Viscous Fluid Control (VFC) Mode
The VFC (Viscous Fluid Control) mode provides pressure at the front panel VFC
connector for fluid injection (i.e., silicone oil), or vacuum for extraction, through the
VFC tubing set to a syringe. Using vacuum, the VFC mode also provides a means of
extruding fluid through the VFC consumables.
CAUTION
Always use Alcon-supplied Viscous Fluid Control Kits and follow all Directions
for Use. Do not use VFC without the plunger/stopper supplied with the kit. Do
not aspirate fluids directly into the console; this will cause damage to the console,
increase risk of electrical shock, and void all warranties.
