Avoid examinations in case of
eye infections or injured corneas
• There is no contraindication for performing tonometry. Medical
assessment is necessary and due care is to be exercised.
Only clean and disinfected measuring
prisms should be used
• Examinations should only be conducted with cleaned and
disinfected measuring prisms.
• Tonometer prisms are not dispatched in a disinfected state
and should always be disinfected before use.
• The disinfecting of contact glasses eg. with cotton wool or
damp cloth without putting them into disinfecting fluid is insuf-
ficient and not allowed.
• Incorrect medical disinfecting fluid can cause patients to be
infected and can also cause damage to the eyes.
• Residue of the disinfecting may cause provoking or caustic
reactions on the patient's eye, therefore rinse thoroughly.
• Measuring prisms must be removed from the holder and be
put into disinfecting fluid.
• Cleaning and disinfecting is to be carried out according to
Appendix B, Paragraph B.3 and short manual.
No damaged prisms
should be used
•
Before each use
the contact surface of all prisms should
be verified for contamination or damage (such as scratching,
rips or sharp edges). The slit lamp microscope is best used
for this purpose at a magnification of 10x to 16x.
• If cracks form, the disinfectant may get into the hollow inte-
rior and can enter the patient's eye while tonometry is taking
place, leading to irritation of the cornea. Defective measuring
prisms should not be used, in order to avoid any damage to
the cornea of the patient.
• In case of inaccurate measuring results, please observe the
functional verifications according to Appendix B.
Control
• This type of sensitive measuring equipment is to be checked
after exposure to external force (e.g. unintentional shocks or
being allowed to fall) in accordance with Appendix. If repair is
necessary please contact your Haag-Streit distributor.
