This chapter explains the flow of operations and the basic measurement procedure.
Flow of Operations
The TX-20 has three alignment modes (full auto, auto, and manual).
Full auto: Alignment, measuring left and right eyes, and printing the results of the measurement are
all done automatically.
Auto: Alignment and 1 measurement are done automatically. This mode is used to do
measurements one eye at a time while checking the condition of the eye, such as for
patients who cannot keep their eyes open continuously.
Manual: All operations are done manually. This mode is used when full auto or auto modes cannot
be used, such as when the patient’s pupil is eccentric or cornea is deformed.
The flow of operations is shown in the flow chart bellow. The items with gray backgrounds are performed
automatically.
