Reflux
Reflux is the controlled backflow of fluid through the aspiration port of the
handpiece. Reflux is used to gently release or dislodge unwanted material from the
handpiece tip. Reflux can also be used to “tent” the incision site to allow easier tip
insertion. Reflux pressure depends on bottle head pressure (IV pole height and
gravity) for the FUSION™ Fluidics pack (OPO70), and as such, is not intended to
clear a clogged handpiece. However, reflux can be used to identify a blockage.
The reflux action can be programmed on any available footpedal switch. This
causes fluid to be expelled from the aspiration line into or towards the eye.
The reflux is active until the footpedal switch is released.
The FUSION™ Fluidics pack (OPO70):
• allows an inter-connection of the irrigation line to the aspiration line, so that
sterile balanced salt solution can enter the aspiration line.
• has no time restriction for Reflux as there is no pump reversal
The DP pack (OPO71):
• includes support for the vacuum tank used in the Venturi vacuum system
• does not support inter-connecting the irrigation line to the aspiration line.
Therefore, only previously aspirated fluid is being refluxed.
