Figure 5.16 – PHACO Screen
Vitrectomy
The WHITESTAR SIGNATURE™ System uses a pneumatic guillotine vitrectomy
cutter. The handpieces are designed for cutting vitreous during anterior segment
surgery and operate in conjunction with the Irrigation/Aspiration mode. The cutting
speed can be changed on the touch screen. There are four adjustments related to the
Vitrectomy mode:
• Aspiration Rate
•Vacuum
•Cut Rate
•Footpedal
CAUTION: THE PHACO HANDPIECE AND VITRECTOMY
CUTTER MUST NEVER BE ACTIVATED WITH THE TIPS IN THE AIR.
EXPOSING THE TIP TO AIR DRASTICALLY REDUCES THE USEFUL LIFE
OF THE HANDPIECE. IF POWER IS TO BE INTRODUCED TO THE PHACO
HANDPIECE OR VITRECTOMY CUTTER, THE TIPS MUST BE IN A TEST
CHAMBER FILLED WITH A BALANCED SALT SOLUTION, IN A
CONTAINER OF BALANCED SALT SOLUTION OR IN THE PATIENT’S
EYE.
