Refraction Results
After performing the measurement the following display appears.
Refraction Values (2)
The sphere, cylinder, axis position and quality values are displayed in this
field.
The refraction values are measured three times. The mean value is
displayed in the fourth line.
Q-value:
If the field has a white background (9-7) - the measuring results are good.
If the field has a yellow background (6) - the measuring results are
critical; repeat the measurement, if necessary.
If the field has a red background (
≤
5) - repeat the measurement.
Keratometer Values (3)
K1/K2: Horizontal/vertical radius of curvature in the center
blue: flat meridian
red: steep meridian
Pupil: Size of pupil
Astig: Astigmatism of cornea in the center
WTW: (white-to-white) Cornea diameter or iris diameter.
Q-value:
If the field has a white background (9-7) - the measuring results are
good.
