An ophthalmic surgical system, comprising: a 3D camera optically coupled to a surgical microscope; a VR headset to be worn by a surgeon; and a VR data processing unit configured to communicate with the 3D camera, the VR headset, and a surgical apparatus for performing ophthalmic surgery on a patient, wherein the VR data processing unit is configured to: project a real time video screen of video received from the 3D camera into the VR headset; project a surgical apparatus information screen into the VR headset showing a current context of the surgical apparatus; project a surgical apparatus input control screen into the VR headset that provides the surgeon with direct control over the surgical apparatus; the VR data processing unit is further configured to: project a patient information screen into the VR headset to provide the patient information directly to the surgeon during ophthalmic surgery; control which ones of the real time video screen, the patient information screen, the surgical apparatus information screen, and the surgical apparatus input control screen are visible in the VR headset based on inputs indicating head movements of the surgeon as detected by the VR headset, characterized in that the VR headset comprises a microelectromechanical systems gyroscopic sensor with sensor outputs for being read by the VR data processing unit to detect side-to-side and up-and-down movements of the surgeon's head, wherein each of the real time video screen, the patient information screen, the surgical apparatus information screen, and the surgical apparatus input control screen is assigned a corresponding range of rotation and/or inclination angles of the surgeon's head, and wherein the VR data processing unit is configured to control which ones of the real time video screen, the patient information screen, the surgical apparatus information screen, and the surgical apparatus input control screen are visible in the VR headset by: receiving the sensor outputs from the VR headset indicating the measured rotation angle and/or inclination angle of the surgeon's head; and displaying each of the screens having a corresponding range of rotation angles and/or inclination angles covering the measured rotation angle and/or inclination angle of the surgeon's head in the VR headset. a 3D camera optically coupled to a surgical microscope;
