1. A system for measuring light scattering in the eyeball or eye region, of the type comprising: means for projecting a single, unpolarized point light beam in the retina of an eye of a patient; recording means for recording an image of the plane of the retina resulting from the reflected light of said point light in the retina; analysis means for analyzing said image by evaluating the light content thereof in order to perform said measurement of light scattering in the eyeball or eye region; and means for correcting low-order aberrations of the eye, including astigmatism aberrations, prior to said recording so that said image of the plane of the retina is free of the influence of said low-order aberrations.
