Instruction Manual Myopia Master® (G/68100/EN Rev04 0820)

Refraction Values (2)

The sphere, cylinder, axis position an 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 (9-8) - the measuring results are good.
If the field has a yellow background (7-6) - the measuring results are 
critical; repeat the measurement, if necessary.
If the field has a red background (

6) - 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 (9-8) - the measuring results are 
good.
If the field has a yellow background (7-6) - the measuring results are 
critical; repeat the measurement, if necessary.
If the field has a red background (
