Characteristics
Screening
Measures basic information related to corneas and entire ocular
refraction.
Pupillometry
Measures pupil diameters, REF values, and high-order aberra-
tions in dark and bright places.
Dry eyes
Measures ten times successively in an interval of one second for
about ten seconds. This indicates progressive change in the
ocular characteristics.
Cataract
Provides useful information for the best Hartmann selection
before operation as well as used to check the condition after the
operation. It has a longer exposure time to make it easier to
measure the point image with the cataract eye.
Over refraction Checks the condition when glasses are worn.
Custom
Provides measurement and report output according to the set-
ting made in the Setup screen.
