What is the NIDEK OPD-Scan III?

The OPD-Scan III is a multifunctional ophthalmic analyzer that evaluates both lower-order and higher-order aberrations while simultaneously measuring corneal shape and refractive status.

Unlike conventional autorefractors, the OPD-Scan III provides detailed optical quality analysis, helping clinicians determine the underlying causes of poor visual performance.

Integrated Diagnostic Technologies

Wavefront Aberrometry

Wavefront technology measures the way light travels through the entire optical system of the eye.

The OPD-Scan III evaluates:

• Total ocular aberrations
• Higher-order aberrations (HOAs)
• Lower-order aberrations (LOAs)
• Internal aberrations
• Corneal aberrations
• Ocular optical quality

Corneal Topography

The integrated Placido-disc topographer generates detailed maps of the anterior corneal surface.

Available maps include:

• Axial curvature map
• Tangential curvature map
• Elevation map
• Refractive power map
• Corneal irregularity analysis
• Corneal astigmatism analysis

These measurements are essential for:

• Keratoconus screening
• Contact lens fitting
• Corneal disease evaluation
• LASIK planning
• Corneal transplant follow-up

Objective Autorefraction

The system automatically measures:

• Sphere (SPH)
• Cylinder (CYL)
• Axis (AX)

Automated Keratometry

Precise keratometry measurements include:

• Flat K
• Steep K
• Average K
• Corneal radius
• Corneal power
• Astigmatism axis

Pupillometry

Dynamic pupil analysis measures pupil diameter under various lighting conditions.

Applications include:

• Refractive surgery evaluation
• Premium IOL selection
• Night vision assessment
• Optical quality analysis

Retroillumination Imaging

The retroillumination function visualizes abnormalities within the crystalline lens and cornea.

Clinical applications include:

• Cataract evaluation
• Lens opacity documentation
• Corneal scar assessment
• Corneal dystrophy evaluation

Advanced Vision Analysis

Optical Path Difference (OPD) Analysis

The OPD technology measures the difference between the ideal optical path and the actual optical path through the eye.

This analysis provides valuable insight into:

• Visual quality
• Contrast sensitivity
• Optical performance
• Aberration distribution
• Functional vision

Higher-Order Aberration Analysis

The OPD-Scan III identifies subtle aberrations such as:

• Coma
• Trefoil
• Spherical aberration
• Secondary astigmatism
• Tetrafoil

Cataract Functional Analysis

Beyond detecting lens opacity, the system evaluates how cataracts affect overall optical quality.

This helps clinicians determine the optimal timing for cataract surgery.

Clinical Applications

The OPD-Scan III provides an all-in-one diagnostic platform for routine ophthalmic evaluations.

Suitable for:

• General ophthalmology
• Optometry practices
• Vision screening centers
• Eye hospitals

Refractive Surgery Planning

The system supports preoperative assessment for:

• LASIK
• PRK
• SMILE
• Phakic IOL implantation
