Patent ID: 7284862

Claim:
An ophthalmic adaptive-optics instrument comprising: an observation target disposed for a subject eye to fixate; an aberration-compensating element disposed in the observation path of said subject eye and receiving a pupil image through relay optics, wherein said aberration-compensating element is driven by a control signal and is capable to compensate low and high order aberration of said subject eye; a wavefront-sensing device sensing the aberration of said subject eye via said aberration-compensating element; control electronics coupled to said wavefront-sensing device to generate said control signal to drive said aberration-compensating element; an eye motion-sensing device sensing the movement of said subject eye; and a motion-compensating mechanism coupled to said eye motion-sensing device and disposed to compensate said movement of said subject eye, such that said pupil image stays stationary with respect to said aberration-compensating element; wherein said aberration-compensating element compensates said aberration of said subject eye while said motion-compensating mechanism compensates said movement of said subject eye.
