  • Patent number: 12285359
    Abstract: An eye surgery surgical system includes a visualization device for visualizing the position of at least one trocar point for a trocar on the sclera of a patient's eye. The trocar serves to introduce a surgical instrument configured for surgical interventions on the fundus of the patient's eye into the patient's eye. The eye surgery surgical system also includes a computer unit which is configured to provide the position of the at least one trocar point to the visualization device. Here, the computer unit contains a trocar point computation routine configured to calculate the position of the at least one trocar point from the location of at least one surgical site in a model of the patient's eye and from geometric data relating to at least one surgical instrument introducible into the patient's eye through the trocar.

  • Patent number: 8708488
    Abstract: A method for carrying out eye surgery comprises a comparison of images recorded before surgery with images recorded during surgery in order to generate a marker which represents a target orientation of an intraocular lens or a difference between a current orientation and the target orientation of the intraocular lens. An eye surgery system respectively comprises an imaging system which is used during a surgery and has a camera, and a diagnostic system which is used before surgery and which also has a camera. The imaging system used during surgery comprises an image processing device in order to perform a computation based on the recorded images, and in order to determine a respective orientation value, from which a representation of a marker representing the target orientation of the intraocular lens is obtained.
