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.

END CASE
The End Case Screen, selected by pressing the End Case tab, displays case related
metrics as shown in Figure 2-71. It is comprised of a Summary panel area and a
tabbed interface area for displaying the various metrics associated with the case. The
screen also provides various controls for renaming the case, printing the End Case
and Laser forms, and customizing the form’s content and layout via the Setup Form
popup.
Figure 2-71 End Case Screen: Anterior Tab
Viewing of the various metrics associated with the case is accomplished by selecting
the associated tabs - Anterior, Posterior, Laser, or Consumables. Pressing the Rename
button above the tabs, displays a keyboard which enables the user to rename the case
from the default name (date of surgery).
The Print and Print Laser Form buttons are used to obtain a print-out of the End
Case Form and Laser Form respectively. The Laser Form is comprised of the End
Case Form’s first header and the Laser metrics table only. Modification of the End
Case Form’s layout and content is accomplished using the Setup Form button. When
pressed, the End Case Form Setup popup is displayed.
End Case Summary Panel
The Summary panel area lists those procedure steps that were used during the case
along with their cumulative times. For a step to be included in the summary list, work
must have been performed using the step. In most cases, work is performed when the
treadle is depressed. Therefore, steps that are defined in the procedure but not actually
used to perform work, are not be listed. This could occur, for example, if the surgeon
used the 1st step of a procedure, selected the 2nd step but did not depress the treadle,
and then proceeded ahead to the 3rd step to perform work. In this scenario, steps 1
and 3 would be included in the summary list, but step 2 would not be included in the
summary since no work was performed with it.
8065751025 2.95
Constellation® Vision System
In computing a step’s cumulative time, it is necessary for work to be done while
the step is selected in order for the current elapsed time to be added to the step’s
cumulative time. Therefore, a user may access a step and interact with the various
touchscreen controls for an extended period of time but, unless the treadle is
depressed, the current elapsed time will be discarded and will not be added to the
step’s cumulative time. If the step’s cumulative time is zero, the step will not be
shown in the step summary list.
Metrics Tabs
The End Case Metrics screens are accessed through the labeled tabs next to the
Summary panel. Tabs are provided for Anterior, Posterior, Laser, and Consumables.
When selected, each tabs displays the associated metrics for that tab as shown by the
Anterior tab in Figure 2-71. The Consumables tab displays all consumable items that
have been detected by the system.

Fragmentation Handpiece
The Fragmentation handpiece is configured to provide simultaneous vacuum and
fragmentation, or vacuum only, depending upon the console setup. The handpiece has
a stainless steel shell for improved reliability and durability. Other than attaching and
removing the needle and aspiration line, no assembly or disassembly is required.
Figure 2-75 Fragmentation Handpiece
Phaco Ultrasound Handpieces
Alcon's phaco handpieces integrate irrigation, aspiration and emulsification. The three
functions of the lens extraction step enable the surgeon to simultaneously maintain or
inflate the anterior chamber, emulsify the lens, and aspirate the lens material from the
eye.
These handpieces require no disassembly other than removal of the disposable tubing,
the ultrasonic tip, and the infusion sleeve with bubble suppression insert.
Figure 2-76 Infiniti™* Ultrasonic (U/S) Handpiece
• Infiniti™* Ultrasonic (U/S) Handpiece - This handpiece is used for ultrasonic
applications on the Constellation® Vision System with 1.1 mm TurboSonics® tips
or 0.9 mm TurboSonics® tips, including flared and/or ABS® tips.
CAUTIONS
Do not test or operate U/S handpieces unless the tip is immersed in BSS® sterile
irrigating solution or distilled water or is in surgical use. Irreparable damage to
the handpiece and tip can result if run dry.
Ensure that test chamber is filled with BSS® sterile irrigating solution before tuning
U/S handpieces. Tuning a handpiece dry may result in premature tip failure and
breakage.

WARNINGS!
Use of an ultrasonic handpiece other than the U/S, or use of a handpiece repaired
without Alcon authorization, is not permitted, and may result in patient injury,
including potential shock hazard to patient and/or operator.
Use of the U/S handpiece in the absence of irrigation flow and/or in the presence of
reduced or lost aspiration flow can cause excessive heating and potential damage
to the cornea and other tissues.

Constellation® Vision System
TurboSonics® Family of Tips
U/S tips are made of medical grade titanium alloy, and are attached to an U/S
handpiece to deliver mechanical energy to the lens, assisting in its removal by
aspiration. Depending on the needs and technique preferred by the surgeon, various
styles of tips and tip bevels are available (see Figure 2-77). Various U/S tip styles are
color coded.
• 1.1 mm U/S Tips - The standard ultrasonic tips are the original 1.1 mm
TurboSonics® tips. They are designed for use only with 1.1 mm infusion sleeves.
• 0.9 mm U/S Tips - The 0.9 mm ultrasonic tips are designed to allow entry through
a smaller incision. They are designed for use only with 0.9 mm infusion sleeves.
• Aspiration Bypass System - Tips with the ABS® feature contain a small hole in
the distal portion of the tip’s wall. This helps to maintain flow through the system
even during occlusion of the tip’s main port.
WARNINGS!
Use 0.9 mm tips with 0.9 mm infusion sleeves. Use 1.1 mm tips with 1.1 mm
infusion sleeves. Mismatch of consumable components and use of settings not
specially adjusted for a particular combination of consumable components may
create a patient hazard.
Read all package label material printed on the consumable paks prior to their use.
Standard U/S Tips - The 1.1 mm TurboSonics®tip
with the round shaft is the original, classical U/S
tip shape. The 0.9 mm has a smaller diameter shaft.
The Aspiration Bypass System - Tips with
the ABS®feature contain a small hole in the distal
portion of the tip's wall.
Kelman®Tips - The Kelman®tips have a bent shaft
which generates transverse ultrasound motion, in addition
to the conventional longitudinal motion, to enhance cutting
efficiency. In addition, the bend allows better visibility
during the surgical procedure.
Tapered Tip - The tapered ABS®tip is a combination
of the 0.9 mm tip and the flared ABS®tip. The shaft
inner and outer diameters is equivalent to straight tips,
while the distal end is comparable to flared tips. The
tapered ABS®tip has the improved holding force of a
flared tip, and the same aspiration flow characteristics
as a straight tip.
ABS®hole
ABS®hole
ABS®hole
Flared ABS®Tips - The flared tips have a larger proximal
port, providing increased holding force. They narrow in the
middle of the shaft, thus allowing smaller incisions and
improving occlusion breaks by reducing outflow from the
anterior chamber, following occlusion breaks. Flared tips
also have the Aspiration Bypass System feature, to further
enhance performance.

U/S handpieces.

BUBBLE SUPPRESSION INSERT (BSI)INFUSION SLEEVE
MicroSmooth™* Infusion Sleeves
Infusion sleeves cover the tip of the handpiece to provide irrigation to the anterior
chamber of the eye during surgery (see Figure 2-78). Infusion sleeves are used with
the Infiniti™* U/S handpiece, and with some Ultraflow™* I/A handpieces. Infusion
sleeves used with Infiniti™* U/S handpieces require a BSI (bubble suppression
insert). Infusion sleeves must be correctly matched to the specific tip type (see the
following descriptions).
Depending on the needs and technique preferred by the surgeon, various styles of
infusion sleeves are available as listed in Table 2-2.

Ultraflow™* Handpieces and Tips
The Ultraflow™* handpiece is used in I/A mode to maintain chamber pressure with
irrigation while removing cortical material via aspiration. (See Figure 2-79 and note
the band markings on the tips that identify size of tip aperture.) Some configurations
of the Ultraflow™* IT and SP handpieces also use infusion sleeves. The following
Ultraflow™* I/A handpieces and tips are available:
• Ultraflow™* IT Handpiece and Interchangeable Tips - The Ultraflow™* IT
consists of a handpiece body that accepts interchangeable tips. These tips do not
require an adapter or infusion sleeve as they contain a built-in metal infusion
sleeve.
• Ultraflow™* IT Handpiece and Threaded Tip Adapter - Reusable I/A tips with
TurboSonics® silicone infusion sleeves can be used with the Ultraflow™* IT
handpiece with threaded tip adapter.
• Ultraflow™* SP Handpiece (Single-Piece with fixed tips) - The Ultraflow™* SP
consists of a single-piece handpiece with irrigation tip, threaded tip adapter, or I/A
tip with a built-in metal infusion sleeve. Various tip configurations are available.
WARNINGS!
Use of non-Alcon surgical reusable or disposable I/A handpieces that do not meet
Alcon surgical specifications, or use of an Alcon handpiece not specified for use
with the Constellation® Vision System, may result in a fluidic imbalance. This, in
turn, may cause a shallowing or collapsing of the anterior chamber.
Exceeding the recommended level of 100 mmHg with a 0.5 mm or larger I/A tip
may cause anterior chamber shallowing and/or incarceration or tearing of the
posterior capsule.
I/A tips are not to be used with U/S handpieces.
