Nidek OPD Scan III

Nidek OPD Scan III Corneal Analyzer is an autorefractor,
keratometer, pupillometer (up to 9.5mm),
corneal topographer, and integrated wavefront aberrometer.
The OPD-Scan III completes 20 diagnostic metrics in
less than 10 seconds per eye (including angle kappa,
HOAs, average pupil power, RMS value,
and point spread function).

Easy alignment and automatic capture of
wavefront aberrometry data ensures accurate readings.
Wavefront aberrometry data is gathered from
available zones up to a 9.5mm area,
adding the capability to provide for calculation of
mesopic refractions. Blue light,
33 ring, placido disc topography is gathered in one second.
Mapping methods include OPD,
visual acuity corneal topography/topographer, and more.

Next Generation of Refractive Eye Care
The unique Nidek OPD-Scan III Corneal Analyzer is
an advanced vision assessment system that
combines topography, wavefront, automated refractor,
keratometry, and pupillometry.

Make Optimal Decisions Easily
The OPD-Scan offers multiple map summaries to
suit you practice or clinical requirements with
easy-to-understand patient reports and
even more details for comprehensive vision analysis.

Enhanced Patient Comfort
33 blue placido mires provide a minimum of
11,880 data points which is more than 170% of the OPD-Scan II.
The blue wavelength allows greater precision in ring detection.
The reduced illumination creates a
comfortable patient experience.

Outcome Simulation of Postoperative Corneal Shape and
Total Eye Refraction
The optional Final Fit software evaluates and
converts the OPD-Scan III refractive and topographic data to
produce the precise customized ablation parameters for
the NIDEK EC Quest Excimer Laser System.

Accurate Diagnostics
Over 20 diagnostic measurements are acquired in 10 seconds.
Easy alignment and automatic capture of
data ensures accurate readings.
Wavefront data is gathered from available zones up to
a 9.5mm area, adding the capability to provide for
calculation of mesopic refractions. Blue light, 33 ring,
placido disc topography is gathered in one second.

Data View Options
Axial, gradient, instantaneous, numeric K display,
numeric power display, PSF (point spread function),
zernike graph (including corneal), contact lens summary,
VA-ETDRS simulations, internal OPD, eye image,
comparison maps, and difference maps.

Unique Features
Cataract and refractive surgeries have now been taken to
another dimension. Detailed patient summaries are available in
just a matter of seconds. Pre-op toric axis alignment can
be mapped to iris or other physical landmark positons.
Retro illumination images can be used post-op to
verify IOL axis alignment.

Dysfunctional Lens Syndrome (DLS)
The above map is a measurement of a prior myopic LASIK
patient with Dysfunctional Lens Syndrome (DLS).
The Point Spread Function (PSF) maps show that
the cornea is contributing to the problem but the majority of
the patient’s issue is lenticular change.
The patient thought she needed another LASIK treatment,
when in actuality, the lens changed.

Day/Night Wavefront Refractions
Pupillometry measurements are utilized to allow for
the calculation of separate wavefront refractions at
4mm and 6mm pupil sizes (or mesopic if smaller than 6mm).
This provides information on the stability of the refractive error
as pupil size changes, and the individual starting points for
separate day and night refractions, if indicated.

Your patients can receive a state of the art printout of
their ‘before’ and ‘after correction’ chart or understand why
they are not able to achieve 20/20. Welcome to
the next generation of refractive eye care.
