Uses same core software as OPD-Scan; adds visualization tools including Point Spread Function (PSF), Modulation Transfer Function (MTF), MTF graphing, Visual Acuity mapping, and improved color mapping. Operated by physicians in clinical settings to review diagnostic data; facilitates clinical decision-making regarding corneal shape and refractive status; benefits patients through enhanced data visualization and management. ## Clinical Evidence No clinical data provided. Substantial equivalence supported by performance data demonstrating the software meets specified requirements. ## Technological Characteristics Stand-alone software application for independent PC; interfaces with Nidek NAVIS data management package to access OPD-Scan measurement data. Implements visualization algorithms for PSF, MTF, and refractive mapping. Software-based analysis of corneal shape and refractive power. ## Regulatory Identification An ophthalmic refractometer is an automatic AC-powered device that consists of a fixation system, a measurement and recording system, and an alignment system intended to measure the refractive power of the eye by measuring light reflexes from the retina. ## Predicate Devices - Topographic Modeling System ([K944207](/device/K944207.md)) - Nidek OPD-Scan ([K003299](/device/K003299.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Ltd. | K003299 | March 9, 2001 | {1}------------------------------------------------ #### DEVICE DESCRIPTION Nidek has developed a stand-alone software option for users of the OPD-Scan™ device called OPD-Station, which will run on an independent PC (i.e., separate from the OPD-Scan™ device). The OPD-Station software is able to access data measured by the OPD-Scan™ device via a separate Nidek data management software package called NAVIS. The OPD-Station uses the same software as that used for the OPD-Scan device so that a physician can view OPD-Scan data on their PC of choice. However, the OPD-Station software has the following new functions: - Maps of Point Spread Function (PSF), Modulation Transfer Function (MTF), MTF . graphing, and Visual Acuity mapping - Improved color mapping . #### INTENDED USE The OPD-Station software is indicated for use in analyzing the corneal shape and refractive powers measured by the OPD-Scan Models ARK-9000 or ARK-10000, and to display the data in the form of maps, and manage the data. ### TECHNOLOGICAL CHARACTERISTICS A comparison of the technological characteristics of the OPD-Station software and the predicate devices has been performed, and the results of this comparison demonstrate that the OPD-Station software is equivalent to the marketed predicate devices #### PERFORMANCE DATA The performance data indicate that the OPD-Station software meets all specified requirements, and is substantially equivalent to the predicate devices. {2}------------------------------------------------ Image /page/2/Picture/1 description: The image is a black and white logo for the U.S. Department of Health & Human Services.
