The iTrace vs. Marco OPD III
The iTrace does everything better using proprietary Ray Tracing technology, giving doctors the most complete information about a patient’s vision.
The iTrace Is Beyond Compare
During An Exam
The iTrace helps you see what your patient is seeing with its proprietary output, the iTrace Dysfunctional Lens Index. This user-friendly readout helps you identify the source of errors in your patients’ vision between the cornea and the lens.
Before Surgery
Using the iTrace, you can decide if either refractive surgery or lens replacement is the right next step in a given case. If a lens procedure is your choice, iTrace tools such as the Toric Planner and Osher Ring can improve precision in toric surgery.
After Surgery
After surgery, the iTrace’s Toric Alignment Check tool can give you a clear indication of the final position of a toric lens without the need for dilation. The OPD III cannot do this and instead encourages dilation and a retroillumination image.

Comparing the Technology: iTrace vs. OPD III
The iTrace and the OPD III are NOT the same… especially where it matters most. In a direct comparison between the iTrace’s Ray Tracing technology and the dynamic skiascopy used by the OPD III, researchers have found that the OPD has a tendency to “miss” higher order aberrations in a patient’s vision — a critical error that may affect the outcome of surgery.
How We Compare
Like the iTrace, the OPD combines wavefront aberrometry and topography in a single device. But how similar are the iTrace and the OPD III really? While both operate with a placido disk-based topographic system, the iTrace’s use of property ray tracing for diagnostic aberrometry translate into the following advantages.

So why does the iTrace stand out in the industry? Early on, it was embraced as a research tool due to its ability to measure vision in the most precise and repeatable ways. Over time, it evolved into what it is today — a practical system for ophthalmologists and eye care practitioners to leverage the best technology on the market in ways that improve outcomes for their patients.
