Usage Precautions (During Use)
• Use of this device other than specified in the instructions contained in this
Operators Manual may result in hazardous exposure to laser radiation.
• To prevent accidental laser exposure, never look directly at the aiming beam
emitted from the laser aperture or point the aiming beam towards others.
• When the treatment beam (520nm) is applied to tissue, the following
symptoms may occur:
o Ocular symptoms: Damage to the cornea, sclera, lens, anterior or
posterior structures causing permanent, partial or temporary blindness
o Skin symptoms: Pain, burns
• If any system errors are encountered, stop treatment and follow system
instructions or call Norlase technical support or an authorized distributor.
• If any adverse events are encountered, they must be reported to the proper
regulatory authorities.
• The user is responsible for ensuring the appropriate safeguards are in place
to prevent unauthorized access into the Norlase laser or user interface.
• Confirm that no reflective objects are in the laser beam path.
• If the user encounters green laser flashback through the slit lamp oculars,
stop treatment and check the integrity of the laser eye safety filters before
proceeding. If there is any doubt as to the integrity of the safety filters, do not
use the device and call Norlase technical support or an authorized distributor.
o It is normal to see orange/yellow fluorescence from the target site,
especially when using high power levels.
• Each procedure should start with titration and slowly increasing the power
level until the desired effect is obtained.
• At the end of each treatment, the “END” button should be pressed to return
the system to Standby and reset to default parameters.
• Laser lenses have magnification factors that manipulate the delivered laser
spot size by either increasing or decreasing the diameter from the user
interface setpoint. Please consider the laser lens magnification when adjusting
power levels.
