Constellation® Vision System SECTION TWO DESCRIPTION INTRODUCTION The Constellation® Vision System is a multi microprocessor-controlled ophthalmic surgical instrument with associated memory and input/output (I/O) circuitry. The system communicates with the user via its Front Panel display, with voice confirmations, and with tones. An automatic self-test is initiated each time the system power is turned on.
Constellation® Vision System Pneumatic and Electrical Connectors The Constellation® Vision System console contains two vertical columns of connectors, located on the left side of the cassette, for surgical probes and handpieces. The right column is for pneumatic probes, and the left column is for electrical handpieces.

Constellation® Vision System Caster Wheels Four large caster wheels support the Constellation® Vision System. The wheels rotate 360º for ease of system mobility, and have a locking lever to secure the system in place. The wheels should always be locked (handle up) when the unit is in use, and unlocked when being moved. Illumination Primary illumination is provided by two independently controlled ports located just below the display.
Constellation® Vision System REAR PANEL Barcode Reader The barcode reader allows the user to quickly scan any pak or related consumable at any time during the case to input critical information about the pak into the system. The information enables the system to direct the operating room staff to any special requirements of the device, offer in-depth videos, and automatically prime the device once connected (if required).
Constellation® Vision System The operator can verify the bar code has been properly entered into the system by tapping the Consumables button to bring up the Consumables list window. In addition, all surgical tools associated with consumable (e.g., pack) will be preselected by the system. DVD/RW The DVD player/recorder allows the recording of the surgery process onto a DVD through an external device for reference or teaching purposes.
Constellation® Vision System FOOTSWITCH Functional operations of the Constellation® Vision System console are controlled by the footswitch shown in Figure 2-3. The footswitch consists of a treadle, left and right horizontal/vertical switches, left and right heel switches, and a tension adjustment knob. An advisory popup window is displayed if the footswitch is not connected.
Constellation® Vision System REMOTE CONTROL The Remote Control is a wireless, handheld, battery operated device that uses infrared light to communicate with the Constellation® Vision System console. Each of the different keys on the Remote Control unit has its own unique key code that is transmitted to the Constellation® Vision System console when the key is pressed. The transmitted key codes are translated into commands that control the Constellation® Vision System console.
