Dear Customer, thank you for choosing a KaWe pro-
duct. Our products are known for their high quality

the product!

of this product before attempting to use it.
Use:
These ophthalmoscopes are only to be used by
authorized professional personnel. They are only to
be used for the purpose of examining the fundus of
the eye.
Purpose:
KaWe ophthalmoscopes are used to exa-
mine the fundus of the eye using direct ophthalmos-
copy. The detection of characteristic changes in the
fundus of the eye enables the diagnosis of numerous
diseases. The conceptual design of the KaWe ophthal-
moscope allows for its use without pupil dilating
medication. In this case, however, the patient’s field of
sight is limited.

dance with the intended use of the unit. The manufac-

Operation of the Ophthalmoscope
1. Rekoss Lens:
If both the observer and the patient
are completely emmetropic (have perfect vision),
it should be possible to obtain a clear fundus image
without the use of a corrective lens. However, in most
cases, both the observer’s and the patient’s eyes have
refractive errors and in order to obtain a clear fundus
image, it is necessary to correct the combination of
these refractive errors. Hyperopic vision is corrected
with a “plus” lens while myopic vision is corrected with
a “minus” lens.
