Abstract:
A method for determining vision defects and for collecting data for correcting vision defects of the eye by interaction of a patient with an examiner, said method comprising:projecting an image into the eye of the patient with an adaptive optical system; said adaptive optical system comprising at least one adaptive optical element; said at least one adaptive optical element being configured to have its optical characteristics changed by an electrical signal, in an attempt to minimize distortions of the image as perceived by the patient; determining the presence of distortions of the image as perceived by the patient by interaction of the patient with the examiner; providing an electronic control system; said electronic control system being configured to control the optical characteristics of said at least one adaptive optical element through outputting of an electrical signal; modifying the optical characteristics of said at least one adaptive optical element through outputting of an electrical signal of said electronic control system and obtaining a modified image of the image in the eye of the patient, in an attempt to correct for the distortions of the image as perceived by the patient; evaluating said modified image by interaction of the patient with the examiner; repeating said modifying step and said evaluating step and obtaining a modified image having minimized distortions as perceived by the patient; determining the optical characteristics of said at least one adaptive optical element, as modified, resulting from said modified image having minimized distortions as perceived by the patient; and computing vision correcting data for the eye being examined, from said optical characteristics of said at least one adaptive optical element, as modified, resulting from said modified image having minimized distortions as perceived by the patient.
