摘要： A control arrangement for an ophthalmic surgical system for phacoemulsification of an eye lens includes an optical system for generating an image of an object region. At least part of the eye lens to be emulsified and part of a needle of a phacoemulsification handpiece can be arranged in the image. An image evaluation unit evaluates the generated image in such a way that an evaluation variable is generated which is dependent on a property of a particle produced by phacoemulsification of the eye lens or is dependent on a relation of the particle to its surroundings. A control unit generates a control variable in dependence upon the evaluation variable and, with the control variable, the control unit controls an absolute value of ultrasound energy which is supplied to the phacoemulsification handpiece by an energy source for phacoemulsification of the eye lens.

摘要： A head-mounted visualization unit is provided with an at least partially light-transmissive optical system. The optical system has a first optical channel assigned to a first eye of a user and a second optical channel assigned to a second eye of the user. The first optical channel is substantially transmissive to optical radiation of a first polarization and substantially opaque to optical radiation of a second polarization, with the first polarization substantially orthogonal to the second polarization. The second optical channel is substantially transmissive to optical radiation of the second polarization and substantially opaque to optical radiation of the first polarization. A polarizer and a light attenuator are arranged in the first optical channel. The light attenuator is arranged downstream of the polarizer in a direction toward the first eye of the user.

摘要： A method and a system for generating an assistance function for an ophthalmological surgery are presented. The method includes capturing digital image data of a surgical microscope, which were generated during an ophthalmological surgery by an image sensor and which are annotated. The method furthermore includes capturing sensor data of a phaco system, which were generated during the ophthalmological surgery by a sensor of the phaco system and which are annotated, wherein the annotated sensor data and the annotated digital image data have synchronized timestamps and wherein the annotations refer in indicative fashion to a state of an ophthalmological surgery. Finally, the method includes training a first machine learning system by means of the annotated image data and the annotated sensor data to generate a learning model to predict a state of an ophthalmological surgery and, on the basis thereof, output a control signal, wherein the control signal is suitable for facilitating an assistance function in a subsequent use of the trained learning model during a prediction phase of a machine learning system.
