1-6
[VD] Vertex distance [mm], which represents the distance between the
corneal vertex and the posterior of the corrective lens to be pre-
scribed. (When VD=CL is displayed, calculation is made for a
corneal vertex distance of "0").
[AUTO SHOT] Function by which measurement is automatically started when fo-
cusing in the directions of up/down/left/right becomes optimum.
[AUTO ALIGNMENT] Function by which alignment in the up/down/left/right directions
and the focusing direction is automatically made.
[AUTO POWER OFF FUNCTION]
The LCD screen is automatically ceased if operation is sus-
pended for a specified period of time, with the power lamp as
being left flickering. (Auto Power-Off Mode) Pressing of
whichever button returns the screen to the initial operation
screen.
[HIGH-SPEED MODE] Doing Automatic fogging at the time starting refractive measure-
ment and continue measurement by maintaining the fogging condi-
tion, which is useful for measurement of a Patient who has un-
stable eye fixation.
[AUTO FOGGING] Target is automatically moved to the far sighted side to provide
fogging, which eliminates Patient's eye adjustment.
[TOUCH ALIGNMENT] Touching of the target bright spot in the screen moves the measur-
ing head to position the target bright spot to the center of the
screen. Alignment can be made without operating the Joystick.
[TOUCH PANEL] Directly touching of the Monitor enables various operations as
well as touch alignment.
[RESIDUAL ASTIGMATISM] This implies a residual astigmatism which is calculated by
assumedly having the Patient wear a virtual hard contact lens,
which may differ the value from that for simple astigmatism
or corneal astigmatism.
[SPHERICAL EQUIVALENCE] Calculated with refractometry values, SPH + CYL/2
