2. SAFETY
2.1 WARNINGS AND CAUTIONS
Please note that the proper and safe functioning of our instruments is only guaranteed if both
the instruments and their accessories are exclusively from Keeler Ltd.
Observe the following precautions in order to ensure safe operation of the instruments.
WARNINGS
• Never use the instrument if visibly damaged and periodically inspect it for signs of damage
or misuse.
• Check your Keeler product for signs of transport / storage damage prior to use.
• US Federal Law restricts this device to sale by or on the order of a physician or practitioner.
• The owner of the instrument is responsible for training personnel in its correct use.
• 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.
• The contact surface of the prism should be checked before each use for damage and
discarded if damage is found.
• 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.
• Keeler Applanation Tonometers should be serviced and calibrated annually. Any servicing
or repairs / modifications should only be carried out by Keeler Ltd. or by suitably trained
and authorised distributors. The manufacturer declines any and all responsibility for loss
and / or damages resulting from unauthorised repairs; furthermore, any such actions will
invalidate the warranty.

Relationship between the pressure of
the measurement drum and the force
and pressure on the applanated surface.
The intra-ocular pressure, expressed in
mmHg, is calculated by multiplying the
drum measurement by ten (for conver-
sion from one unit to another).
