Vitrectomy Cutting Rates
Note: Each time you select the vitrectomy mode you are prompted to prime the
vitrectomy handpiece. Refer to Chapter 4, Equipment Operation, Priming
for Vitrectomy for detailed information.
You can vary the Vitrectomy Cut Rate of the vitrectomy cutter from 50-2500 CPM
(cuts per minute) in increments of 50 CPM between 100–1000, and 100 CPM
between 1000–2500 CPM.
Some surgeons prefer a higher rate, which allows the surgeon to perform the same
amount of cutting with smaller “bites” of vitreous. This minimizes motion and is
gentle on the tissue.
To adjust the cut rate
1. On the Cut Rate panel, press the Up or Down arrows to increase or decrease
the cut rate.
2. Press Settings to select either Linear or Panel cutting methods. The Settings
window opens.
Note: Side Vit is only available for use with a single linear foot pedal.
3. Press Linear or Panel button.
4. Press Finished to close the window.
