1.3 Glossary
[AS] : Auto Shot.
Function to automatically start measurement when the
patient's eyes are within the measuring range.
[MS] : Manual Shot
[AA] : Alignment Assist.
Auxiliary alignment function in vertical direction only. When
the patient’s eye is close to the measuring range, the head
position automatically moves up/down toward the alignment
target.
[D] : Diopter (Unit for expressing the dioptry; inverse of meters)
[Ks] : Direction and value of the meridian with the largest refractive
power are displayed.
(“s” of “Ks” stands for “steep.”)
“Spherical” is displayed when the difference between the
major meridian value and minor meridian value is less than
0.2D.
[Kf] : Direction and value of the meridian that intersects Ks at right
angles are displayed.
(“f” of “Kf” stands for “at.”)
[MinK] : Direction and value of the meridian with the smallest
refractive power are displayed.
[AvgK] : The average refractive power of Ks and Kf is displayed.
[CYL] : Displays the difference between Ks and Kf as the
components of a corneal cylinder in diopter units.
[Pachymetry(Apex)] : Displays the corneal thickness [µm] at the corneal vertex
position.
[Pachymetry(Thinnest)] : Displays the thinnest corneal thickness [µm] and its position
from the corneal vertex using X / Y coordinates [mm].
[Es/Em] : The eccentricity when approximating the corneal shape (Es
in the Ks meridian direction and Em in the MinK meridian
direction) as an ellipse is displayed.
