OPD-Station Comprehensive Vision Analysis Software

The NIDEK OPD-Station software makes a variety of corneal, total eye and internal eye analysis possible using advanced, unique and intelligent functions including the Holladay Summary and Corneal Navigator (optional). The OPD-Station provides various maps such as the OPD HO Map, PSF, MTF, MTF Graph and Visual Acuity Chart in addition to OPD-Scan II maps. For wavefront maps such as the PSF and MTF, clinicians can slelect the target (OPD, Cornea, Internal) and also the type (Total, HO, Group) according to their needs.

Features

* Holladay Summary
The "Holladay Summary" shows the patient where the aberrations are located and how they affect the quality of vision using the Wavefront, MTF, PSF and VA-chart simulations.

"Holaday Summary" is developed in cooperation with Jack T. Holladay, MD.
o PSF Simulation
Calculates the Point Spread Function (PSF) based on the OPD-Scan measured data and corneal topography data, and displays in simulation the distribution of the point spread. The Strehl Ratio serving as a metric of the visual quality of the eye is also displayed.

o Retinal Image Simulation
Calculates the distortion of incoming light based on the result of PSF analysis, and displays the simulated retinal image of the projected chart. This simulation can be used in explanations to patients for informed consent.

o OPD HO Map
Displays in diopters the high order aberrations and shows the refractive errors which cannot be corrected with glasses.

o Averaging Multiple Exams
The OPD-Station creates an exam data average from multiple exams. Noise components such as tear film and fixation disparity are excluded, providing more stable and reliable data.

* Corneal NavigatorCorneal Navigator*
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.
