A method of and apparatus for improving vision and the resolution of retinal images is described in which a point source produced on the retina of a living eye by a laser 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 aerial image 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 the signal and produces a correction signal which may be used to control a compensating optical or wavefront compensation device such as a deformable mirror. It may also be used to fabricate a contact lens or intraocular lens, or to guide a surgical procedure to correct the aberrations of the eye. Any of these methods could correct aberrations beyond defocus and astigmatism, allowing improved vision and improved imaging of the inside of the eye.

1. Apparatus for use in performing surgery on the living eye to correct for aberrations of the living eye, comprising:a light source for generating a reflected point source image of the retina of said living eye; an optical detector for receiving said reflected point source image and for converting said point source image to corresponding digital signals; a digital data processor for calculating wave aberrations of the eye, using said digital signals; and a surgical device connected to receive the calculated wave aberrations from said digital data processor for performing surgery of said living eye.
