Manufacturer: Tracey Technologies
Product code: ITRACE

Measures both lower and higher order ocular aberrations, assessing complete visual function and quality of vision

iTrace_laptop_table_nobck LR.jpg

The iTrace™ combines, auto refraction, corneal topography, auto-keratometry, wavefront aberrometry and pupillometry in one system.

Visual analysis is not based only on sphere, and cylinder – iTrace offers an objective perspective of the complete visual pathway, analyzing aberrations from low to high order. It offers easy to interpret reports, is simple to integrate, networkable and saves time, space and money.

The iTrace measures quality of vision and visual function using a fundamental thin beam principle of optical ray tracing, a first in eye care diagnostics.  The iTrace sequentially projects 256 near-infrared laser beams into the eye to measure forward aberrations, processing data point-by-point. This 5-in-1 system provides auto-refraction, corneal topography, ray tracing aberrometry, pupillometry and auto-keratometry, saving time, space and money.

By integrating wavefront aberrometry with corneal topography, the iTrace provides a unique analysis that subtracts corneal from total aberrations in order to isolate the internal aberrations of the eye.  Surgeons benefit from this information when planning surgical procedures such as refractive lensectomies, AK's, Accommodative and Multifocal IOL's and for post-op evaluations.  Additionally, general eye care specialists can use this information to select and recommend the best vision correction treatment. You can also have better information about the patient's optical system's alignment so that you can decide which IOL is best for the patient.

Optical Alignment

Know if a patient's optical system will align with a multi-focal before you do surgery. Do the right procedure on the right patient.


Separate Cornea and Lens

Understand the source of the aberrations to diagnose Dysfunctional Lens Syndrome and determine candidacy for premium IOL options.


Toric Check

Post-op toric surprises can and do happen. What used to be a time consuming, uncomfortable process for surgeons and patients to determine post-op axis location is now a 30 second iTrace exam with NO DILATION! Know if a toric IOL is off-axis or off-power and understand the change to the BCVA that is likely with a lens rotation.


With iTrace, users can objectively "see what the patient sees" with a total quality of vision assessment. For the first time, eye care practitioners can truly understand, and better treat, vision complaints.


The iTrace can increase users' confidence in vision analysis, even in difficult cases, with its highly accurate, state-of-the-art diagnostic information; improving efficiencies, saving time and avoiding mistakes.


By identifying the origin of the aberrations through the unique analysis of lenticular vs. corneal aberrations, users have more information and a better understanding of patient's vision and the structures affecting it and therefore can make better treatment decisions.
