically made in the optical train of the instrument so as to laterally align the eye under examination. The size of the lateral adjustment is determined, and an axial adjustment of the optical train is automatically effected by an amount controlled by the size of the lateral adjustment so as to axially align the eye under examination, whereby the requisite axial adjustment is determined directly from the accomplished lateral adjustment without the need for intervention of the operator.
