Optical
The laser beam emitted by the POLYLASE LP Pulsed Dual Output Alexandrite and
Nd:YAG Laser is capable of causing loss of vision. The laser operates at 755 nm and
1064 nm, which fall within the near-infrared (IR) light spectrum. The cornea and lens of
the eye are partially transparent to near-IR light; therefore, any energy transmitted by the
POLYLASE LP Pulsed Alexandrite and Nd:YAG Laser that enters the eye will be
focused directly on the retina. Direct absorption of laser energy by the retina can result in
temporary clouded vision, retinal lesions, long-term scotoma (isolated voids in field of
vision), and long-term photophobia (sensitivity to light).
To avoid these vision hazards, everyone in the area where the POLYLASE LP Pulsed
Alexandrite and Nd:YAG Laser is operating or being serviced must wear appropriate eye
protection as described below. All windows in the room where the laser is being used
must be covered with opaque material, and measures should be taken to prevent
unauthorized access to the room. Laser warning signs must be posted at all entrances
wherever the POLYLASE LP Laser is in use. An ANSI approved laser safety sign is
provided with each laser system, and additional signs may be purchased directly from
Customer Support.
All personnel in the treatment room during operation or
service, including the person being treated, shall wear the
appropriate eye protection before starting the system and then
during use. Eye protection should not be removed until the
system is turned off. Note: merely closing your eyes offers
insufficient protection from Alexandrite and Nd:YAG laser
light.
Safety Considerations
•
Identify the laser room clearly, posting appropriate warning signs in prominent
locations.
•
Block all windows, portholes, etc. to prevent laser light from escaping the laser
room.
•
Restrict entry to the laser room when the laser is in use. Allow access to the laser
room only to those personnel both essential to the procedure and well-trained in
laser safety.
•
Make sure that all laser room personnel are familiar with the laser system controls
and know how to shut down the laser system instantly.
•
Appoint one person to be responsible for laser system controls during the
procedure.
