Starting Laser Treatment
1.
Turn on the aiming beam, and set it to high intensity.
2.
Test the integrity of the aiming beam.
Hold a non-reflective surface, such as a tongue depressor, in front of
the fiber tip. For side-emission delivery systems, hold the non-
reflective surface in front of the side opening at the fiber tip.
A green spot, the aiming beam, should appear on the surface. If the
aiming beam is weak, check that it is set to high intensity. If the aiming
beam is still weak, verify that the laser debris shield and delivery
system laser connector are not damaged. Refer to “Inspect / Replace
the Debris Shield” and the section in the appropriate delivery system
instruction guide (look under “Inspect the laser connector”).
WARNING:
• Do not use the delivery system if the aiming beam is set to high
intensity and is still weak or not visible; the fiber optic cable may be
damaged. A damaged cable may cause accidental laser exposure or
injury to the treatment room personnel or patient, and/or fire in the
treatment room.
• Do not use the laser or delivery system if the aiming beam has not
been verified. Verifying the aiming beam integrity is extremely
important for the safe operation of your laser equipment.
• Do not use the laser or delivery system if the aiming beam is not
visible. Operating the laser without the aiming beam may result in
laser exposure to non-target tissue and possible injury.
NOTE:
When using the delivery system with an endoscopic camera, lower the
intensity of the camera light if the aiming beam is weak or not visible.
Doing so will not affect visibility at the treatment site, since the camera
compensates for the lower level of light.
3.
Position the aiming beam on the target tissue.
