Method And Device For Measuring Imaging Errors In The Human Eye

Abstract

The invention relates to a device for measuring imaging errors in the human eye, wherein substantial scanning of the lens of the eye with a light beam or laser diode determines the measuring accuracy of local refractive power. Measuring accuracy of locally dependent refractive power is achieved by a two-dimensionally refractable tilting mirror which is embodied in the form of a microscanner mirror with the aid of a piezomotor for positioning and by electrically controllable liquid lenses. As a result, it is possible to manufacture the measuring device as small as possible, enabling it to be integrated in to a processing laser in order to monitor the result of treatment with a laser during individual adaptation of contact lenses, intraocular lenses or surgical correction of the retina in situ and to calculate data of a required correction.
