The LCD screen is the communication interface between
the surgeon and the system. It provides the surgeon with
system status and parameters by displaying text and icons
relevant to the current operating state. The background color
of this screen is gray when the system is in the Standby
state and green when is in the Ready state. When the laser is
fired, "Laser On" is display in a red box at the bottom of the
screen.
Figure 2-2 shows a typical screen that may be displayed on
the LCD. Each screen displayed by the system is described
in detail later in this section. System messages (advisories,
errors, and warnings) are listed in the Troubleshooting
section of this manual.
Figure 2-2
Typical PurePoint®
Screen
Laser Ports 1 and 2
Dual SMA connectors are provided on the front panel to connect the PurePoint™
Laser to the desired delivery system; i.e., Slit Lamp adaptation, Laser Indirect
Ophthalmoscope (LIO), or Endoprobe/Aspirating probe. Each port has an Radio
Frequency Identification (RFID) reader that can identify Alcon RFID enabled probes
and automatically set up the default power and time parameters for the specific probe.
Laser fibers without RFID must be identified by the operator when prompted on the
display.
Port Illumination Ring
The Laser Ports are surrounded by a ring of LED's that provide background
illumination for the port and enable the user to visually verify the following items:
• Indicates that the port is selected.
• Indicates that an unidentified probe has been inserted into the port.
• Indicates that a fault has been detected on the port and the port is no longer
available.
Port Available Illumination Color: BLUE
If no probe is connected to a port, the Port Illumination Ring is illuminated in the
color blue.
Selected Port Illumination Color: GREEN
If an identified probe is inserted into the port and the port is selected, the Port
Illumination Ring is illuminated in the color green.
Unidentified Probe Indication Color: ORANGE
If a probe is inserted into the port and is unidentifiable by the system, the Port
Illumination Ring is illuminated in the color orange, indicating that the probe must be
identified before it can be used.
2.2
8065751131
A message is displayed as shown in Figure 2-3 prompting
the user to identify the probe as one of three instruments
displayed in the menu options.
After the user has identified the probe:
• The Port Illumination Ring is illuminated in the color
green if the port is the only port with an identified probe.
• The Port Illumination Ring is not lighted if the other port
already contains an identified probe. The port with the
newly-identified probe is not the selected port. The Port
Selection Button must be pushed for the probe to be
Figure 2-3
selected.
Disabled Port Indication Color: RED
Unidentifiable Probe
Selection Screen
If the PurePoint™ software determines a port cannot be
used due to a mechanical or software fault, the Port Illumination Ring is illuminated
in the color red.
Port Selection Buttons
When each port has an identified probe, pressing one of the Port Selection Buttons
selects the associated port. The Port Selection Buttons are active only when there are
identified probes in each port. In all other cases (such as an unidentified probe in one
port, only one port being used, no identified probes in a port, etc.) the PurePoint™
software will take the correct action.
When a selection is made, the LED surrounding the desired port illuminates green. If
selecting a port for the first time after starting the system with an identified endoprobe
or slit lamp attachment, a screen is displayed asking the user to confirm that the Dr.
Filter is in place.
Emergency Switch
Pressing the Emergency Switch turns off the laser system immediately. To restore
power, pull the Emergency Switch to the out position. The system will return to the
Standby mode.
Keyswitch
The Keyswitch is a two position switch where the key can be removed only in OFF
position. In the OFF position, the power to the laser is shut off. Switching to the ON
position turns the laser system on and the system will display the Standby screen.
8065751131
2.3
LIO Illumination Power Knob
The LIO Illumination Power knob adjusts the brightness of the LIO illumination
beam (if an LIO power cable is plugged into the LIO Power Port port, a LIO fiber is
connected to a laser port, and the port is selected). Turning the knob right makes the
LIO illumination beam brighter and turning the knob left makes the beam dimmer.
When the LIO illumination beam reaches its maximum brightness, continuing to turn
the knob to the right has no effect. Similarly, when the LIO illumination beam reaches
its minimum brightness level, continuing to turn the knob to the left has no effect.
Aiming Beam Intensity Knob
The Aiming Beam Intensity knob adjusts the intensity of the the red laser aiming
beam. The system saves the intensity setting for each port. Therefore, when a laser
port is selected, the aiming beam intensity setting is the same as the last time the port
was selected. In addition, when the laser system has completed initialization, the
aiming beam intensity for the selected port is the same as the last time the system was
turned on.
•
•
•
Turning the Aiming Beam Intensity knob clockwise increases the intensity
towords the maximum (under 1 mW).
Turning the knob counter-clockwise decreases the power until it effectively turns
off.
Turning the knob further in either direction has no effect on the power of the
aiming beam.
LIO Illumination Power Port
The LIO illumination power cable connector is inserted into this port.
Menu Knob
The Menu knob allows the user to highlight and select a menu item shown on
the display. The knob rotates to move the highlighted field on the display, and the
highlighted item is selected by pressing the knob.
•
•
•
•
•
2.4
Turning the Menu knob clockwise moves the highlighted field to the right (or
down).
Turning the Menu knob counter-clockwise moves the highlighted field to the left
(or up).
Continuing to turn the knob after highlighting the last menu item has no effect.
On menus in which several choices are required, turning the knob highlights the
space, but the knob must be pushed in to make a selection. A choice must be made
in each line or column.
For menu items containing values that can be modified, turning the knob right
increases the value and turning the knob left decreases the value. Once the
maximum or minimum value for a setting has been reached, turning the knob in
that direction has no further effect.
8065751131
Standby/Ready Button
The Standby/Ready button switches the system between Standby and Ready modes.
The screen background changes color for each mode (gray for Standby, green for
Ready mode). In addition, each mode has an associated LED that illuminates when
that mode is active.
WARNING!
In Ready mode, pressing the footswitch will fire the laser.
To transition the system from Standby to Ready mode, press the Standby/Ready
button once. The transition proceeds as follows:
• The LCD background color flashes between gray and green for the 2 seconds.
• During those same 2 seconds, the Standby LED turns off, and the Ready LED
flashes on/off.
• After the transition, the LCD background color remains green and the Ready LED
stays on indicating that the system is in Ready mode.
Various conditions prevent the system from transitioning to Ready mode including
the following:
• Footswitch disconnected
• No identified probe connected
• Remote interlock open
• Tethered Dr. Filter disengaged
• The LCD is displaying a menu screen
Pressing the Standby/Ready button while the system is in Ready mode, immediately
returns the system to Standby mode.
The Interval Time Knob
The Interval Time is the time between treatment shots when the treatment mode is set
for Repeat mode. The Interval Time knob can adjust the interval time to the following
values:
• 30 ms to 100ms in 10 ms steps
• 100 ms to 300 ms in 50 ms steps
• 300 ms up to 1 second duration in 100 ms steps.
The Interval Time Knob functions as follows:
• Turning the knob clockwise increases the amount of time between pulses
(interval).
• Turning the know counter-clockwise decreases the amount of time between
pulses.
• Turning the knob counter-clockwise from the maximum interval time (1000 ms)
places the laser in Single Shot mode. Afterwards, turning the knob clockwise has
no effect.
• Turning the knob clockwise from Single Shot mode will place the laser into
Repeat mode with the interval time set to 1000 ms.
• Pressing the Interval Time knob sets the laser to Single Shot. Pressing the knob
again returns the system to Repeat mode using the previous Interval time. In CW
mode, turning or pressing the Interval Time knob has no effect.
NOTE: In Continuous Wave (CW) mode, the Interval Time knob is disabled
and interval parameter on the diplay is grayed out.
8065751131
2.5
The Pulse Duration Knob
The Pulse Duration Knob sets the duration (exposure time) of the laser emission and
it functions as described below:
•
•
•
•
•
Turning the knob clockwise increases the exposure time up to 2000 ms.
Turning the knob past the 2000 ms setting or pushing the knob places the system
in Continuous Wave (CW) mode. In CW mode, the Interval Time knob is
disabled.
Turning the Pulse Duration knob counter-clockwise from CW mode returns the
system to the previous mode: Single Shot or Repeat.
Turning the knob counter-clockwise decreases the exposure time. The lowest
available exposure time is 10 ms.
The Pulse Duration Knob adjusts the exposure time to the following values in
milliseconds:10, 20, 50, 100, 150, 200, 250, 300, 400, 500, 700, 1000, 1500, 2000
ms and Continuous Wave (CW).
NOTE: In CW (Continuous Wave) mode, depending on the thermal load of
the system, the system may shut down prior to the footswitch being
released, with an indication in the LCD display. It is not recommended
to use exposure times longer than 2 seconds in CW mode.
The Power Knob
The Power Knob is used to adjust the treatment laser power and it functions as
described below:
Turning the Power Knob clockwise increases the laser power.
Turning the Power Knob counter-clockwise decreases the power power.
The Power Knob adjusts the power setting to the values shown in Table 2-1.

Doctor Protection Filter Ports
Two ports are provided to connect Doctor's filters. If more than one filter is needed,
both ports can be used at the same time. There is no direct correspondence between
the laser ports and Dr. Filter ports.
If the Doctor Protection Filter is not engaged, the warning message “Please Engage
Dr. Filter” is displayed on the LCD. This message is displayed every time a port
with a slit lamp or endoprobe fiber connected is selected. Acknowledging the prompt
removes the warning message and allows normal operation to continue.
WARNINGS!
The operator may have a colored view through the Doctor Protection Filter due
to blocking of the 532 nm wavelength (green). Newer filters are more transparent
and provide a less-discolored view.
The operator must be careful to avoid potential secondary reflections. Therefore,
the treatment room should be approved by a qualified laser safety officer.
Footswitch Connection
Either a standard footswitch or a multi-function footswitch is connected to the system
through this port. The multi-function footswitch provides additional controls to
change laser power and switch between Standby and Ready modes.
Power Cord Connector and Main Power Switch
The power cable for the system is connected in this module and the power switch is
located above the power connection. If the Emergency Switch is pressed, the power to
the system is shut off even if the Main Power Switch is ON.
8065751131
2.7
Tether Port
This port is used by authorized service personnel to connect a service computer to the
system. A password is required to gain access to the system and this procedure can
only be performed by authorized service personnel.
Remote Interlock Port
The Remote Interlock Connection permits the facility to connect a door activated
switch and/or door warning lamp to the PurePoint™ system (see Section One for
details).
When the Remote Interlock is activated and the connected door is opened:
• when the system is in Standby mode, a message is displayed that prompts the user
to close the door prior to continuing.
• when the system is in Ready mode, the system immediately goes to Standby
mode, and a message is displayed that prompts the user to close the door prior to
continuing.
• when the system is in Firing mode, the laser is turned off, system goes to Standby
mode, and a message is displayed that prompts the user to close the door prior to
continuing.
Laser Status Connector
A lighted warning sign can be mounted at the entrance of the laser room and
connected to the system through this port. When connected, the system will turn the
warning sign on during Ready mode, and turn the sign off during Standby mode. The
port will drive a bulb with a max rating of 24 Vdc, 1A.
FOOTSWITCH
The multi-function footswitch shown in Figure 2-5 has a depressible pedal to fire the
laser and side switches that can be configured via the Footswitch Settings screen to
perform other functions. The footswitch is lit by LED's to make it easy to find in a
dark operating environment.
The side switches, located on the right and left side of the footswitch enclosure, are
either enabled or disabled according to the selection in the Footswitch Settings screen
(see the Footswitch Settings screen
Side Switch (2)
Footpedal
description later in this section of the
manual). When enabled, they can be
configured to control laser power or
the transition between Standby and
Ready modes.
When changing the laser power,
holding a side switch depressed
does not auto-increment or autodecrement. The power value on the
LCD is updated when a side switch is
released. Therefore, each change of
value requires a separate press and
release.

SYSTEM MODES
The PurePoint™ system has three modes describe the different operational states of
the system.
Standby Mode
The system starts in this mode after initialization. It also falls back to this mode in
response to various events. Settings can be adjusted in this mode, but the system
cannot deliver treatment laser energy.
Ready Mode
This mode is initiated when the Standby/Ready button is pushed while the system is
in Standby mode. After the button is pushed, the system pauses for 2 seconds, flashes
the parameters section of the LCD display, then the system transitions into Ready
mode. The system is now prepared to deliver treatment laser energy.
Firing Mode
Pressing the footswitch in Ready mode causes the system to deliver laser treatment
energy.
TREATMENT MODES
The system has three treatment modes that determine how the treatment laser shots
are delivered.
Repeat Mode
In this mode, pressing and holding down the footswitch pedal causes the laser to fire
repeatedly, in a sequence. The individual shots have a duration set by the value in the
Pulse Duration field of the display. The time interval between the shots is set by the
value in the Interval field of the Display. Lifting the footswitch pedal stops the firing
sequence.
Single Shot Mode
In this mode, one treatment shot is delivered per each press of the footswitch pedal.
Continuing to hold down the footswitch pedal in this mode after the treatment shot
has been delivered shall have no effect. The Treatment Shot duration is set by the
value in the Pulse Duration field of the display. Lifting the footswitch pedal stops the
firing sequence.
Continuous Mode
In this mode, pressing and holding down the footswitch pedal causes the laser to fire
continuously as long as the footswitch pedal is depressed. Lifting the footswitch pedal
stops the firing sequence.

RESET TO FACTORY DEFAULTS
Selecting Reset to Factory Defaults from the Main Menu
displays the screen shown Figure 2-25. This screen allows

is prompted with an “Are you sure?” message before the
default settings take effect.
Selecting “Yes” will reset all factory settings to the original
settings and return the user to the Main Menu. “Cancel” will
cancel the operation and return to the Main Menu with the
settings unchanged.
