Nidek reliability and precision

TECHNICAL DESCRIPTION
Pupil imaging
The HandyRef-K analyzes a pupillary area up to 4mm in
diameter. With this extended measurement range,
more data close to subjective refraction
subjective refraction. Smaller pupils from 2mm in
diameter are also measured.
Keratometry
A Placido sight is projected onto the corneal surface,
to minimize the influence of the upper eyelid.
Ø 1-4mm
Fast measurement mode
Faster, easier measurements are taken with this mode,
which is suitable for patients who have difficulty fixing.
Music can be switched on to attract attention
and calm children.
Auto shot
Automatic triggering
When alignment and focus are optimal,
measurements are taken automatically.
An alignment indicator is displayed to facilitate measurement.
Too far Too close Optimum condition
SLD/CCD technology
Coupling the SLD (Super Luminescent Diode) with
the high-sensitivity CCD sensor ensures sharp images even
when retinal glare is low.
A cataract mode is automatically activated when
measurements are not obtained in standard mode.
SynchroScan technology
Measurements start as soon as the eye is aligned,
and only data obtained through optimal alignment are
retained. This new method delivers stable,
more efficient values.
