the instrument.
• This device is intended to be used only by suitably trained and
authorised healthcare professionals.
• US Federal Law restricts this device to sale by or on the order
of a physician or practitioner.
• Accuracy of applanation IOP measurements is known to be affected
by variations and changes in corneal rigidity due to differences in
corneal thickness, intrinsic structural factors or corneal refractive
surgery. It is recommended that these factors are considered during
IOP measurement.
• Never use the instrument if visibly damaged. Periodically
inspect it for signs of damage or misuse.
• The contact surface of the prism should be checked before each use
for damage and discarded if damage is found.
• Check your Keeler product for signs of transport / storage damage
prior to use.
• We recommend that the prism is not used when it becomes more
than two years of age as, after this time it is possible that body or
sterilising fluids may seep inside leading to possible sterility and cross
contamination issues.

Cleaning (Section 4) of this instruction manual.
• Use only cloths dampened with water to clean the Applanation
Tonometer body. Do not use corrosive products or alcohol.

loss and / or damages resulting from unauthorised repairs;
furthermore, any such actions will invalidate the warranty.
• Never use the instrument if the ambient temperature, atmospheric
pressure, and/or relative humidity are outside the limits specified in
this manual.
• Should the instrument suffer shocks (for example, should it
accidentally fall), follow the check procedure outlined in the
'Servicing and Calibrations' (Section 12); if necessary, return the
instrument to the manufacturer for repair.
