AN APPARATUS AND METHOD FOR ACCOMMODATIVE STIMULATION OF AN EYE AND SIMULTANEOUS IPSILATERAL ACCOMMODATIVE IMAGING

摘要

An apparatus comprising an accommodative stimulation device (500), an electromagnetic wave exposure device (100), and an imaging device (400). The apparatus acquires imaging information about an eye (200) by means of the electromagnetic wave exposure device (100) and the imaging device (400) as the apparatus simultaneously stimulates the eye to undergo at least one reversible accommodative transition from any first state of accommodation to any second state of accommodation by means of the accommodative stimulation device (500). The accommodative stimulation device (500) has an axis of projection (502) that is substantially perpendicular to a visual axis of the eye (219), along which axis of projection (502) an adjustable accommodative target (503) is projected through a system of Badal optics (504), having a Badal optical axis (505) coincident with the axis of projection (502), to strike a half-silvered mirror (506) lying in a mirror plane (507) that forms an angle of about 45 degrees with the axis of projection (502) and visual axis (219) of the eye (200).
