Term Description Page
Simulation How the target can be seen when complete correction is
performed can be simulated. Without any high-order
aberrations, the target can be seen clearly. However, with
high-order aberration, the target can not be seen clearly
even after complete correction.

Smoothing The Topo-map smoothing function performs analyses by
changing the production algorithm of map information of
the Axial Power map and Instantaneous Power map.
99
Sph Spherical refractive power. 104
Spherical Aberration Aberrations of even orders (as 4th, 6th, etc.) of Zernike
polynominal equation are expressed altogether as spher
-
ical aberration.
105
Summary map (analysis
result display map)
When right and left eyes are measured more than once,
Summary map can display ocular total aberration and
Landolt's ring simulation for each measurement.
86
Tap Light touch to button on screen. 13
Temporary Setting Function used to temporarily perform measurements
under certain conditions. Single-eye measurement mode,
IOL mode, etc. can be set. After measurement (and data
output), the system returns to the initial status.
114,124
Tetrafoil A type of high order aberration.
Shows aberration of the 4th order of Zernike polynominal
equation (-4 and 4 terms).
85,143
Third-order display In KR-1W, 3rd order terms of Zernike polynominal equa-
tion are displayed.
84
TopoMap overlay Overlay of the Corneal Axial map and Corneal Instanta-
neous map can be overlayed to the corneal Mire image
of the Corneal Aberration map.
100
Total HOA (Total High
Order Aberration)
Analyzed total high order aberration. 88
Trefoil A type of high order aberration.
Shows 3rd order terms of Zernike polynominal equation
(-3 and 3 terms)
107,143
Vertex distance Means the right-left vertex distance. 16,131
Waiting Position After
Measurement
KR-1W can select the waiting position of measuring head
after finishing auto mode measurement.

Wave-front/PSF Image PSF is short for Point Spread Function. In the KR-1W, it
is possible to see how the point light source is focused,
after being completely corrected and affected by aberra
