Purpose/indications
The slit/spot retinoscopes described in these instructions for use (aka skiascopes) were
manufactured to determine the refraction (ametropia) of the eye.
Startup and function
Attach the required instrument head to the mount on the upper part of the handle so that the
two recesses on the lower part of the instrument head align with the two protruding guide
pins of the battery handle. Gently press the instrument head onto the battery handle and
turn the handle clockwise until it stops. The head is removed by turning it anti-clockwise.
You can now use the knurled screw to rotate the slit image and focus the slit or spot image.
Rotation
The slit image can be rotated 360° using the control element. The respective angle can be
read directly from the scale on the retinoscope.
Fixation card
For dynamic retinoscopy, the fixation cards are hung and fixed in the holder on the object
side of the retinoscope.
