Laser treatment using VISULAS YAG III/
VISULAS YAG III Combi/VISULAS Trion Combi
Note for VISULAS Trion Combi:
When operting the VISULAS Trion Combi with the ACCENTO
eyepiece, both devices (VISULAS Trion and VISULAS YAG III) should
be switched on.
Adjusting the slit lamp and eyepieces
Before treating a patient with laser radiation you should be perfectly familiar
with the use of the slit lamp. Read the user manual carefully, paying
particular attention to the safety notes.
•
Make sure the eyepieces are completely plugged in and the eyecups
pulled out (for spectacle wearers: pushed in).
•
Turn the diopter setting ring on both eyepieces fully in a + direction (anti-
clockwise) as far as they will go.
•
First of all, attach a piece of paper (business card or similar) to the object
plane of the slit lamp.
•
Center the slit projector and binocular tube to the slit lamp base.
•
On the slit lamp, choose the highest magnification.
•
Open the slit.
•
Look through the eyepieces. Use the joystick to focus on the paper
surface and lock the slit lamp base.
•
Close the illuminating slit to a narrow line.
•
On the slit lamp, choose the lowest magnification.
•
Look through each eyepiece in turn, rotating the diopter setting ring for
the eyepiece through which you are looking in the
−
direction (clockwise)
until the surface of the paper is sharply in focus.
•
Select the other magnification steps on the slit lamp.
•
The image should remain sharply in focus at all magnifications. If not, the
procedure should be repeated.
•
Make a note of the eyepiece settings for future treatment sessions. In
future you will need only to adjust the eyepieces to these values.
If more than one physician uses the device, it is recommended that
a table be prepared with the individual refractive powers and kept
in a handy location near the device.
