Academic and Clinical
Excellence with the iTrace

If you’re a practitioner interested in learning more about the ways the iTrace can benefit your practice, just give us a call — a representative from Tracey Technologies will be more than happy to answer any questions you may have as you make your decision about our technology!

We also understand, though, that a big part of the decision about whether to adopt a new technology involves doing your research and making sure the device can provide the results that you need in an accurate, repeatable manner.

We believe that the iTrace is unrivaled in terms of the information it can provide to doctors — and you can have faith that all of that information is generated in the most precise way possible. After all, as one of the most trusted devices by academic researchers, the iTrace has been used in clinical studies since the technology was developed.

Studies that Focus on the iTrace or Its Technology

There’s a growing base of research that exists in which the primary methods of the iTrace are studied and/or compared against similar functions of competing devices. We’ve listed the most notable examples here for your benefit:

“Comparison of laser ray-tracing and skiascopic ocular wavefront-sensing devices”, Eye, 2009

Go to Link
This study makes a direct comparison between the proprietary Ray Tracing technology used by the iTrace and the dynamic skiascopy used by its main competitor. The conclusion suggests that Ray Tracing lends the device the precision needed to detect higher order aberrations (HOAs) better than competing technology.
“Correlations of Objective Metrics for Quantifying Dysfunctional Lens Syndrome With Visual Acuity and Phacodynamics”, Journal of Refractive Surgery, 2017

Go to Link
Researchers in this study compared the iTrace’s proprietary Dysfunctional Lens Index scale with conventional means of testing lens opacity and dysfunction. The study finds a correlation between the DLI and traditional comparison factors, implying that the iTrace meets the standards of accuracy needed for the optimal diagnosis of a dysfunctional lens.
“Clinical evaluation of toric intraocular lens implantation based on iTrace wavefront keratometric astigmatism”, BMC Ophthalmology, 2020

Go to Link
This study tested the iTrace’s proprietary calculations of corneal astigmatism as a way to understand the accuracy and fit of the device to be used in planning effective toric lens procedures. Researchers found the iTrace’s built-in toric calculator to be “safe and effective” for application in this setting.
“Dysfunctional Lens Index Serves as a Novel Decision-Maker for Age-Related Nuclear Cataracts”, Current Eye Research, 2019

Go to Link
Cross-sectional research was carried out to compare the Dysfunctional Lens Index (DLI) with several other methods of assessing lenticular opacity, including the objective scatter index (OSI) and Scheimpflug-based average lens density (ALD). The DLI was assessed to be more accurate than comparative techniques.
“Objective accommodation measurements in pre-presbyopic eyes using an autorefractor and an aberrometer”, Journal of Cataract & Refractive Surgery, 2008

Go to Link
In a study that compared the iTrace wavefront aberrometry’s effectiveness in measuring accommodation in pre-presbyopic eyes, the iTrace was found to be suitable for use in this application.
“Comparison of Dysfunctional Lens Index and Scheimpflug Lens Densitometry in the Evaluation of Age-Related Nuclear Cataracts”, Journal of Refractive Surgery, 2016

Go to Link
This study compared the accuracy of the iTrace’s key method of measuring and assessing the density of age-related nuclear cataracts to a few other subjective and objective methods. Researchers concluded that “the DLI may improve the preoperative evaluation of a nuclear cataract and the monitoring of its progression.”

Studies in Which the iTrace Is Used

Below you can find selections from a growing body of research in which the iTrace was used as a method of gathering data central to the study’s core focuses. In fact, the iTrace has been used by almost every company in the prebyopic treatment space to study the results of these devices and therapies.
