3.0 Slit Lamp Adapter (SLA) Installation
3.1 Haag-Streit Slit Lamp Adapter (SLAh)
Y Warning! When changing delivery systems, be sure to place the protective cap on the fiber input.
Debris collected on the input face degrades transmission and can lead to a permanently damaged fiber.
Prior to SLA installation insert the Haag-Streit focus post and turn the slit lamp illumination on. Adjust
the viewing oculars so that the focus post is crisp and clear. You will not adjust the oculars again during
this procedure. Remove focus post.
1) The slit lamp must be properly positioned prior to installing SLAh: Move the Slit lamp as far away
from the patient headrest as possible, center it laterally and lock it in position with the thumbscrew
located at lower right of slit lamp base. Swing the illumination tower 60-90° clockwise, The tower must
be in the normal, full-upright position to install SLAh.
2) Remove IRIDEX SLAh from carry/storage case. Flip Eye Safety Filter Plate down from its latched
storage position so that it is free to pivot. If this step is not performed the eye safety filter will collide
with the tonometer post potentially cracking the glass.
3) Slide SLAh onto tonometer post. When SLAh is completely bottomed out on post, secure with
Locking Thumbscrew at left side of SLAh mounting plate. Rotate the fine focus adjustment knob
clockwise, towards the patient, to avoid interference with the prism (They will not interfere when
properly aligned for use). Slowly swing illumination tower back into operating position, verifying SLAh
clearance.
4) Secure fiber optic cable to patient chin rest in gentle arc (6" minimum bend diameter with Velcro
Strap provided. Avoid sharp bends and kinks!).
5) Connect fiber and SmartKey to OcuLight laser console.
6) Set up a target (business card, paper, etc.) approximately where the patient's head will be positioned.
Move the slit lamp to a position where the white light is in focus. If you have done steps 1-5 correctly
you should be able to close the slit to approximately a 1 mm width and swing the illumination tower back
and forth with little movement of the slit.
7) Turn the laser on, set the SLA to a 75pm spot size and press Treat in order to view the aiming beam.
In this position you should be able to use the fine focus adjustment on the right side of the SLA to bring
the aiming beam in focus.
8) Adjust lateral position of laser spot within field of view with Lateral Adjust Lever centered on SLAh
mounting plate. Range of adjustment is plus and minus 2.5 mm from centerline of focus post.
Orientation of lever can be reset in the field at any time to suit individual preference using slotted flat
head screw at top of lever and screwdriver provided with slit lamp.
9) Adjust vertical position of laser spot within field of view with either Vertical Adjust Post on sides of
laser mirror frame. Range of adjustment is preset at the factory to plus and minus 2.5 mm from viewing
axis. This can be reset in the field to suit individual preferences by adjusting one or both setscrews
installed in one side of the mirror support.
