Abstract: Method, system and computer program for measuring light diffusion in the eyeball or in the ocular region. The method comprises: projecting a punctiform light beam onto the retina; correcting low-order ocular aberrations of the eye; capturing and recording an image of the retinal plane formed after reflection of the punctiform light beam on the retina and a double passage through the ocular media of the eye; and at the same time as capturing the image of the retinal plane, performing a high- and low-order ocular aberration measurement in the plane of the pupil and performing a light diffusion measurement, combining ocular aberration measurement information with information on the image of the retinal plane. The system and the computer program are adapted for implementing the method.

Abstract: It is applied to bifocal, multifocal or progressive intraocular lenses or contact lenses, multifocal corneal ablation or other multifocal configurations, comprising means for projecting the image of a point light source on the retina of a patient and an assembly for directly recording the light reflected in said retina after the double passage of the light through the ocular means, integrating a first focus corrector device inserted in the path of the light beam guided towards the retina and a second focus correction device inserted in the light beam reflected from the retina, to be guided towards the mentioned recording means, each of said focus correction devices having independent control means for controlling the operation thereof.
