KaWe E10 Medical Ophthalmoscopes

We would like to thank our valued customers for their decision to purchase a KaWe product. Our ophthalmoscopes are characterized by high quality and durability. KaWe ophthalmoscopes meet the requirements of Regulation (EC) 2017/745 (European Regulation on Medical Devices) and are classified as medical devices class I.

Please read this manual carefully, adhere to it strictly, and keep it for future reference if necessary. Before using the product, carefully study operation rules, especially care requirements.
If you have any questions concerning device operation, please contact the service department (the manufacturer’s address is indicated on the back).

KaWe ophthalmoscopes are available in two models:

• EUROLIGHT: Models with metal handle and plastic button
• PICCOLIGHT: Models with plastic handle and button

Images are shown on the cover of this application manual. The difference between the two models are described in this appli-cation manual. Other options (battery operation, light sources, etc.) are not discussed in detail, as they do not have significant differences in service.

Symbols used in the application manual and on packaging

Purpose and intended use

KaWe ophthalmoscopes are diagnostic instruments and are primarily used for optical examination of the fundus by direct ophthalmoscopy. In this method, the central elements of the visual organ, such as optic disc, the vascular bundle, macula (Makula lutea) are examined. The ophthalmoscope allows examinations without the use of mydriatics. However, in this case, the patient‘s field of vision is limited.

• Target patient groups: Patients of all ages and genders who require visual examination.
• The product must only be used by authorized specialized personnel!

Intended use is the compliance with all instructions in this application manual as well as basic rules and directives. The manufacturer does not accept any liability for damage resulting from any other use.

Safety rules/contraindications

• Before each use, please check whether the ophthalmoscope is operating properly. Do not use the device in case any damage is detected.
• Ensure the ophthalmoscope is protected from moisture.
• Avoid direct contact of the ophthalmoscope with the visual organ.
• If the light is on for a long time, the areas around the lamp may become hot.
• KaWe ophthalmoscopes are not intended for use during surgery.
• Use only KaWe MedCentether 5000 wall-mounted station for power supply of KaWe EUROLIGHT E25 head.
• Do not use the device in areas subject to strong magnetic fields (MRI systems).
• When handling ophthalmoscopes – as with all energy-consuming diagnostic devices – special electromagnetic compatibility (EMC) precautions must be observed.
• The performance of ophthalmoscopes can be affected by mobile high-frequency communication devices.
• Only original spare parts and accessories from KaWe may be used.

In case of a malfunction, a large amount of heat can be generated, resulting in an increased risk of fire. In case of strong heat, turn off the handle.

Installation and maintenance

When handling the instrument, it is necessary to take into account that the examiner must bring his eye as close as possible to the instrument. Due to the lateral illumination of the patient‘s fundus area and the approach to a maximum distance of 2-3 cm, diagnostics can be carried out without drugs.

Duration of operation
The devices are not intended for continuous operation, the maximum duration of one use is 1 minute with a 10 minutes pause between uses.

Maintenance and Service

The end of the useful life is usually determined by wear and tear. Damaged parts are to be sorted out and replaced immediately. If the light intensity decreases, check for the following possible causes:

1. Battery charge; replace or recharge if necessary.
2. Clean or replace the lamp.

If the above reasons are excluded, repair or replacement may be required. In this case, please, contact a specialized dealer.

Battery replacement
Check the batteries charge regularly. Low battery voltage (depending on consumption) leads to light intensity decrease and possible appearance of LED lamps flashing. In both cases, it’s necessary to replace the batteries. When replacing, use only new, high quality alkaline batteries (or fully charged batteries).

Besides, observe manuals requirements for use of the batteries.

Lamp replacement
The correct performance of the ophthalmoscope with original light quality is only ensured when using original KaWe replacement lamps.
