Embodiment Construction

[0057] Embodiments of the present invention will be about image 3To describe, the Figure shows a device to aid in the establishment of a correction for correcting strabismus or heterophoria. The device comprises a measurement device 1 , an analysis unit 21 , and a simulation device 41 . The measuring device 1 and the evaluation unit 21 are connected to one another via an output interface 3 of the measuring device and an input interface 23 of the evaluation unit 21 . Furthermore, the analysis unit 21 comprises an output interface 25 via which it is connected to an input interface 43 of the simulation device 41 . These interfaces can be standard interfaces or special interfaces specially designed for connecting the measuring device 1 with the evaluation unit 21 and the evaluation unit 21 with the simulation device 41 , respectively. Furthermore, these interfaces can be connected to each other by cables or wirelessly.

Abstract

An apparatus is provided to assist in establishing a correction for correcting strabismus or phoria by testing a prescription for correcting strabismus or phoria before the prescription is actually implemented. The device comprises simulation means having: an input interface for receiving diagnostic data, classification data, magnitude data and prescription data; a generator unit for generating a right simulated image for the right eye and a left simulated image for the left eye , where the right and left simulated images each represent the same object or scene viewed by the right eye at the right viewing angle and the left eye at the left viewing angle, respectively, and the right and a left viewing angle such that the right and / or left viewing angles correspond to the viewing angles that would be achieved by applying the one or more prisms indicated by the prescription data; and a viewing device having separate displays for the patient's right and left eyes Or display sections to display the simulated image for the right eye and the simulated image for the left eye, respectively.

Description

technical field [0001] The invention relates to a device to aid in the establishment of a correction for the correction of strabismus or phoria. Furthermore, the invention relates to a method of operating a computer and a computer program product for assisting in establishing a correction for correcting strabismus or phoria. Background technique [0002] Binocular vision, or using both eyes to work together, is only possible with a well-coordinated oculomotor system and proper adjustment of the optical functions of each eye. Binocular vision may be affected when some of the mechanisms mentioned fail, as described in Bennett & Rabbetts 1998, Optics for Clinical Vision, 3rd ed. [0003] Phphoria and strabismus are abnormalities of binocular vision and are conditions that prevent a person from pointing both eyes at a fixation target at the same time. These abnormalities can be diagnosed by separating the eyes. For example, in the case of phoria, if a patient is fixating to a...
