    摘要: A computer-implemented method for determining the refractive power of an intraocular lens includes providing a physical model for determining refractive power and training a machine learning system with clinical ophthalmological training data and associated desired results to form a learning model for determining the refractive power. A loss function for training includes: a first component taking into account clinical ophthalmological training data and associated and desired results and a second component taking into account limitations of the physical model wherein a loss function component value is greater the further a predicted value of the refractive power during the training is from results of the physical model with the same clinical ophthalmological training data as input values. Moreover, the method includes providing ophthalmological data of a patient and predicting the refractive power of the intraocular lens to be used by means of the trained machine learning system.

    摘要: An optical system for fluorescence observation comprises optics including an ocular 17, a camera 55, a display 69, a light source 71, an illumination light filter 84, an observation light filter 57 and a controller 35. The observation filter has multiple transmitting regions which allows light which was generated by a fluorescence to traverse for observation. The transmitting ranges are divided by blocking ranges. At the wavelength ranges at which the observation filter has a transmitting region the illumination filter has a blocking region and the other way round. The multiple transmitting regions of the illumination filter enable an improved color impression under normal light observation.The controller is configured to process a fluorescent light image obtained by the camera by identifying a contiguous fluorescent region in the fluorescent light image, generating an image including a representation of the boundary of the contiguous fluorescent region, and supplying the generated image to the display.
