Topographic autorefractometer OPD-SCAN III

Nidek OPD-Scan III Topographic Autorefractometer - the complete aberrometer 

This device combines several essential ophthalmic functions. Equipped with an intuitive touch screen, it is easy for vision professionals to use on a daily basis.

This versatile machine simplifies measurements by combining corneal aberration, auto-refractometry, auto-keratometry, corneal topography and pupillometry into a single unit. Its special feature is the OPD Map (Optical Path Difference), generating a detailed diopter map of the explored pupillary zone, up to 9.5 mm.

The OPD-Scan III stands out for its differentiated aberrometry, distinguishing between corneal and internal aberrations. Its acquisition is based on dynamic skiascopy, offering numerous qualitative measures (total and high-degree aberration map, OPD map, topographic elevation map, PSF image, MTF graph, Visual Acuity map by convolution, "Day" and "Night" scenic tests, toric implant implantation aid, etc. ) and quantitative (objective refraction, RMS values, HOA RMS values, rate of each aberration, Zonal Refraction map showing the distribution of ametropias in OPD measurement, keratometry, mesopic and photopic pupillometry, keratoconus screening indices, calculation of corneal diameter, etc.).

The integration of 3D Eye-Tracking and automatic measurement triggering enhances the accuracy and efficiency of examinations. Topographic and diopter aberration maps provide detailed visualization of ocular characteristics. The "Overview" summary screen summarizes results, while specific screens facilitate analysis for applications such as contact lenses, toric intraocular lenses, laser surgery, cataracts and more.

In addition to providing detailed results, OPD-Scan III offers visual quality simulation and diagnostic support with corneal disease statistics. Its adaptability to different types of work organization makes it accessible and functional in a variety of clinical environments.
