Patent ID: 7070276

Claim:
An apparatus comprising an accommodative stimulation device, an electromagnetic wave exposure device, and an imaging device, said apparatus acquiring imaging information about an eye by means of said electromagnetic wave exposure device and said imaging device, as said accommodative stimulation device simultaneously stimulates said eye to undergo at least one reversible accommodative transition from any first state of accommodation to any second state of accommodation, said accommodative stimulation device having an axis of projection that is substantially perpendicular to a visual axis of said eye, along which axis of projection an adjustable accommodative target is projected through a system of Badal optics, having a Badal optical axis coincident with said axis of projection, to strike a half-silvered mirror lying in a plane that forms an angle of about 45 degrees with said axis of projection and said visual axis of said eye, wherein said electromagnetic wave exposure device comprises a slit beam of a slit beam projection lamp and said imaging device comprises a Schimpflug videography system.
