BLUE 400 and BLUE 400 S are accessories to the surgical microscope and allow the fluorescence observation of fluorophores with an excitation peak between 400 nm and the fluorescence emission observation comprising the spectrum in a spectral band of 620 - 710 nm. The ZEISS BLUE 400 and BLUE 400 S are surgical microscope accessories used in fluorescent visualization of suspected grade III and IV gliomas during neurosurgery.

The BLUE 400 and BLUE 400 S are fluorescence accessories to qualified surgical microscopes, intended to allow intraoperative viewing of malignant glioma tissue grade III and IV under fluorescence. The overall system is comprised of excitation (illumination) and emission (observation) filters to detect fluorescence and are optimized in conjunction with the drug to pass light between 620 – 710 nanometers. The BLUE 400 S filters allow the surgical microscope to produce excitation light in a wavelength range covering at least 400 - 410 nanometers that excites an approved optical imaging agent and enables the surgeon to observe the emitted fluorescent signal in the oculars or on a display. Fluorescence of marked brain tissue helps visualization of tissue associated with Grade III & IV glioma during neurosurgeries. Compared to the blue visualization of the surrounding non-fluorescent tissue in the BLUE 400 image, BLUE 400 S is designed to visualize the surrounding nonfluorescent tissue more similar to white light impression, while tumor visualization of grade III and IV glioma remains consistent. With the visualization of non-fluorescent anatomy in an almost white light impression, BLUE 400 S is expected to allow PplX visualization with less frequent switching between fluorescence and white light imaging modes. BLUE 400 and BLUE 400 S can be installed only into qualified ZEISS surgical microscopes. For these accessories to be used with a qualified ZEISS surgical microscope, the critical components of the surgical microscope need to fulfill the clinically relevant parameters for the Indications for Use of BLUE 400 and BLUE 400 S.

CALLISTO eye is an assistance system that processes real-time video images that can be displayed on the CALLISTO eye Panel PC for viewing by the surgeon and the surgical staff in the operating room. The same video images can be viewed by the surgeon through the eyepiece of the connected surgical microscope. CALLISTO eye provides Assistant Functions displaying treatment templates as screen overlays and Cockpits displaying patient and device information as screen overlays. Both functions assist the surgeon during procedures such as limbal relaxing incisions, capsulorhexis, and alignment of toric intraocular lenses (TIOL). All treatment templates are based on preoperative clinical data of a particular patient and shall be defined by the surgeon prior surgery. These templates can be displayed on the CALLISTO eye Panel PC, through the eyepiece of the surgical microscope equipped with a data injection system (IDIS (WITH VERSION 5.0 RELABELED AS ADVISION)) of the ARTEVO 750 or on a 3D monitor connected to the ARTEVO 850. While using "ASSISTANCE markerless" configuration, CALLISTO eye can utilize the preoperative diagnostic data from the Zeiss IOLMaster and may provide the reference and target axis as required to align a toric intraocular lens without the otherwise required ink marks. Transmission of the diagnostic data from the IOLMaster to CALLISTO eye takes place via USB stick or via a data network connected to a DICOM compatible MIMPS server such as FORUM. The DICOM functionality allows the indirect communication with other DICOM compatible diagnostic devices and patient information systems to exchange patient data (e.g. medical devices work lists).
