1.4 Outline of operation

This instrument is designed to calculate the
intraocular pressure. For more details regarding
accuracy, precision, and clinical comparison of the
IOP measurements to the Goldmann applanation
tonometer please refer to Section 4.3 of the
Instruction Manual.
FT-1000 is an instrument used to measure the intraocular pressure of a patient's eye.
The patient this instrument is indicated for the measurement of intraocular pressure
without contacting the eye to aid in the screening and diagnosis of glaucoma places
their chin on the chin rest and looks into the sight-fixing lamp in the measurement
window to fix their sight.
After the physician observes the patient's eye on the monitor screen and roughly aligns
the measuring position, fine alignment and measurement is automatically conducted.
When the intraocular pressure cannot be measured automatically, align the measuring
position with the joystick and press the measurement button to start measurement.
When measurement has started, air blows from the nozzle of the measurement
window. When the cornea becomes flat due to blown air, corneal reflex light from the
light source is received by the light receiving element. The instrument calculates the
intraocular pressure according to the air pressure at this moment and shows the result
on the monitor screen.
Touch the "PRINT" button to print out the measurement data.
