Use Instructions

1. Make sure the laser emission is off.
2. Turn the slit lamp on and adjust a
proper illumination brightness.
3. Place the object plane post provided with
the slit lamp to its intended position. If the
post is not available, follow these steps:
a. Fix a piece of paper or carton to the
headrest to a position where the slit
lamp beam is projected onto it.
b. Set the slit lamp eyepieces to 0.
c. Set the slit lamp magnification
to the highest setting.
d. Move and lock the slit lamp to a
position where the slit lamp beam is
in focus (beam edges are sharp).
4. Set the slit lamp beam to a 3 mm round spot.
5. Turn the ML6710i aiming beam on in pulsed
mode. Adjust brightness if needed.
6. Adjust the SLA native spot (in air, no lens) to 3
mm diameter. Note that the selected contact
lens is included in the spot reading given on
the screen. For instance, a spot reading of 6
mm with SuperQuad 160 lens equals 3 mm
SLA native spot (Figure 33 for reference).
7. Make sure the SLA spot location
matches that of the slit lamp spot. If
needed, adjust the horizontal and vertical
position of the SLA spot as shown in
Figure 51 and Figure 52, respectively.
8. Make sure SLA focal plane (SLA spot has
sharp edges on the target plane) matches
that of the slit lamp spot. If needed, adjust the
focal of the SLA spot as shown in Figure 53.
MANDATORY
In case of misaligned SLA output spot, follow the re-focus protocol
below to avoid incorrect spot characteristics and wrong dose.
Figure 53. Adjustment of the spot location
vertically by tilting the mirror with a
dial (highlighted with the circle).
