Please refer to the Instructions for Use for full cleaning guidelines.

Patient touchable parts, like the forehead rest, must be disinfected prior to every examination with a new patient to prevent transmission of infections.

For other parts of the device, regular dusting is sufficient. More stubborn dirt can be removed using a cleaning towel dampened with drinking water or alcohol at a maximum of 70%. The cleaning intervals for cleaning the complete device must be reasonable (e.g. once per week).

For the control panel, fingerprints and dust on the touch display can be removed using a display towel or a cloth made damp with drinking water.


The cost of the Refractor 900 will vary depending on the configuration you require. The Refractor 900 can be configured to include the control panel, prisms, near reading kit, acuity chart, and other accessories. For advice on which configuration may be most suitable for you and a full quotation, please contact our customer services team on 01279 883720 or email info.unitedkingdom@haag-streit.com.
