  • Patent number: 11109754
    Abstract: Provided is an ophthalmic measurement device with which it is possible to obtain an area in which a measurement can be taken without moving an optical system. With reference to an optical path length of an illumination optical system with which light is focused on the eyeground when the refraction value is 0 D, the positions of two light sources are set to achieve a setting in which the optical path length becomes slightly shorter. By doing so, it is possible to cope with measurement of refractive properties in a large area without employing structures that allow a lens system of the illumination optical system and the light sources thereof to be moved. In addition, by selecting one of the two light sources so that a clearer Hartmann image can be obtained, it is possible to further increase the precision of the refractive properties to be measured.

  • Patent number: 11016301
    Abstract: An auto-focus head-mounted display (HMD) dynamically generates aberration-adjusted images based on measured accommodation of user's eye(s). An aberration-adjusted image is an image distorted to correct aberrations that would otherwise occur at a retina of the user due to image light passing through optics of the HMD. The aberration-adjusted image corrects the aberrations of the HMD and “accounts” for the aberrations of the eye so that the resulting retinal image is free of optical aberrations due to the HMD but preserves correct eye optical aberrations that are correlated with a current accommodative state of the eye.

    Abstract: A method for determining the visual acuity, wherein two spaced outer markings and an orientation marking lying between but not on a straight connecting line are displayed to the user on a display in an individual test as part of a plurality of tests. The user is to move the orientation marking on the display perpendicularly to the straight connecting line by actuating the device until the user perceives the marking as lying on the straight connecting line. Afterwards, the electronic device registers the effective distance between the orientation marking and the connecting line. At least two tests are carried out in which the outer markings are arranged along the same main axis, and at least the vertical main axis and the horizontal main axis are measured. After the manipulation, the effective distance from the individual tests of the series is used for ascertaining the visual acuity.

  • Patent number: 10769765
    Abstract: Method and system for lensless, shadow optical imaging. Formation of a hologram shadow image having higher spatial resolution and lower noise level is accomplished by processing image information contained in multiple individual hologram shadow image frames acquired either under conditions of relative shift between point light source and the detector of the system or under stationary conditions, when system remains fixed in space and is devoid of any relative movement during the process of acquisition of individual image frames.

  • Patent number: 10758119
    Abstract: A system automatically captures a fundus image with limited user interaction such that the fundus image has one or more desired characteristics. The system can retrieve at least one image from an image capture device, process the at least one image digitally to generate a processed image, detect at least one point of interest in the processed image, determine that each of the at least one point of interest is representative of a corresponding feature of the eye, and obtain a fundus image of the eye based on the at least one image.

  • Patent number: 10761602
    Abstract: A retinal imaging system includes a projector, an imaging device, and a controller coupled to an eye tracking system under test. The projector emits a light pattern to be delivered to a pupil of an eye, a location of the pupil being estimated by the eye tracking system under test. The imaging device captures one or more images of a retina of the eye illuminated with at least a portion of the light pattern. The controller determines one or more eye tracking parameters based on the captured one or more images of the retina. The controller compares each determined eye tracking parameter with each of estimated one or more eye tracking parameters, wherein values for the one or more eye tracking parameters are estimated by the eye tracking system under test. The controller characterizes each estimated eye tracking parameter based on the comparison.

  • Patent number: 10733725
    Abstract: Embodiments of the present invention provide a method, system and computer program product for fundus drawing analysis in ophthalmological diagnostics. A fundus drawing analysis for ophthalmological diagnostics method includes first specifying a set of ophthalmological pathological features of an eye and then generating a database query with the specified set. Thereafter, the database query may be submitted to a database of ophthalmological meta-data regarding different fundus images generated for different eyes so as to retrieve a sub-set of the ophthalmological meta-data. Then, those of the different fundus images that correspond to the sub-set are identified and the identified different fundus images are retrieved. Finally, the retrieved fundus images are displayed in a user interface of a medical image processing host computing system along with a statistical indication of a number of each of the ophthalmological pathological features present in the retrieved fundus images.

  • Patent number: 10709326
    Abstract: Postoperative lens position is predicted on the basis of known measured values, such as the corneal thickness, the depth of the anterior chamber, the eye length, and the distances of the capsular bag equator and/or of the lens haptic from the anterior surface of the lens. In addition, the calculation also takes into account the attitude of the intraocular lens, for which purpose additional parameters of the pseudophakic eye are used that have not previously been taken into consideration. The proposed method is suitable for a more exact prediction of the strength and nature of an intraocular lens to be implanted in a pseudophakic eye in the context of cataract surgery or of a refractive intervention. The method is based on the use of suitable calculation methods, e.g. geometric optical formulae, or of ray tracing.
