2.2 8065751131LCD ScreenThe 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 ﬁ red, "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.Laser Ports 1 and 2Dual 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 Identiﬁ cation (RFID) reader that can identify Alcon RFID enabled probes and automatically set up the default power and time parameters for the speciﬁ c probe. Laser ﬁ bers without RFID must be identiﬁ ed by the operator when prompted on the display.Port Illumination RingThe 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 unidentiﬁ ed 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: BLUEIf no probe is connected to a port, the Port Illumination Ring is illuminated in the color blue.Selected Port Illumination Color: GREENIf an identiﬁ ed probe is inserted into the port and the port is selected, the Port Illumination Ring is illuminated in the color green.Unidentiﬁ ed Probe Indication Color: ORANGEIf a probe is inserted into the port and is unidentiﬁ able by the system, the Port Illumination Ring is illuminated in the color orange, indicating that the probe must be identiﬁ ed before it can be used. Figure 2-2Typical PurePoint®PurePoint®PurePointScreen

8065751131 2.3A 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 identiﬁ ed the probe:• The Port Illumination Ring is illuminated in the color green if the port is the only port with an identiﬁ ed probe. • The Port Illumination Ring is not lighted if the other port already contains an identiﬁ ed probe. The port with the newly-identiﬁ ed probe is not the selected port. The Port Selection Button must be pushed for the probe to be selected.Disabled Port Indication Color: REDIf 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 ButtonsWhen each port has an identiﬁ ed probe, pressing one of the Port Selection Buttons selects the associated port. The Port Selection Buttons are active only when there are identiﬁ ed probes in each port. In all other cases (such as an unidentiﬁ ed probe in one port, only one port being used, no identiﬁ ed 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 ﬁ rst time after starting the system with an identiﬁ ed endoprobe or slit lamp attachment, a screen is displayed asking the user to conﬁ rm that the Dr. Filter is in place.Emergency SwitchPressing 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.KeyswitchThe 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.Figure 2-3Unidentiﬁ able Probe Selection Screen

2.4 8065751131LIO Illumination Power KnobThe 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 ﬁ ber 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 KnobThe 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 KnobThe Menu knob allows the user to highlight and select a menu item shown on the display. The knob rotates to move the highlighted ﬁ eld on the display, and the highlighted item is selected by pressing the knob. Turning the Menu knob clockwise moves the highlighted ﬁ eld to the right (or down).Turning the Menu knob counter-clockwise moves the highlighted ﬁ eld 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 modiﬁ ed, 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 2.5Standby/Ready ButtonThe 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 ﬂ ashes between gray and green for the 2 seconds. During those same 2 seconds, the Standby LED turns off, and the Ready LED ﬂ ashes 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 disconnectedNo identiﬁ ed probe connectedRemote interlock openTethered Dr. Filter disengagedThe LCD is displaying a menu screenPressing the Standby/Ready button while the system is in Ready mode, immediately returns the system to Standby mode.The Interval Time KnobThe 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 steps100 ms to 300 ms in 50 ms steps300 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.••••••••••••••••

2.6 8065751131The Pulse Duration KnobThe 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 KnobThe 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.Table 2-1 532 Green Laser Power Values (in milliwatts)30 40 50 60 70 80 90 100 110 120 130 140150 160 170 180 190 200 220 240 250 260 280 300320 340 350 360 380 400 420 440 450 460 480 500550 600 650 700 750 800 850 900 950 1000 1100 12001300 1400 1500 1600 1700 1800 1900 2000NOTE: The PurePoint™ laser determines the 532 green laser maximum available power and limits the user setting to that maximum value if less than 2 W. The maximum selectable power may be less than 2 W (2000 mW) because of the degradation of the laser engine over time.•••••

8065751131 2.7REAR PANEL DESCRIPTIONFigure 2-4 The PurePoint™ Laser Rear PanelDoctor Protection Filter PortsTwo ports are provided to connect Doctor's ﬁ lters. If more than one ﬁ lter 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 ﬁ ber 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 ConnectionEither 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 SwitchThe 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.

2.8 8065751131Tether PortThis 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 PortThe 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 ConnectorA 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.FOOTSWITCHThe multi-function footswitch shown in Figure 2-5 has a depressible pedal to ﬁ re the laser and side switches that can be conﬁ gured via the Footswitch Settings screen to perform other functions. The footswitch is lit by LED's to make it easy to ﬁ nd 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 description later in this section of the manual). When enabled, they can be conﬁ gured 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 auto-decrement. 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.•••Figure 2-5 PurePoint™ Multi-Function FootswitchSide Switch (2) Footpedal

8065751131 2.9SYSTEM MODESThe PurePoint™ system has three modes describe the different operational states of the system. Standby ModeThe 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 ModeThis 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, ﬂ ashes 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 ModePressing the footswitch in Ready mode causes the system to deliver laser treatment energy. TREATMENT MODESThe system has three treatment modes that determine how the treatment laser shots are delivered. Repeat ModeIn this mode, pressing and holding down the footswitch pedal causes the laser to ﬁ re repeatedly, in a sequence. The individual shots have a duration set by the value in the Pulse Duration ﬁ eld of the display. The time interval between the shots is set by the value in the Interval ﬁ eld of the Display. Lifting the footswitch pedal stops the ﬁ ring sequence.Single Shot ModeIn 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 ﬁ eld of the display. Lifting the footswitch pedal stops the ﬁ ring sequence.Continuous ModeIn this mode, pressing and holding down the footswitch pedal causes the laser to ﬁ re continuously as long as the footswitch pedal is depressed. Lifting the footswitch pedal stops the ﬁ ring sequence.
