摘要：A method of and apparatus for improving vision and the resolution of retinalimages is described in which a point source produced on the retina of a living eye by alaser beam is reflected from the retina and received at a lenslet array of a Hartmann-

Shack wavefront sensor such that each of the lenslets in the lenslet array forms an aerialimage of the retinal point source on a CCD camera located adjacent to the lenslet array.The output signal from the CCD camera is acquired by a computer which processes thesignal and produces a correction signal which may be used to control a compensatingoptical or wavefront compensation device such as a deformable mirror. It may also beused to fabricate a contact lens or intraocular lens, or to guide a surgical procedure tocorrect the aberrations of the eye. Any of these methods could correct aberrationsbeyond defocus and astigmatism, allowing improved vision and improved imaging of theinside of the eye.
