Pachymeter values (3)

P. Apex: Corneal thickness at the apex

P. Min: Corneal thickness at the thinnest point

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.

IOP Chg.: Correction of the intraocular pressure dependent on the
corneal thickness in the apex
(sec. 17, page 62) .
Correction is done based on the selected correction table. The type
of correction table can be selected in the settings.
Scheimpflug (4)
The Scheimpflug image shows the cornea between the red doted lines.
Keratometer Values (5)

Rh/Rv: 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 (

6) - repeat the measurement.
Refraction Values (6)
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 (9-8) - 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.
