  • Publication number: 20240136066
    Abstract: A computer-implemented method for increasing a training data volume for a machine learning system for determining an initial refractive power value for an intraocular lens to be inserted is described. The method includes measuring a group of ophthalmological biometry data of a patient and determining an initial refractive power value for the intraocular lens to be inserted by a trained machine learning system. The measured ophthalmological biometry data and a postoperative target refraction value are used as input data for the trained machine learning system. The method also includes measuring a postoperative refractive results value, assigning the postoperative refractive results value to the measured ophthalmological biometry data of the patient, and determining an importance indicator value for the new training data record.

  • Publication number: 20240112028
    Abstract: A method for training a machine learning system with an extended set of patient data is described. This method includes measuring patient data and assigning ground truth data, determining the number of data pairs E/A, determining whether the number of data pairs lies below a previously defined training data threshold value, and if this is the case, carrying out the following steps: selecting a physical-optical model; using data pairs E/A in order to determine corresponding second output vectors A? from input vectors E by means of the relation function R, determining a respective difference vector, modifying the input vectors by an ?-vector; determining third output vectors of the relation function; determining modified output vectors; and training a machine learning system by means of the modified data and the original data.

  • Publication number: 20240108413
    Abstract: A computer-implemented method for training a machine learning system to determine an expected offset for a physical postoperative lens position of an intraocular lens to be inserted. The method includes determining a plurality of theoretical positions in the eye of different intraocular lenses to be inserted, the determination including a respective use of a relation and a respective lens-specific constant for the plurality of the theoretical postoperative positions.

  • Patent number: 7113428
    Abstract: Prior to the reprogramming of a selected flash memory cell of a memory cell array, electrons being removed from the memory layer (M) in the channel region (C) by Fowler-Nordheim tunneling, a lower potential for incipient programming of the memory cell is applied to the relevant word line (WLn) while the associated bit line (BLm) remains at the basic potential. What is thereby achieved is that a gate disturb occurring during the programming operation does not lead to erratic bits along the affected word line (WLn).
