4 Detailed Reference
Foot Control of Anterior Vitrectomy Mode
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. Region 2 will provide linear control
of aspiration. 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.
For Fixed Cut vitrectomy mode, vitreous cutting is activated in Region 2. The cut rate is fixed. Each successive
outward yaw movement toggles the cutter ON or OFF. If enabled, an audible tone will indicate cutter on (double
beep) or cutter off (single beep).
For Dual Linear Cut mode, outward yaw movement provides linear control of the cut rate as a function of
footpedal displacement once it is within Region 2. The actual cut rate is displayed on the screen. When the
footpedal is released, it returns to center and the cutter is disabled. If enabled, an audible linear tone indicates
cut rate, and the pitch of the tone increases with increased cutter speed.
Reflux (if enabled) is by inward yaw movement of the footpedal.
By default, the vitrectomy cutter is On.
Pressurized Infusion Function
WARNING: This system is to be used in either air pressured infusion mode or IV Pole mode but never
both together as high intraocular pressures may result.
Note:
Specific instruction for cleaning and sterilization included with the handpiece or accessory take
precedence over these instructions.
Note: Once pressurized infusion pump is turned ON, it will continue to operate even when the function
is removed from the screen display.
Note: When using air pressured infusion, hang the bottle so that the drip chamber is close to patient
eye level.
