Nidek OPD-Scan III Corneal

The topographer generates intuitive maps of
the corneal surface and indices of corneal pathology such as
keratoconus or pellucid marginal degeneration.
With 33 blue Placido mires providing a minimum of
11,880 data points, the resolution is increased in
comparison with the. The blue mires allow greater precision in
ring detection, and the reduced level of illumination presents a
more comfortable experience to the patient.

I, an advanced vision assessment system that
combines topography, wavefront, automated refractor,
keratometry, and pupillometry.

The autorefractometer provides accurate refractions under
mesopic and photopic conditions—data that may be
important for planning refractive surgery or
analyzing common refractive problems.
The autokeratometer, in addition to
standard keratometric measures such as simulated K,
also provides novel corneal surface descriptors,
such as average pupil power and
effective central corneal power, which can aid in
calculating IOL power for eyes after refractive surgery.
Finally, the pupillometer/pupillographer measures
photopic and mesopic pupil size and documents the shape of
the pupil under these conditions,
which may alter refraction and affect surgical planning,

Nidek OPD-Scan III Corneal is a device that
mainly measures corneal shape (topographer) and
refractive error (refractometer).
It clarifies causes of vision difficulties through wavefront
analysis of information measured over a wide area.
