Preoperative Setup of the Slit Lamp and Laser 71
Selecta
PBL200051, Rev J
WARNING - If the aiming beams cannot be made coincident, do not use the
laser on patients. Doing so may cause inadvertent damage to nontarget tissue
and injury to the patient. Contact your local Lumenis representative.
10 Lock the slit lamp in this position.
11 Select minimum energy settings.
12 Select the Ready mode.
13 Verify that the aiming beams are still converged into a single spot.
14 Depress the joystick pushbutton or the footswitch to activate the laser.
15 Inspect the burn mark through the binoculars. Verify that the burn mark on
the target photographic paper is coincident with the aiming beam spot.
16 Repeat the test as necessary.
WARNING - If the laser burn mark and the aiming beams are not coincident,
do not use the laser on patients as it may cause serious injury. Contact your
local Lumenis representative.
Verify the laser aiming beam accuracy—SLT
WARNING - Verifying the aiming beam is extremely important for the safe
operation of your laser equipment. Do not use the laser if the aiming beam is
not visible. Ensure that it is a clear circular shape, with no part of the beam
missing. Operating the laser without the aiming beam or with a poor aiming
beam may result in laser exposure to nontarget tissue and possible injury.
WARNING - Correct optical alignment is critical for accurate aiming of the
equipment. This pre-operative procedure should be performed daily.
1 Swing the illumination tower to the center position.
2 Tape a piece of laser alignment thermal-sensitive paper (Kentek Zap-It® or
equivalent) onto the slit lamp headrest so that it is visible through the slit lamp
eyepieces. Do not use the slit lamp focus post as a target.
WARNING - Ensure that there are no reflective surfaces behind the paper
mounted on the forehead assembly.
3 Turn on the system as instructed in “Turn on the system” section of this
manual.
