Priming for
Vitrectomy
Before you perform vitrectomy, we recommend you prime the handpiece in order
to reduce the chance of errors. Each time you select vitrectomy mode you are
prompted to prime the vitrectomy handpiece. If you do not need to prime, press
Bypass.
To prime the handpiece:
1. Attach the irrigation and aspiration cassette pack tubing together.
2. Press Prime on the Prime/Tune screen.
3. Press the VIT button to enter VIT mode.
4. Follow the instructions on the screen.
5. Press Start Vit Prime. The screen closes automatically when the handpiece is
primed.
Note: If you must perform vitrectomy in the middle of phaco surgery, perform
steps 3 through 5.
