Nidek OPD Scan III
NIDEK, a world leader for vision examination and diagnostic instruments has created the OPD-Scan III, the third generation aberrometer / corneal topographer that is a true refractive workstation for all practitioners.
The versatility incorporated in one compact unit allows clinicians to obtain broad and precise information about the refractive status of the eye enabling comprehensive analysis and assessment, utilizing state-of-the-art data
Task based summaries
Allow the practition to better evaluate and treat a wide variety of patients from a simple glasses prescription to complex contact lenses and refractive surgery, and especially in pre- and post- operative cataract evaluations
Faster and more accurate
Continuous development from Nidek means that the OPD-Scan III is faster, more accurate and more user freindly than ever before
Description & Technical Specs
Wavefront aberrometry gives unprecedented assessment of visual acuity and quality of vision in
addition to traditional refraction and keratometry. Simulation of retinal contrast sensitivity and visual
acuity charts enable objective quantification of visual clarity.
Corneal topography provides intuitive maps and numerical data for the corneal surface and provides neural network assisted detection of corneal pathology such as keratoconus suspect, keratoconus and pellucid marginal degeneration.
The auto refractometer provides exceptionally accurate refractions for various pupil diameters
including refractions under photopic and mesopic conditions, critical for proper assessment of both
refractive surgery patients and common refractive problems.
The auto keratometer provides conventional keratometry and novel corneal surface descriptors
such as APP (Average Pupil Power) and ECCP (Effective Central Corneal Power) which aid in the
calculation of the correct IOL power for postoperative corneas.
Pupillometer and Pupillographer
Pupillometry measures photopic and mesopic pupil diameters. Pupil images reveal the shape of
photopic and mesopic pupils, which can alter refraction and important surgical data. Identification of the first Purkinje Image (corneal light reflex) and pupil center are provided. The distance between these two landmarks is calculated to assist in centration during refractive surgery and to assess IOL centration.
