Appl.No PCT/EP2019/063348 Applicant HAAG-STREIT AG Inventor ZUMKEHR, Frank
An ophthalmologic device comprises a microscope (8), an illumination system (9, 22), a camera (16) positioned to record an image through said microscope, and a storage device (68). When examining an eye, the camera (16) is operated to continuously record a series of images. The images are stored in the storage device (68), each one with attributed imaging parameters describing the recording conditions of the image. When the examiner wants to retrieve images taking under examining conditions similar to the one presently used, the device is able to automatically retrieve the closest matches from the storage device (68). This allows to record, in the background, a large number of images documenting an eye's history and to retrieve them efficiently.
