Early release of the footswitch will terminate the treatment beam before the complete
pattern has been delivered. It is recommended that the pattern be completed by delivering
the burns individually. DO NOT repeat the pattern at the same targeted tissue, as the
pattern will start from the beginning, resulting in overlapping burns.
When a pattern with multiple spots is selected, use caution when operating with a multiple
mirror contact lens. Do not overfill the mirror with the pattern and ensure that you have
visualization of the complete pattern and the area to be treated prior to laser treatment.
Do not use any contact lens with a laser spot magnification of <0.94.
Do not use wide field contact lenses. Wide field lenses will enlarge the spot diameter and
alter the Foveal Exclusion Zone ring diameter.
Selecting the wrong contact lens or entering the incorrect magnification factor for a custom
lens will cause the displayed fluence to be incorrect. Endpoint Management modulates both
Power (mW) and Exposure (ms) simultaneously. When Power reaches the lower limit, only
Exposure is adjusted. If engaging Endpoint Management at or near these minimum power
limits, lower Endpoint Management percentage values may be required.
Do not use the LIO if it has been dropped or if there is visible damage to the housing or fiber
until the LIO has been checked to work properly by certified personnel.
The video monitor must not be used to guide treatment or for diagnosis. The treating
physician must visualize treatment through the slit lamp at all times.
Footswitch marked with IPx1 is suitable for general or office use. Do not use the system with
footswitch in the operating room.
When used in a surgical environment, ensure all concentrations of O2 are low and that
flammables or volatile anesthetics, alcohol and surgical preparation solutions are
decreased. All solution soaked materials must be separately bagged and contained and/or
removed from the room prior to the use of laser (e.g. prepping dispensers, applicators, drip
drapes). This includes items used by the anesthesia providers. The anesthesia provider will
decrease FlO2 (Fraction of inspired oxygen) to minimum amount possible to maintain
adequate SpO2. Be aware of possible enriched O2 and N2O atmospheres near the surgical
site under the drapes, especially during head and neck surgery. Tent drapes to allow
oxygen, which is slightly heavier than air to drain away from the patient’s head and toward
the floor.
If the system becomes unresponsive at any time other than during laser emission, do not
press the emergency laser stop button. Instead, turn the key switch to the OFF position.
Wait at least one minute before restarting the system using the key switch.
If the control panel is blank for more than 60 seconds during system start-up, verify that the
power indicator LED on the front of the control panel is illuminated. If it is not illuminated,
then press the Power button on the right of the control panel to turn on the control panel. If
the control panel remains blank, turn off the system with the key; verify that all control panel
cables are plugged in and fully seated; and then restart the system. If the screen is still
blank, turn off the system and contact service.
