INDICATIONS FOR USE

These devices are intended to be used only by suitably trained and authorised healthcare professionals.

CAUTION: Federal Law restricts this device to sale by or on the order of a physician or practitioner.

Intended use / purpose of instrument

Keeler Jazz Ultra Otoscopes are indicated for the examination of the health of the external auditory canal, the tympanic membrane, and the middle ear. Otoscopy can aid in the detection of ear conditions, including but not limited to earache, ear infection, hearing loss, ringing in the ears, inflammation, and foreign bodies.

Keeler Jazz Ultra Ophthalmoscopes are indicated for examining the posterior segment of the eye referred to as the fundus, to aid in the screening and diagnosis of retinal pathology including, but not limited to, diseases such as cataracts, papilloedema, glaucomatous disc cupping, diabetic retinopathy, hypertensive retinopathy and retinal detachments. When set to a high power and magnification, it can also be used to examine the anterior segment of the eye, which includes the eyelids, cornea, sclera, conjunctiva, iris, aqueous, crystalline lens and anterior vitreous.

SAFETY

PHOTOTOXICITY

CAUTION: The light emitted from this instrument is potentially hazardous.

The longer the duration of exposure, the greater the risk of ocular damage. Exposure to light from this instrument when operated at maximum intensity will exceed the safety guideline after 21 minutes.

While no acute optical radiation hazards have been identified for Diagnostic Instruments, we recommend keeping the intensity of the light reaching the patient’s retina to the minimum possible for the respective diagnosis. Children, people with aphakia and people suffering from eye conditions are most at risk. An increased risk may also occur if the retina is exposed to the same or a similar device with a visible light source within 24 hours. This applies, in particular, if the retina has been photographed with a flashbulb in advance.

Keeler Ltd shall on request, provide the user with a graph showing the relative spectral output of the instrument.
