Operation and Maintenance.

LightLas 532 –Operator's Manual Rev. No 01 Page 10 of 115
Section 2 SAFETY
This Laser system has been designed and tested to function in a safe and correct
when used as indicated in this manual.
Do not use this laser before reading and understanding completely this Operators
Manual.
It is important to remember that this laser emits high levels of visible laser radiation
which can cause permanent and irreparable eye and tissue damage. Always observe
precautions for laser safety including using warning signs, safety glasses and only
operating the laser in a treatment room that provides protection to casual observers.
2.1 Product Classifications
The LightLas 532 Photocoagulator Laser is a Class IV laser product as specified in the
standard IEC60825-1 (2007) and the USA 21 CFR’s 1040.10, 1040.11.
The LightLas 532 Photocoagulator Laser is classified as Class I Type B Electromedical
equipment as specified in the IEC60601-1 standard.
The LightLas 532 Photocoagulator Laser is classified as a Class II device according to
the FDA CFR21 regulations.
The LightLas 532 Photocoagulator Laser is classified as a Class II Type B Medical
Device according to the MDD 93/42/EEC (as amended by 2007/47/EC).
The LightLas 532 has been designed to comply with the following standards:
Laser standards
IEC 60825-1 (2007)

2.2 Warnings and Precautions
The following warnings and precautions apply to the LightLas 532 Laser System and
should be observed by all users at all time:
DO NOT look directly into the laser beam or at laser reflections since direct
and reflected laser light from the laser aperture can cause permanent eye
injury.
DO NOT operate the laser unless observers are using the correct protective
eyewear. The protective eyewear must have an optical density of OD4 or
more at 532 nanometers wavelength. This information must be present on
the eyewear.
DO NOT use objects that can readily reflect light in the vicinity of the laser
beam to avoid reflecting the beam in a hazardous manner.
DO NOT fire the Laser directly onto flammable agents or gasses as the
focused laser beam may cause ignition. There is no AP/ APG protection.
DO NOT try to service or repair the laser other than what is included in this
manual. Service should only be performed by an authorized and trained
agent of the manufacturer.
DO NOT fire the laser on a patient without first checking the operation of the
laser and verifying the optical alignment of the treatment Laser beam.
ALWAYS use the lowest power settings possible when treating a patient
with the laser and start the treatment with minimum level of power.
ALWAYS set the correct spot size and/or use the most appropriate one for
the power setting and type of procedure that is to be performed.
DO NOT put the laser into ‘TREAT’mode until ready to operate on the
patient.
DO NOT inhale any laser plume generated by the Laser during surgery.
Personnel should take an extreme measured precaution, such as wearing
surgical masks or use plume evacuation systems when a treatment is
undergoing. Caution - Laser plume may contain viable tissue particulates.
ALWAYS take particular care of the optical fibers that connect the Laser
Delivery Units to the Console to make sure they do not get damaged.

LightLas 532 –Operator's Manual Rev. No 01 Page 12 of 115
Additional clinical warnings may be found in Section 6.1.4 of this Manual.
ALWAYS try to let the laser have its own or dedicated power outlet.
Additional items may be plugged in a Multiple Portable Socket Outlet, which
may be plugged into an additional outlet.
DO NOT use the Laser Console if the ambient temperature is outside the
range of 20 to 35°C. This temperature range is the rated operating
temperature limits where the Laser system can be guaranteed to operate
without any interruptions to normal use. Outside this range of temperature
it is possible that the Laser will generate an error condition where the word
“hold” is displayed and the system goes to Standby until the internal
temperature returns to within normal limits then the Laser can be used again
but the error condition may reoccur unless the rated temperature comes
within limits.
2.3 Optical Hazards
Guidance for the safe use of Lasers and Laser systems is found in the standard
IEC60825-1, the USA 21CFR 1040.10, 1040.11 and ANSI Z136.1 - 1986.
During normal operation of the LightLas 532 the operator is protected from Laser
hazards by built in optical absorption Safety Filters. All other personnel in the area
should wear protective eyewear to eliminate the risk of eye injury occurring.
The optical density (OD) of eye protection must be greater than or equal to 4 and the
wavelength 532nm range is also specified on it. It is shown in the following format:
OD4+ @ 532nm
Otherwise, the safety glasses are NOT suitable for this purpose of eye protection.
Safety Glasses are required to have the CE mark applied if used in the EU.
The LightLas 532 uses a Class II Laser Diode Aiming beam. Its wavelength range from
635 to 650 nanometers (nm) and the maximum power output is set at the factory to
be less than 1mW delivered to the patients cornea. However it is always
recommended to use the lowest aiming beam intensity during treatments.
The LightLas 532 Photocoagulator Laser has been classified as a Class 4 and its
classification specified accordingly to the above quoted standards. This classification
is also based on the Accessible Emission Limits (AEL) as calculated according to the
standards.
2.3.1 Nominal Ocular Hazard Distance (NOHD)
The Nominal Ocular Hazard Distance (NOHD) is the distance between the equipment

LightLas 532 –Operator's Manual Rev. No 01 Page 13 of 115
and a person’s eye for which the optical power, from the equipment, entering the
dilated pupil of the person will be less than or equal to the Maximum Permissible
Exposure (MPE) as specified in the standards (i.e. less than a Class 1 Laser Output).
The calculated NOHD for the LightLas 532 with different Laser Delivery Units is:
5 meters at maximum power settings for the Endoprobes
18 meters at maximum power settings and 1000m spot size for Slitlamp Delivery
Units
20 meters at maximum power settings for LIO
Therefore when the laser is in operation, all persons that are closer than these
distances to the equipment should be wearing eye protection.
Patients, where possible, should have the untreated eye covered or protected from
laser reflections.
2.3.2 Avoid Exposure to Laser beams
Reassembly or maintenance of the laser system should only be performed by
authorized and trained personnel. The external housing of the laser system should
never be removed otherwise you or standby observers could be exposed to
dangerous levels of laser radiation and potentially lethal electrical voltages.
Eye safety filters are designed to protect physician’s eyes from back scattered laser
beams must always be used. They are integrated into the Slitlamp and LIO Delivery
Units. When using the endoprobes a separate filter that attaches to the operating
microscope must be used.
For other personnel that may be exposed to reflections or backscatter they must
wear safety glasses or goggles. In any case NEVER look directly at the treatment
laser beam as severe eye injury is likely. This means avoid looking into the aperture of
any of the laser delivery units or the console.
2.4 Electrical Hazards
The Lightlas 532 Photocoagulator laser has been designed to apply the International
Standards for Medical Equipment. The laser system is designed to operate with three
terminal prongs AC voltage where the third prong pin is the earth-grounded prong.
Warning: It is not safe to operate the Lightlas 532 photocoagulator laser without an
earth-grounded receptacle. There is possible risk of electric shock.
No cover or housing need to be removed by the operator or user. Only the
authorized and trained service or agent can remove the cover or housing assembly

LightLas 532 –Operator's Manual Rev. No 01 Page 14 of 115
since there is possible of exposing laser radiation and high current or voltages.
2.5 Product Labeling
All the labels on the LightLas 532 comply with the requirements of the various
regulatory standards referred to previously.
