The laser beam emitted by the WON COSJET ATR S laser system is capable of causing loss of
vision. Laser beam energy emitted by this system lies in the visible and invisible, near-infrared
region of the electromagnetic waves.
Remember this and take precautions to avoid inadvertent exposure. The cornea and lens of the
eye are transparent to the invisible 1064 nm wavelength emitted from this laser, and therefore
will focus the beam directly onto the retina. Such direct impingement of the laser beam on the
retina can result in temporary clouded vision, retinal lesions, long-term scotoma (vision absence
in an isolated area), and long-term photophobia (sensitivity to light).
NOTE
Refer to EN 60825-1.
The beam emitted from the Handpiece is expanding with a full-angle beam divergence. This
means that the spot size enlarges as the distance from the Hand-piece. There is a distance from
the Hand-piece, called the NOHD (Nominal Ocular Hazard Distance), at which the beam is so
big that it is no longer dangerous to the unprotected eye.
Personal eye protection: Everyone present in the laser room during a treatment session must wear
laser safety goggles. Laser safety goggles must perform to specifications defined in the technical
data.
To avoid these vision hazards, everyone within the NOHD where the laser system is operating,
including during service procedures, must wear appropriate eye protection. Such safety goggle,
available from WON TECH, provides adequate protection against reflected or scattered laser
radiation, or inadvertent brief exposure to the laser beam. Laser safety goggle should be stored
away from direct sunlight.
The protective goggle recommended for use with this laser system by all personnel is either
goggles or spectacles (with side shields) that have an optical density of 6.0 or greater at 1064 nm
and an optical density of 7.0 or greater at 532 nm.
During laser procedures, the patient’s eyes must be protected. The patient goggles provided by
WON TECH are appropriate for most patients. Even when wearing protective goggle, looking
directly into the path of the laser beam may cause permanent eye damage.
The laser beam emitted by the WON COSJET ATR S laser system should never be directed at
any part of the body other than the intended site of treatment or testing. Care should be taken to
avoid unintended exposure of any part of the patient or other personnel to the laser beam.
Removal of any of the exterior panels of the laser system cabinet could allow access to hazardous
levels of laser radiation. For this reason, these panels are designed not to be easily removable;
they must not be removed except by authorized, trained service engineer.
Optical Safety Precautions
-
Identify the laser room clearly. Post appropriate warning signs in prominent locations at
all entrances to the laser room.
-
Cover all windows, portholes, etc. with opaque material to prevent unintended viewing
or laser light escaping from the laser room.
