Description
Nidek OPD Scan lll
“Comprehensive Vision Analysis and Assessment”
The Nidek 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. 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.
Features:
Wavefront Aberrometer – 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.
Topographer – Corneal topography provides intuitive maps and numerical data for the corneal surface and provides Classification/Indices of corneal pathology such as keratoconus suspect, keratoconus and pellucid marginal degeneration.
Auto Refractometer – 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.
Auto Keratometer – The auto keratometer provides conventional keratometry and novel corneal surface descriptors such as APP (Averaged Pupil Power) and ECCP (Effective Corneal Central 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.
Enhanced Measurement Accuracy and Ease of Use
Wider Measurement Area – The OPD-Scan III’s 9.5 mm diameter wavefront aberrometry ensures full coverage of almost any pupil. Incorporating 2,520 data points which is a 175% increase compared to the OPD Scan II, allows for enhanced measurement accuracy and spatial resolution.
Tiltable Color LCD Touch Screen – The 10.4-inch color LCD touch screen tilts, allowing viewing from different angles for easier measurements.
High Speed Printer with Easy Loading and Auto Cutter – The OPD-Scan III incorporates a high speed user-friendly printer. Printer paper can be easily changed. Printed data sheets are automatically cut for convenience.
Greater Topography Resolution, Blue Placido Rings – 33 blue placido mires provide a minimum of 11,880 data points which is 170% greater than the OPD-Scan II. The blue wavelength allows greater precision in ring detection. The reduced illumination creates a comfortable patient experience.
Fast, 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.
