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.

The invention relates to an arrangementwith an OCT devicefor scanning an object region volumearranged in an object regionwith an OCT scanning beam, comprising an itemwhich has a sectionthat is arrangeable in the object regionand is localizable in the object region volumeby means of the OCT device, and having a computing unitconnected to the OCT deviceand having a computer program for determining a 3-D reconstruction of the object region volumeand determining the location of the portion of the objectin the object region volumeby processing OCT scan information obtained with the OCT deviceby scanning the object region volume. According to the invention, the computer program has a calculation routine for determining a target area in the 3-D reconstruction of the object region volume, which routine determines a reference variable for the objectfor the target area. The computer program contains a path planning routine that uses a criterion to calculate an optimal path for objectto the target spatial position, the criterion being a shadow measure that quantifies the occurrence of shadows caused by objectin the calculated 3-D reconstruction. The invention also relates to a computer program and a method for determining a 3-D reconstruction of an object region volumein an object region

The present invention relates to a system for acquiring and visualizing OCT signals, comprising an OCT system and a display means designed for the time-resolved display of image data. The system further comprises a control unit configured to drive the OCT system to acquire a time-resolved OCT signal of a selected field of view of the sample and to determine a time-resolved OCT image on the basis of the acquired time-resolved OCT signal and a specifiable virtual viewing direction and to display the time-resolved OCT image on the display means. The present invention also relates to a corresponding method for acquiring and visualizing OCT signals.
