OPD-Scan II
Refractive Power / Corneal Analyzer
ARK-10000
 Accurate and Reliable Data for Optic Diagnostics
The NIDEK OPD-Scan II provides information on corneal topography, wavefront, autorefraction, keratometry and pupillometry in one unit, utilizing state-of-the-art imaging and analysis technology developed specifically to measure normal to highly aberrated eyes.
The system offers a variety of data maps to provide information on the total refractive error, wavefront, corneal shape, internal aberrations and visual quality of the eye, allowing highly accurate and reliable information for optic diagnostics.

 Corneal Navigator* (optional)
The Corneal navigator can be integrated into the OPD-Scan II.
Utilizing various corneal parameters from topography, the Corneal Navigator automatically determines corneal features and shows by percentage the possibility of having a condition of normal (NRM), astigmatic (AST), keratoconus suspects (KCS), keratoconus (KC), pellucid marginal degeneration (PMD), myopic refractive surgery (MRS), hyperopic refractive surgery (HRS), and penetrating keratoplasty (PKP).
Instant analysis by the Corneal Navigator helps improve the quality of examination / diagnosis.
*The Corneal Navigator is developed in collaboration with Stephen D. Klyce, PhD and Michael K. Smolek, PhD.

 "The OPD-Scan II is the only instrument that couples Wavefront, Topography and Refraction into one unit. This allows the isolation of any optical problem to cornea or crystalline lens making it easier to decide if lensectomy or corneal surgery is the procedure of choice. It also provides the best data for Customized Corneal Refractive Surgery."

 "I see for the future the coupling of wavefront sensors with corneal topography devices for the optimal correction of aberrations in a patient's eye."
