Nidek OPD-Scan III
The OPD-Scan III 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.
Measurements:
- Corneal SA for Aspheric IOL Selection
- Lenticular – Residual Astigmatism
- Angle Kappa/Angle Alpha
- Corneal coma for multifocal IOL qualification
- Pre/Post Toric IOL Measurements
- Pathologies (Keratoconus, Pellucid)
- Mesopic/Photopic Pupil Size
- Retro Illumination Image
- Zernike Graphs: Total, Cornea, Internal
- Corneal Refractive Power Map
Nidek OPD-Scan III Applications
- APP – Average Pupil Power for post myopic LASIK calculations
- Angle Kappa, Angle Alpha

Accurate Diagnostics
Over 20 diagnostic measurements are acquired in 10 seconds with the OPD-Scan III. Easy alignment and automatic capture of data ensures accurate readings. Wavefront data is gathered with 2,520 light vector data points from available zones up to a 9.5mm area, adding the capability to provide for calculation of mesopic refractions. Corneal topography is gathered across 11mm with 11,880 data point mapping. Blue light, 33 ring, placido disc topography is gathered in one second.
