Software for device provides corneal, total eye analyses

November 1, 2005

Nidek has released new diagnostic software called the OPD-Station that lets clinicians use data from its OPD-Scan device to perform a variety of corneal, total eye, and internal eye analyses using several sophisticated new functions.

Nidek has released new diagnostic software called the OPD-Station that lets clinicians use data from its OPD-Scan device to perform a variety of corneal, total eye, and internal eye analyses using several sophisticated new functions.

"The software program has more reports and functionality than the actual software on the OPD-Scan because it is intended for review and for other reports and analyses that one may want to generate from original exams," Dr. Holladay said.

New software functions

New functions available on the OPD-Station include maps of point spread function (PSF), modulation transfer function (MTF), and retinal image simulations. It also has improved color mapping. The PSF, MTF, and retinal image simulations are collectively known as the Holladay Summary.

The PSF simulation is based on aberrometry and corneal topography data measured by the OPD-Scan and displays a simulation of the distribution of the point spread, Dr. Dougherty said. Results of these PSF simulations can then be used to generate retinal image simulations of a projected eye chart.

"Clinicians can demonstrate to patients what they are likely to see with various forms of refractive surgery or better explain their refractive surgery outcomes," Dr. Dougherty explained.

"This is useful to help determine whether someone's visual complaints are primarily corneal or related to the lens," he added. "Particularly in this era of increased use of wavefront laser surgeries as well as wavefront and phakic IOLs, this software often will help the surgeon determine the proper course of action in evaluating patients with respect to which surgery is most appropriate for them, whether it be a corneal or a lens-based surgery."
