General Safety Precautions (Refer to IEC 825-1 or
ANSI Z136.1)
• A laser safety officer should be appointed to
supervise the installation and use of the system.
SYSTEM INSTALLATION
The system was inspected mechanically and electrically
prior to shipment. If shipping boxes appear damaged, ask
that the carrier’s agent be present when system is
unpacked. Inspect system for external damage (i.e.
scratches, dents, or broken parts). If damage is discovered
or if system fails any of the functional tests notify the
carrier and an Alcon Surgical representative. Retain
shipping boxes and packing material for carrier’s
inspection. As necessary, file a claim with carrier or, if
insured separately, with insurance company.
•
Install an indicator light outside the laser room
warning of instrument operation.
•
Position the instrument so that the laser beam is
never directed toward a door, window or
reflective surface.
•
Use a non-reflective matte finish wall paint.
•
Avoid covering laser room floor and walls with
carpet or any other dust generating material.
This will minimize the possibility of excess
grime and dust on the instrument optics, and
interference with equipment cooling.
•
The instrument requires a minimum of 0.5 meter
of open space on all sides for proper cooling
ventilation. Therefore, the system should be set
flat, resting on the legs provided on the bottom
of the console.
•
Unauthorized use of this laser should be
prevented by key removal.
NOTE: When unpacking a demonstration system, save
boxes for repacking.
General Laser Room Layout
The EyeLite® must be installed in a dust-free room, and
positioned so the laser beam cannot be directed toward a
door, window, mirror, or reflective area. To reduce dust,
avoid installing the instrument in a carpeted room. An
example of a typical laser room layout is shown in Figure
1-2.

SECTION TWO
THEORY OF OPERATION
The purpose of this section is to provide general
information regarding how certain PCB's and circuits
operate and the functions they are responsible to
perform. This section is not intended to provide an indepth, component-level analysis of the system. Voltage
and/or signal analysis can be performed by analyzing the
schematics for the PCB’s manufactured by Alcon.
Theory of operation and schematics for OEM products
used in the EyeLite® remain the property of the
respective manufacturers.
voltage goes through a step down transformer and is
reduced to 20V. This 20V signal is rectified by BR1 and
regulated down to 12VDC. This 12V signal is sent to the
green LED at the rear of the system and is then routed
through the Front Panel PCB to check the status of the
key switch. If the key switch and Emergency switch are
properly set, the 12V signal is sent to energize K1 and
power up the rest of the circuits.
DC Power
The Back Panel PCB receives ±12V and +5V from the
Analog PCB through J6. These signals are processed and
sent out to other PCB's used in the EyeLite. ±12V and
+5V are sent to the CPU (Microprocessor) and Interface
PCB’s through J10. Part of the -12V is regulated down
to -5V (U1) and then sent to the Interface PCB along
with the ±12V and +5V through J10.
Figure 2-1 is a block diagram which shows a simplified
overview of the system. Following this diagram, each
block is discussed in detail with an associated detailed
diagram of the block. Refer to Tables 2-4 through 2-11
at the end of this section for descriptions of PCB
interconnections.
Filtered DC Power
The 5V signal received from the Analog PCB is
amplified by a DC to DC converter to ±12V. This signal
is designated by ±12VA. This ±12V is used to provide a
clean (relatively noise free) ±12 volt signal to the analog
devices of the Interface PCB (J1).
BACK PANEL PCB (see Figure 2-2)
The Back Panel PCB consist of several circuits designed
to provide an interface between the outside devices and
the laser system. A secondary function is to provide
power for certain PCB’s and devices.
Power Entry Module
Power is received via the line source and processed in
the Power Entry Module. The line voltage is then filtered
through L3 and splits at this point. The first part of the
voltage is sent to relay K1. When K1 is energized, it will
send voltage to the power supplies. The other part of the

Interlock
The Interlock circuitry resides on the Analog PCB. The
interlock connection is typically connected to switch
located near a door in such a manner that opening and
closing the door will operate the switch. The wires from
the switch are connected to the interlock plug at pins 2
and 8. With the interlock plug connected and the door
switch closed, the signal from the Analog PCB is pulled
low. This originates from a relay. When the door is
opened or the plug removed, the circuit on the Analog
PCB is pulled high, the laser is disabled, and the
interlock error signal is sent to the Interface PCB.
Doctor's Filter
The Doctor's filter circuit serves two purposes. Pins 1, 3,
and 5 are used to monitor the micro switches of the
Doctor's filter. These signals are routed directly to the
Interface PCB. These signals are designated DRF1_1,
DRF1_3, and DRF1_5. DRF1_CTRL is a buffered 5V
analog signal from the Interface PCB. This signal is
amplified by U4 and sent to Pin 6 however it is not
currently used. There are provisions and circuits for a
second Doctor's filter (U3) included as well, and are not
used at this time.
OTHER CIRCUITS
Footswitch
When the footswitch is depressed, FS_NC is high
(+12V) and indicates to the Interface PCB that the
footswitch is depressed. This +12V comes from the
Optics PCB via J7. FS_NO is pulled low under the same
conditions. When the footswitch is not depressed,
FS_NO is high (+12V) and indicates to the Interface
PCB that the footswitch is connected to the EyeLite.
Laser On
This circuit is used to activate an external warning lamp.
When the EyeLite® is in the Ready mode the LZRDY
signal is used to energize relay K2. When K2 is
energized, power to activate an external relay is
connected.

This signal is generated by the Analog PCB indicating
that the laser is set to fire. It is routed to the Optics PCB
by J7. A low signal indicates that the laser is ready.
POWER DISTRIBUTION (Figure 2-3)
Volume and Message Control
The +5V buffered signal is sent to two potentiometers
via J1 pin 31. R24 controls the message panel display
and R23 controls the volume. The volume function is not
currently used.
The power supply module consists of two switching
power supplies piggy-backed together. The upper supply
is the Electronics Power Supply and supplies the
necessary +12, -12, +5 V to run the circuit boards. Its
output is connected to the Analog PCB.
The lower power supply is the Laser Power Supply
which drives the laser diode and head TEC (thermo
electric cooler). It provides -3.3 V at up to 38 amps for
the laser diode, and 12 V for the TEC. Attached to the
Laser Power Supply is a solid state relay that interrupts
the 120/240 V input when it is determined that the laser
head should be shut off.
The Laser Power Supply has a 5A 250V fuse on the
input and the Electronics Power Supply has a 2A 250V
fuse. Both fuses are of the T20 variety.

INTERFACE PCB (see Figure 2-5)
The Interface PCB receives commands from the CPU
via A2J2, the Synchronous Expansion Bus (SEB). The
SEB signals are tabulated in the CPU/INTERFACE
Table. Address lines A1-A8 and Al2-A15 connect
directly to U1, a Programmable Logic Device (PLD)
which decodes the addresses according to the description
given in the PLD Assignments Table.
Essentially the CPU communicates with the EyeLite® via
the SEB and a serial communication port located on the
Front Panel. The Interface PCB performs Analog to
Digital Conversion of input signals received from the
Analog Board by U7 and U14, 12 bit and 8 bit
converters. Conversely, Digital to Analog conversion of
the commands from the CPU is performed by three 8 bit
converters, U8, U9 and U10. Single bit I/O (Input/
Output) is handled by the two PPI chips, U12 and U13.
These ICs are used to input status, and to output control
signals, primarily to the Analog PCB. Signals to and
from the Optics PCB are handled through the PPI’s.
A serial type I squared C bus is created by bit banging
clock and data signals out of ports PC1 and PC4 of U12.
In this manner, parallel data is converted into a serial bus
stream (much like changing parallel data into serial data
2-6
using a shift register) which is used to communicate with
U23, an on-board EPROM, and U19 an EEPROM type
digital potentiometer chip. Also, communication with
the EEPROM located on the Analog PCB is effected by
this serial bus. These PROMs are used for the
nonvolatile storage of serial numbers and other data.
They do not currently play an active function in the
operation of the Interface PCB.
U3 and U4 are bus driver chips used to isolate the
Interface PCB data bus from the CPU. Data direction is
controlled by direction and control lines connected to the
PLD. A counter timer chip, U5, is used as a safety check
on the laser output control pulse, labeled DIO_CUR and
output from U8. U8 is reset to its low level by triggering
-LDAC6 low at the end of the safety pulse time out.
Interrupts reserved for future use are implemented by the
interrupt controller chip, U2. Also reserved for future
use is the sound chip circuitry consisting of U6, a
Yamaha Digital to Analog Converter which is used to
input serial data to U20. U20 in conjunction with U22
generates analog sound data which is amplified by U21
and U24. U24 is the TDA7052A audio amplifier whose
volume is controlled by the voltage developed across a
potentiometer located on the Back Panel. The
potentiometer signal VOL_CTRL is amplified by U21
and output to the volume control circuit of U24.

EyeLite®/Eyelase green
ANALOG PCB (see Figure 2-6)
The Analog PCB is an OEM product that controls and
monitors all functions of the laser engine (head). It
provides current and temperature controls to the laser
head.
Watchdog
The Watchdog circuit is a mechanism that shuts down
the laser diode driver and the diode power supply unless
it receives the correct signal from the CPU. A 500Hz
TTL square wave generated on the Interface PCB tells
the Watchdog monitor circuit that the EyeLite® is
working properly. Additionally the Watchdog signal is
used as a clock for the Current Fault Detect, and SSR
Time Out. Absence of the Watchdog signal as a clock
will prevent any other circuit from activating the laser.
When this condition occurs the output of U8 goes low
and triggers a fault condition to control PAL U13 and in
turn triggers the SCR to short to ground.
Diode Current Control
The current is controlled through the use of current
sensors, comparator, and target level current setting. The
signal DIO_CUR is received from the CPU via the
Interface PCB. This value is compared with the value of
the current sensor (S1). Any difference is amplified by
U1 and causes the current to increase or decrease.
Light Loop
The Light Loop is an optional tool used to control the
current. A reference voltage is set by the CPU via the
Interface PCB for comparison with the Photocell
(PMON1). With the Light Loop turned on, the diode
current can be adjusted by monitoring the FD_BAK
(feedback) signal and adjusting the REF_LVL (reference
level) voltage up or down. The analog current loop is
added to the output of the Light Loop and is fed to U1 to
control the laser output.
Diode Current Shutoff
The Diode Current Shutoff is a controlled way of turning
the diode current on or off. When Q1 is turned on, the
gate drive of the series pass FETs is pulled down and
thus turning them off.
Over Current Monitor
An overcurrent situation occurs when the current set
point voltage is less than the voltage of the current
sensor S2. When this condition occurs the output of U7
goes low and triggers a fault condition to interlock PAL
U13 and in turn triggers the SCR to short to ground.
2-8
Over Voltage Monitor
The purpose of the Over Voltage Monitor is to protect
the diode in case a failure turns on the current drive
circuitry. A comparison is made between the actual
voltage sensed to the diode and a preset value. If the
actual exceeds the preset at U7, a fault signal is sent to
the PAL U13 and triggers the SCR to short to ground.
Interlock PAL
The Interlock PAL receives the fault signals then
generates the appropriate error codes (LEDs) and takes
appropriate action, mainly shutting down the laser
through the SCR. Through the use of a clock signal and
the latching function of the PAL, changes to the IR
Relay Control are limited to the times when the diode
current is off.
Diode Power Supply Crowbar
This circuit’s primary function is to shut down the laser
immediately in the event of a catastrophic failure. When
a fault signal is received, Q3 turns on which turns on
TH1. TH1 shorts the -3.3V signal from the 300W power
supply to ground. This remains shorted as long as
current is supplied through R43. Soon after the crowbar
circuit is activated, a signal is sent to the Solid State
Relay (SSR) causing it to open, and thus turning off the
300W diode power supply.
SSR Timeout
The SSR (Solid State Relay) located on the power
supply module is controlled by the SSR signal. Upon
power up of the system the SSR is locked out until a
reset signal is sent to Timer U14. When the
microprocessor sends the reset signal, the Timer is
clocked by the Watchdog circuit and the PAL allows the
SSR to turn on.
Head Temperature Control
The laser head uses a Thermo Electric Cooler (TEC) to
maintain proper laser head temperature. This device is
capable of cooling and heating. It is comprised of two
dissimilar materials that, when current is applied to it,
will cause one material to heat and the other to cool. If
the current is reversed, the cooling and heating action is
reversed. A thermistor monitors the head temperature
and provides the control signals to the TEC circuit. If the
temperature is too high, current is sent through the TEC
to provide cooling. Conversely if the temperature is too
low the current it sent to provide heat. When the cooling
function is enabled, LED11 illuminates. Over or under
temperature conditions will cause a fault. Optimal
operating conditions are set by the manufacturer.

Doubler Temperature Control
The doubling crystal temperature is monitored by a
thermistor. Optimal operating conditions are set by the
manufacturer. The output of the thermistor is tied to a
heater that keeps the temperature in its optimum range.
A fault condition (interlock) is sent to the Interface PCB
and then the CPU if the temperature of the doubling
block exceeds its established boundary.
906-5420-501
Fan Speed Control
The Fan Speed Control circuit consists of a comparator/
amplifier circuit and a voltage limiting diode circuit.
Signals from the head temperature control circuit are
analyzed by the CPU and then sent to the fan speed
control circuit. As the temperature increases, the input to
the comparator circuit increases and the output
decreases. A decrease in the output causes an increase in
fan speed. Diodes limit the minimum voltage to the fans
to 12V.

EyeLite®/Eyelase green
LASER HEAD (see Figure 2-7)
NOTE: There are no serviceable parts inside the
Laser Head. It is imperative that no attempts be
made to disassemble the Laser Head.
The Laser Head assembly is a sealed box that contains
the Head PCB, Laser Cavity (YAG Rod, Diode, and
Mirrors), Doubling Crystal, Photocells, and Thermistors.
Head PCB
The Head PCB contains the adjustments for the Diode
Max Current, Head Temperature Set, Doubler
Temperature Set, Photocell monitors (PMON 1 and
PMON 2) and EEPROM. This PCB is part of the Laser
Head and is not replaceable. All adjustments except the
Photocell monitors are preadjusted to match the
performance characteristics of the Head and should not
be changed.
Laser Cavity
The Laser Cavity is hermetically sealed to prevent
contamination. It contains the YAG rod, Photocells,
Diode, and Mirrors. The YAG rod is side pumped by a
diode array. The current controlled diode array controls
the output power. The IR beam resonates between the
mirrors and the doubling crystal. As the IR passes
through the temperature-controlled crystal, the second
harmonic is filtered out and passed through a Green
Output coupler and IR high reflector. This arrangement
is known as Intercavity Doubling. The optic assembly of
the laser head is mounted to a thick plate. Attached to
this plate is a TEC (Thermo Electric Cooler), which in
turn is attached to a large heat sink. When the head
temperature is too high the TEC cooling element is
turned on and transfers the heat to the heat sink.

OPTICS PCB (see Figure 2-8)
The Optics PCB is responsible controlling all of the
components on the Optics block. It receives commands
from the Interface PCB and sends them to the
appropriate component. Additionally, it takes data
(signals) from the various components, processes it, and
then sends the results to the Interface PCB.
Shutter Safety Interlock
The safety interlock circuit routes the +12V through the
footswitch to the shutter motor driver circuit prior to the
footswitch being depressed. This circuit insures the
shutter cannot be opened unless the footswitch is
depressed.
Shutter Motor
The shutter motor drive signal comes from the Interface
PCB. A logic level high is input to an amplifier (U3) to
boost the signal to 5V. A logic low at the input is
amplified to -2V. The +5V signal is used to open the
shutter, the -2 V is used to close it. This signal is routed
to a comparator that checks the signal from the push-pull
circuit. If the LZON signal is low (Laser enabled) the
shutter drive signal is transmitted to the shutter motor. If
the LION signal is high, the shutter drive signal is
blocked.
Shutter Position
The shutter position is detected by an optical interrupter.
With the shutter open the photo transistor conducts and
saturates the transistors. With the transistor saturated the
input to the op amp (U4) is low and drives the output
high. With the shutter closed the collector of the photo
transistor is open and the input to the op amp is high
with respect to Vref and drives the output low.
Fiber Detection
Fiber detection consists of an optical interrupter circuit
and an operational amplifier. A signal is sent to the LED
that illuminates the photo transistor of the optical
interrupter. The collector of the photo transistor is tied to
a comparator circuit (U1) that compares the input with a
reference voltage. When a probe is inserted, the collector
of the photo transistor opens. With an open collector,
output of U1 is high with respect to Vref which drives
the output of the op amp high. When a probe is absent,
the photo transistor saturates and the potential at the
collector is a ground level. With the input at U1 less than
Vref, the op amp is driven low. These signals are sent to
the Interface PCB (J6) for monitoring.

Cell 3 Detection
A photo cell is mounted on the surgical folding mirror
located on the bottom of the optic block to detect the
presence of a laser beam beyond the shutter. The photo
cell is adjusted to the minimum amount of laser beam
emitted at the output of the laser. This signal is filtered
and amplified by U7 and U5 respectively then compared
to Vref at U4. If no signal is detected, the input to U4 is
less than Vref and the output (C3_DET) is driven low. A
logic level high C3_ DET indicates that the laser beam is
detected. If the laser is not firing, a logic level high will
generate an error code.
The Front Panel PCB is responsible for the following:
• Displaying user information and prompting for user
input.
• Displaying system parameters (7 segment LEDs) and
status (LEDs).
• Decoding key switches.
Aiming Beam
The Interface PCB generates the signal Aim SO to
control the Aiming Beam Laser. A high signal shuts off
the laser during firing. A low signal enables the laser.
The intensity is controlled by Aim BP. Built into the
aiming beam module is a 50 µW sensor. This sensor is
used to tell the Interface PCB if the aiming beam laser is
on when power is applied.
Message Display
Messages are received from the CPU through W22. W22
is connected to COM 2 (RS232) and is routed to a
RS232 serial receiver/driver. From here they are sent to
the LCD Message Display Card through W28.
External Speaker
A speaker signal generated on the Interface PCB is
routed through the optics board to the speaker.
Other Circuits
There are three LED's that are used for visual
verification of voltages.
LED 1 = 5 Volts
LED 2 = -12 Volts
LED 3 = +12 Volts
FRONT PANEL PCB (see Figure 2-9)
The functions of the Front Panel are controlled by U8 a
Motorola Microcontroller. This integrated device is
programmed as a key decoder, lamp encoder, frequency
counter, and message display controller.
Key Decoder/Lamp Encoder
U5, U6, and U7 in conjunction with U8 form a
multiplexed keypad switch and LED matrix. These
signals are input to the Display PCB. The Display PCB
monitors keypad strokes and sends information to the
microcontroller. Depending on the function, the CPU
will return a signal to illuminate the appropriate status
LED.
Frequency counter
The aiming potentiometer is attached to a Variable
frequency oscillator (U16). As the aiming potentiometer
is adjusted, the pulse width of the oscillator changes. The
microcontroller (U8) sends this data to the CPU PCB for
further processing.
Other Functions
Contrast Controls
The signal from the Back Panel PCB Illumination Pot is
routed to the Display PCB via the Interface PCB and the
Front Panel PCB. This signal is passed to the display
assembly and controls the contrast of the LCD
characters.
Timer Display Card
The Timer Display Card receives the multiplexed signals
DS1-4 and the driver signals A-G and uses them to
display the selected exposure time on four 7 segment
LED’s.

LASER ENGINE INSPECTION
WARNING!
Laser light emitted from the fiber and laser head is
powerful enough to cause serious eye or skin
damage. Maintenance should be performed only
by properly trained personnel, following
established guidelines for laser safety. The use of
protective eye wear is mandatory.
1.1
Connect computer terminal to the service port on
the EyeLite® rear panel. Turn on the computer and
start the communications software. Refer to the
Special Tools section for communications protocol.
906-5420-501
• If an "Off Condition" or "Power Out of Range"
message appears, calibrate the system, and repeat
steps 1.1 - 1.8. If condition persists, proceed to step
1.9.
• If no errors appear, increase power by 100 mW and
repeat step 1.8 for each setting until 1.7 W is
reached. If no errors appear, repeat steps 1.1 - 1.6,
enter the correct value for efficiency and proceed to
step 4.
1.9
Change exposure time to 0.100 seconds and select
repeat mode. Change the inter-pulse time to 100ms
and increase the power setting to 500 mW.
1.10 Place the unit in ready mode. Press the footswitch and
fire the laser for a minimum of 50 shots. While firing
the unit, observe the power meter. Record the
maximum value. This value should be at least 50% of
the requested power setting.
NOTE: If an OFF condition or Power out of Range
message appears, lower the requested value and repeat.
Keep lowering the requested power until the laser will
fire without an error.
• If the desired output is not obtained, the Laser Head
may require replacement. Turn off the laser and
proceed to step 2.
• If the desired laser power is obtained (or reasonably
close), Increase power by 100 mW and repeat step
1.10 for each setting until 1.7 W is reached. If no
errors appear, proceed to step 4 to test the fiber
alignment.

TROUBLESHOOTING
The following tables and troubleshooting trees are
provided as an aid to troubleshooting the system. The
flow of the troubleshooting trees is left to right and top to
bottom. For example: the system displays a "Footswitch
Fault" which is described in Table 4-2, item 1. This table
refers to Figure 4-27 for corrective action. Starting at the
box on the left side of the tree, follow the branch down
until the problem is corrected or it is determined that this
branch does not contain the appropriate corrective action.
If it does not, proceed to the next branch on the right and
continue in this manner until the problem is corrected.

General Troubleshooting
SYMPTOM
PROBABLE CAUSE
CORRECTIVE ACTION
EyeLite¨ does not start and
displays 0's in the power and
exposure time displays.
CPU/Software did not boot.
Defective CPU or PCMCIA
card
Replace CPU and/or PCMCIA card.
Message display reverts
back to "Confirm Slit Lamp?"
after firing a shot.
Chimney is not correctly
aligned to the fiber optic
cable.
Perform Fiber Alignment (step 4 of the Optical
Alignment procedure).
Fiber efficiency is greater
than what the calibration
routine allows.
Achromat lens in chimney is
not adjusted correctly.
1) Remove chimney from optic block.
2) Rotate barrel nut 1/4 turn clockwise.
3) Replace chimney and test efficiency.
Fiber efficiency is lower than
specification.
Bad fiber
or
Achromat lens in
chimney is not
adjusted correctly.
1) Check efficiency with a good fiber. If OK, then
replace fiber. If not, continue to next step.
2) Perform Fiber Alignment (step 4 of the Optical
Alignment procedure). If efficiency is still lower
than specification, go to next step.
3) Remove chimney from optic block.
4) Rotate barrel nut 1/4 turn counterclockwise.
5) Replace chimney and test efficiency.
6) If condition persists, repeat from step 3 and
turn barrel nut 1/2 turn clockwise.
Hardware Error 05
Additional warm-up
time needed.
1) If laser starts normally after turning the unit off
and back on two or three times, upgrade the
software version to 1.10 or greater.
2) If the problem persists, see Figure 4-41.

SECTION SEVEN
ADDITIONAL INFORMATION
This section of the manual contains service information
for the various accessories that are available for use with
the EyeLite®
SLIT LAMP ADAPTATIONS
A slit lamp assembly is typically used to deliver the
EyeLite® laser treatment beam to the patient. An
adaptation, mounted on the slit lamp, is required to
interface the slit lamp to the EyeLite®.
ALCON SL1000 AND ZEISS** 30SL
SLIT LAMP ADAPTATIONS
This section of the manual covers installation of the
adaptation on the Alcon SL1000 and the Zeiss** 30SL slit
lamps, and a general procedure for aligning the slits and
zoom assemblies.
The Alcon SL1000 and Zeiss** 30SL slit lamps are
shown in Figures 7-1 and 7-2 respectively. Adaptation
components are shown in dark gray.
The adaptation consists of a slit generator, zoom
assembly with micromanipulator, and a doctor’s filter.
The slit generator projects a light beam that illuminates
the eye for clear viewing, and helps the doctor accurately
locate the focal plane. The parfocal zoom assembly is
used to set the spot size of the aiming and treatment
beams, and a micromanipulator is provided for fine
adjustment of the beams' position. The doctor’s filter
provides eye protection for the physician.

ZEISS** ADAPTATION ALIGNMENTS
All instruments are adjusted at time of manufacture, and
should not normally require any adjustment after
installation. The following procedure may be used to test
the system for proper alignment, and make the proper
focal adjustments if needed.
1
Slits Alignment
1.1
For ALCON SL1000: Install calibration rod. Go
to step 1.5.
For ZEISS** 30SL: Place a target (small square
of plastic with millimeter grid graph paper) at
the patient’s chin rest in a vertical position.
(Tilting the target slightly toward or away from
the microscope will accentuate the slits
movement and facilitate the alignment process).
1.2
Turn slit lamp ON. Set magnification to its
lowest setting. Set slit/circle knob to the slits
position. Set horizontal/vertical slits knob to the
vertical position.
1.4
Refer to Figure 7-3. While viewing through
oculars, use the joystick to move the lamp
slowly from back to front, while also swinging
the slits housing left and right. Locate the point
at which the vertical slits pivot about through the
center, as shown in Figure 7-3c. Tighten the
brake thumbscrew to hold the lamp in place.
1.5
Set horizontal/vertical slits knob to the
horizontal position. The horizontal slits should
overlap, and should be centered in the field of
view. If not, adjust the setscrews on both the
upper and lower mirror mount to bring the slits
together, in both horizontal and vertical
orientations, and centered in the field of view.
Figures 7-4 and 7-5 show the location of the
adjustment setscrews.
1.6
Figure 7-3a
Focal Point In Front Of Target/Calibration Rod
Figure 7-3b
Focal Point Behind Target
For Alcon SL1000 only: Check that slit edges
are in sharp focus. If not, loosen slit focus
adjustment screw and position as necessary to
attain sharp focus.

Microscope Focus
2.1
Set your accommodation on both the right and
left oculars, and verify both oculars are pressed
all the way into the holder assembly.
2.2
Set microscope to the highest magnification. Set
the slits to the horizontal orientation, then open
them to a full circle.
2.3
While viewing through oculars, use the joystick
to move the slit lamp back and forth, to reach the
point of sharpest focus on the target. Lock the
lamp in place with the brake knob.
2.4
Narrow the slits down to fine horizontal lines. If
the microscope is properly focused, the lines
should be exactly together (assuming the slits
were properly aligned in the previous steps). If
so, proceed to step 3. If not, the microscope will
require a focusing adjustment.
2.5
Temporarily remove the zoom/micromanipulator
assembly from microscope, to gain access to the
front microscope mounting screw.
2.6
Refer to Figure 7-6. Rotate the slits to the
vertical orientation. With slit lamp locked at
focal point, loosen the two mounting screws at
bottom of microscope head. Move the scope
body fore and aft to obtain the sharpest possible
focus. At the same time, pivot the scope as
needed to center the slits in the field of view.
Tighten the mounting bolts, and retest per step
2.4. Replace the zoom assembly onto the
microscope when complete.

Zoom Adjustments
3.2
Adjust 50 Micron Spot
The zoom adjustment consists of fiber
orientation, 1000 micron spot, 50 micron spot,
and spot convergence. Fiber orientation and spot
convergence adjustments are interactive.
3.2.1
Set the slits to the horizontal orientation, then
narrow them down until they completely
disappear. Set the spot size to 50 micron. While
viewing the aiming spot through oculars, use the
joystick to move slit lamp back and forth, to
reach the point where the spot is the smallest.
Lock the lamp in place with the brake knob.
3.2.2
Open the slits slightly. If the 50 micron spot is
properly focused, the lines should be exactly
together, indicating lamp is positioned at focal
plane (assuming the slits were properly aligned
in the previous steps 1.0 - 1.5.) If so, proceed to
step 3.3. If not, the 50 micron spot will require a
focusing adjustment.
3.2.3
Set spot size adjusting lever to 50. Loosen the
two 50 micron locking setscrews, and make a
small adjustment of the 50 micron focusing lens
inside zoom tower. Retest beginning at step
3.2.1. Continue adjustments until the smallest 50
micron spot coincides exactly with the slits focal
point. Tighten setscrews when complete.

duration, and set power to 0.10 watts on the
front panel. Set the brightness of the aiming
beam as desired for comfortable viewing
through the microscope.
3.3
3.1.2
Set slits to the horizontal orientation. While
viewing through oculars, use joystick to move
slit lamp back and forth to point where slits
come together. Lock slit lamp in place with
brake knob.
3.3.1
3.1.3
Refer to Figure 7-7. Set spot size adjusting lever
to 1000 micron. Loosen the two fiber barrel
setscrews. While viewing through oculars, slide
fiber barrel connector up and down to obtain
sharpest possible spot. Tighten setscrews when
complete.
Each laser fiber is slightly different, so it is
necessary to adjust fiber orientation as it enters
the zoom to ensure the beam travels through the
optical center of the zoom elements.
Refer to Figure 7-8. Using the joystick, move
slit assembly to side and fire laser on a nearby
wall. Adjust the four fiber tilt screws at top of
zoom, to adjust tilt of fiber until spot on wall is
perfectly round without clipping. This
adjustment can be facilitated by observing
centering of the spot on the micromanipulator
mirror.

3.4.1
Use the joystick to position aiming spot on
target graph paper, so spot is centered over an
intersecting pair of grid lines, as shown in Figure
7-9.
4.1
Set the slits to the vertical orientation. Set spot
size to 50 microns.
4.2
Viewing through oculars, observe positions of
aiming spot and slits (see Figure 7-10). If not in
alignment, the aiming spot must be moved
horizontally to overlap the slits.
3.4.2
3.4.3
While viewing through oculars, run spot size
selector through complete range, from 50 to
1000 micron and back. The spot should remain
centered on grid lines throughout range of spot
sizes. If so, spot convergence is correct. Proceed
to step 4.
Set spot size to 50 micron, and use joystick as
needed to center spot exactly over intersecting
grid lines on the target graph paper. Note exact
position of spot, then change spot size to 1000
micron. Slightly loosen the three spot
convergence allen screws on top of zoom flange
and shift flange to bring 1000 micron spot back
to previous position of the 50 micron spot.
Tighten three spot convergence allen screws, and
retest beginning at step 3.4.1.
To move aiming spot horizontally over slits,
adjust and tighten set screws on the right and left
sides of micromanipulator until spot and slits
are aligned (see Figure 7-11).
4.3
Set the slits to the horizontal orientation.
Viewing through oculars, observe positions of
aiming spot and slits. If not in alignment, aiming
spot must be moved vertically over slits.
To move aiming spot vertically over slits, loosen
locking setscrew on side of micromanipulator
and adjust screw on bottom of micromanipulator
until spot and slits are aligned. Tighten the
locking setscrew when complete.

OPERATING PRINCIPLE
KEELER LASER INDIRECT
OPHTHALMOSCOPE (LIO)
The Laser Indirect Ophthalmoscope (LIO) is designed
for use with the EyeLite®, and is composed of an
illumination box and headpiece (see Figure 7-26). The
treatment laser beam and aiming beam are both provided
to the LIO from the EyeLite®. The laser beam power
output depends on the laser source, and can be between
0.05 W and 2.0 W.
CAUTIONS
The LIO is connected to the EyeLite® with a fiber optic
cable. This fiber optic cable delivers the treatment and
aiming beams. Another fiber optic cable delivers white
light from an illumination box. White light intensity is
adjustable from approximately 1000 lux to 3000 lux.
The treatment laser beam, aiming beam, and illumination
are made coaxial with a set of mirrors on the headpiece.
A doctor’s filter protects the surgeon against incidental
laser beam reflections.
The LIO for the EyeLite® is factory configured for a
single primary input voltage of either 110 V or 220 V.
Changing from 110 V to 220 V (or conversely) is only
possible by changing transformer inside instrument.
This change shall only be performed by an
authorized Alcon service technician.
Prior to connecting instrument to primary power
supply, verify voltage indicated on instrument rear
panel, under main power plug, is same as primary
input voltage.
Check that LIO has the inscription “532 nM.”
WARNING!
All staff in operating room must wear protective
goggles, with a minimum optical density O.D. 4.0
(diffused viewing only) and O.D. 5.0 (maintenance
and service) to filter 532nm and 1064 nm laser
light.
FIBER CONNECTION
Connection of the LIO to the EyeLite® does not require
any adjustment to the laser itself and can therefore be
performed by the operator.
The laser fiber exiting the LIO headpiece must be
connected to the EyeLite® terminal output and the LIO
terminal selection must be made.

The Alcon Laser Indirect Opthalmoscope
The LIO is connected to the EyeLite® via a fiber optic
cable. The LIO headset Illuminator is powered by either
a standard desktop power supply or an optional portable
battery operated power supply. Prior to connecting the
primary power supply, ensure the voltage indicated on
the power supply label is the same as the main power
outlet. The illumination light is adjustable from
approximately 0 to 1000 lux (500 lux for portable) using
the illumination control knob on the power supply.
A permanent doctor’s filter protects the surgeon against
incidental laser beam reflections. The operator will have
a colored view through the doctor’s filter due to blocking
of the 532 nm wavelength (green).

ALCON LIO MAINTENANCE
This section of the manual is designed to inform the
operator of basic care and maintenance of the
instrument. If a problem occurs on the instrument, call
the Alcon Technical Services department and give details
of the breakdown circumstances and effects. From these
elements, a technician will evaluate the problem and
determine the maintenance requirements.
WARNING!
Maintenance on any part of the laser system must
be performed with the laser off and the main
power plug disconnected.
Checking the System Appearance
The condition of the system hardware components must
be checked periodically to identify any fault which
might cause incorrect operation of the system.
• Chassis appearance
• Operation of controls and indicators
• State of the fibers and connecting cables
• Check permanent Doctor’s filter for damages or
scratches
Any damaged hardware must be replaced. Contact your
Alcon Technical Service representative.
Mirror and Lens Cleaning
The mirrors and lenses of the LIO headpiece must be
kept clean and unscratched. Cleaning them requires
special care and the following materials:
• Standard lens cleaning paper
• Methanol of spectrographic quality.
7-20
The following tips will aid you in cleaning the optics:
• Use each piece of cleaning paper only once.
• Move the cleaning paper across the optic surface
from one end to the other in one continuous motion.
Discard the cleaning paper and use a new piece for
the next cleaning pass.
• Do not use a back and forth rubbing motion on the
optic surface.
CAUTION
Care and cleaning operations must be performed
with the instrument turned off and power
disconnected. Use only optical quality paper and
spectroscopic quality methanol when cleaning the
mirrors and lenses, otherwise the optics could be
scratched and their coatings destroyed.
Headset care and maintenance
• The eyepieces and the glass in front of the binocular
assembly can be cleaned with a soft cloth (dipped in
alcohol if necessary).
• The cushions for forehead, and nape can be removed
for wiping with soapy water.
• The rest of the instrument can be cleaned with a soft
cloth dipped in alcohol. Under no circumstances
should cleaning fluids be used.

2
Place grid paper 300 mm from the reflecting
mirror as shown in figure 7-30.
3
Adjust the fiber chimney up and down to obtain
1 mm size spot at 300 mm. The diameter of the
spot must be between 850 and 1150 µm at 300
mm. Secure chimney movement by tightening
the three set screws in the LIO body.
4
Turn the illumination beam on and set the
illumination spot size to the medium size. Set
the illumination spot to the middle of its travel.
5
Adjust the position of the grid paper until the
illumination spot is approximately 30mm. Use
target to set laser spot. Verify that the aiming
beam is centered in the horizontal direction of
the illumination spot. If not, use the three
setscrews to adjust/center the aiming beam
within the illumination spot (see Figure 7-31).

Look through the microscope and adjust the
aiming beam as follows until it is in the center of
the field of view and concentric to slit image:
6.1
Adjust the beam vertically by turning the
vertical adjusting screw (11, Figure 7-44). If
turning counterclockwise, depress the area
around the screw slightly to make sure that the
aiming beam moves downwards.
6.2
Adjust the beam horizontally by turning the
horizontal adjusting screws (9) in opposite
directions.
6.3
Lock the link by tightening both adjusting
screws (9) simultaneously.
6.4
After locking the link, check the aiming beam
position again. If it moved, loosen the horizontal
adjustment screws (9) and repeat the procedure
from step 6.1
7
Remove focus rod from slit lamp.

If the spot moves out while turning the Variooptics through the full range of spot sizes,
evenly tighten the three screws beside the SMA
connector until the laser beam transmits the
50µm spot through focusing lens concentrically
(see Figure 7-48).
