4 Detailed Reference
Pulse Reflux:
Reflux is created by the momentary activation of a plunger on the reflux bulb.
Pulse reflux is only available with combined cassette only.
Vacuum Response
Vacuum response refers to the amount of time required to obtain the desired aspiration level. A fast response
value instructs the system to achieve the desired aspiration level in the shortest amount of time; similarly,
slow indicates that the time to achieve the desired aspiration will be significantly longer. The response can
be changed through the programming interface (see Chapter 3 ) or the
Fluidics More Screen
(see page 2-55 ). The
Advanced Vacuum System has five levels of vacuum response setting, with one being fastest response and five
being slowest response.
Foot Control of Irrigation/Aspiration
As the footpedal is initially pressed, the irrigation control valve will open to allow irrigation into the eye.
Once irrigation has been initiated and the footpedal has been depressed approximately five degrees (or as
programmed), a momentary increase in footpedal resistance will be noted signifying the transition from
Region 1 to Region 2 and the start of aspiration. Aspiration increases proportional to footpedal travel with the
maximum level being set via the
Max Vacuum
input on the touch screen. You can program Region 2 to provide
either fixed or linear vacuum control. The
Actual Vacuum
display will indicate the current aspiration level.
If enabled, an audible linear tone will indicate aspiration. The pitch of the tone increases with increased
aspiration.
Irrigation/Aspiration Setup
WARNING:
For optimum aspiration and reflux performance, the patient’s eye level must be at the same
level as (no more than 7 cm [3 in.] from) the Stellaris® PC Vision Enhancement System ’s
aspiration port. Failure to follow this procedure may result in serious and permanent patient
injury.
WARNING:
Assure the handpiece and accessories are sterilized before use as specified.
Note:
Specific instructions for cleaning and sterilization included with the handpiece or accessory
take precedence over these instructions.
1.
Turn Power on.
2.
Press any button on the Foot Control and wait until the right light turns solid green, indicting wireless
communication has been established.
