Slit Lamp Basics
Slit lamp positioning and joystick control
The slit lamp is mounted to the table and allows for gross positioning of the
slit lamp. Loosen or tighten the instrument base locking screw, as shown in
the following illustration, to move the slit lamp and to adjust the friction
between the base and the table top. The slit lamp position can be locked by
tightening the instrument base locking screw.
The joystick controls lateral, longitudinal, and vertical positioning of the slit
lamp. Moving the joystick moves the instrument in the corresponding
direction. Turning the joystick clockwise raises the slit lamp microscope;
turning it counter-clockwise lowers it.
The position of the laser aiming and treatment beams is fixed in the system.
Therefore, moving the joystick to position the slit lamp, correspondingly
adjusts the position of the laser aiming and treatment beams. The joystick also
has a laser pushbutton which can be used to activate the laser treatment beam.
The laser may be activated by either a footswitch or by the joystick laser
pushbutton. The method of laser activation is user selectable via the
footswitch/joystick mode button on the remote control options screen. For
safety, the laser enables only the selected mode, and automatically disables the
other.
Forcing the joystick to move after the slit lamp base has been locked may
damage the instrument.
Slit lamp controls
CAUTION - During use, beware of hot surfaces on the slit lamp illumination
tower.
As shown in the following illustration and described in the following section,
the Selecta slit lamp has all of the standard diagnostic slit lamp controls such
as illumination intensity, illumination aperture, slit width adjustment and
rotation, as well as the typical diagnostic slit lamp adjustments, such as diopter
eyepiece adjustments, magnification, binocular focus, and interpupillary
distance adjustment. In addition, as an integrated laser slit lamp, the Selecta
also has controls that are specific to operation of the laser. The laser controls
that are located on the slit lamp itself are: the joystick laser activation button,
the energy adjustment knob, the posterior YAG offset control, and the aiming
beam intensity control. All other laser functions are located on the remote
control module.
