CASE One Touch
To simplify the programming of the CASE function, you only need to define the basic CASE
parameters once. You can adjust the CASE function quickly and easily from the CASE One
Touch settings on the surgical screen. Use these controls to change the CASE functionality
for greater efficiency (up arrow) or more control (down arrow) to suit any particular
combination of cataract density, surgical technique, or personal preference.
When CASE is On, use the One Touch buttons to adjust the CASE parameters.

Reflux
Reflux is the controlled back flow 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 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 foot pedal switch. This causes fluid to
be expelled from the aspiration line into or towards the eye.
The reflux is active until the foot pedal switch is released.
