Our Commitment to Innovation

Ongoing Advancement and the iTrace Visual Analysis


The story of the iTrace is one of decades of research, testing, and a commitment to constant innovation. At the turn of the century, what would eventually become the modern iTrace was a tool used mainly by clinical professors and research scientists. Its unique view of ocular function made it a critical tool in establishing the data that brought new products from Alcon, Johnson & Johnson, and others to market.

Because the iTrace is the only tool on the market that uses proprietary ray tracing to get a truly objective simulation of functional vision, doctors ultimately realized the true potential of this unique scanning device. By the first decade of the 2000s, the iTrace became a critical tool for doctors that wanted to gain unprecedented insight into their patients’ vision.

With each new enhancement we have made to the iTrace over the last decade, Tracey Technologies reaffirms our commitment to doctors and their patients. Ensuring your patients’ quality of vision remains our top priority. Here’s how far the technology has come:


The current version of the iTrace helps doctors more accurately diagnose lens dysfunction and ensure patient satisfaction with a Toric IOL. If you are using the iTrace without the following capabilities, please contact us to upgrade your software to the latest version.

Diagnostic Precision

The Dysfunctional Lens Index is an objective calculation of the earliest appropriate time to remove a patient’s lens. This grading, which ranges from 0-10, accompanies a patient-friendly visual display.

Toric Satisfaction

The Toric Check display calculates cross cylinder and verifies whether a toric IOL is off-axis or off-power after surgery without patient dilation.


The iTrace 6 further supports physicians in diagnosing lens dysfunction with a patient-facing DLI display. The iTrace can now be used as a tool to post surgically evaluate the position of a toric lens without dilating the eyes.

Display updates in version 5 provide physicians with an easier way to navigate the vast amount of data captured by the iTrace. Surgical planning tools are first included with the iTrace.


Doctors around the world begin leveraging the power of diagnostic aberrometry in their practices as the iTrace 4 makes this superior technology accessible to all physicians.

Ray tracing is introduced to the optical industry and diagnostic aberrometry becomes the standard in the research community as the earliest version of the iTrace gains adoption.
