A diagnostic device detects a layer boundary which facilitates the determination of layer thicknesses in the human eye. The device has a light source with a beam path which is designed to guide at least one measuring beam of the light source from the object plane of the light source into an intersecting region of the measuring beam with an optical axis in the eye, and an actuator designed to move the intersecting region along the optical axis. The beam path guides the measuring beam from a layer boundary into the sensor unit. An evaluation unit is designed to estimate and/or determine a layer thickness between a first and a second layer boundary.

A liquid lens system comprises a liquid dropwhose shape can be influenced by electrical fields. A plurality of electrodes are arranged annularly around the liquid drop. The liquid lens system may be employed in an artificial eye, an accommodation measuring instrument and a dioptric telescope.

Artificial eye and measuring instrument for measuring the accommodation of an eye

A liquid lens system comprises a liquid drop 10 whose shape can be influenced by electrical fields. A plurality of electrodes are arranged annularly around the liquid drop. The liquid lens system may be employed in an artificial eye, an accommodation measuring instrument and a dioptric telescope.

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.
