iTrace Wavefront Aberrometer

iTrace is the only device on the market to use ray tracing aberrometry and placido-based corneal topography to map the sources of errors in the eye and provide a simulation of a patient’s vision.

iTrace Wavefront Aborometer

The iTrace uses ray tracing aberrometry and placido-based corneal topography. It is the only device on the market to map the sources of errors in the eye and provide a simulation of a patient’s vision.

iTrace is a 5-in-1 device developed to support clinicians with ophthalmic diagnosis and surgical correction of vision.

iTrace displays the full visual function of a patient’s eye with a simple scan. It can be used as a standalone wavefront aberrometer, autorefractor, keratometer, pupillometer, or corneal topographer.

iTrace proprietary technology is the only device to accurately scan a post-operative patient’s vision.

Patented ray-tracing technology truly separates the visual function of a patient’s cornea from their internal optics. Gain improved understanding of how the structures affect a patient’s vision. Use this additional information to make precise treatment decisions.
With iTrace’s proprietary software, you can access a series of images to demonstrate how a patient’s visual function breaks down. This patient-facing display makes it easy to understand what a dysfunctional lens diagnosis means before learning about treatment options.
Offers surgeons an integrated toric calculator that utilises the advanced iTrace Keratometry readings. Using markers in the natural structure of the eye, the portable map guides precise placement of any Toric lens. Use the iTrace’s Toric Check functionality in post-surgical evaluation to verify accurate lens placement or confirm off-axis or off-power results and provide optimal lens rotation without dilating a patient’s eyes.
Associated picture display allows patients to confirm that the iTrace assessment is an accurate simulation of their vision with widely recognised Snellen E. When recommending a lens replacement, use the display to simulate the toric and standard lens difference in a patient’s post-surgical vision. Educate your patients about their treatment options and communicate the value of a premium cataract procedure.
The user-friendly iTrace displays are a powerful way to show patients the difference between a standard and an upgraded lens. By depicting blurred versus clear versions of the Snellen E, iTrace enables a common language between surgeons and patients. In the click of a button, demonstrate to a patient with astigmatism what their post-surgical uncorrected vision looks like with or without a toric lens.
A post-operative scan in just 30-seconds evaluates the post-operative alignment of a toric lens without dilation. Determining the post-operative axis location is a quick and comfortable. The iTrace calculates cross cylinder and verifies whether a toric IOL is off-axis or off-power.
iTrace Wavefront Aberrometer benefits
  • Identify and map higher and lower order aberrations throughout the anterior segment.
  • Assess progression of corneal and lens dysfunction.
  • Understand exactly how these errors affect your patients’ visual performance.
  • Track the exact source of any vision issues.
  • Objectively quantify vision loss over time and helps patients understand their eyesight.
  • Precise calculation of higher and lower order aberrations.
It’s the best way to ensure precision during surgery.

iTrace’s superior information and diagnostic tools make it easy to provide the best possible outcomes from surgery.

iTrace’s  Toric Planner uses precise wavefront Ks, optical alignment angles, and printable pictures to achieve ideal lens placement during surgery. Plus, the Toric Check provides post-operative guidance on toric axis location without the need for dilation.

iTrace Ray Tracing uses a sequential series of infrared beams on the order of 100 microns and a 785 nm wavelength each is projected into the entrance pupil parallel to the eye's line of sight.

It’s a measure of aberropia. As light passes through the irregularities of an actual imperfect eye, light diverges from its ideal wave-front resulting in angle deviation.

iTrace technology analyses aberrometry, performs clinical topography and provides visual function of the human optical system.

It is useful in refractive lensectomies and dysfunctional lens syndrome. It is also useful for aspheric, accommodative, multifocal and toric IOLs and for postop evaluation. Improved information of the patient’s optical system’s alignment is necessary to enable you to decide which IOL is best for your patient.

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.

Clinicians can use this information to select and recommend the best vision correction treatment.

Ray Tracing technology is a patent of Tracey Technologies. iTrace is the only device to use ray tracing for wavefront analysis. iTrace sequentially projects 256 parallel light rays through the entrance of the pupil and detects where each beam of light lands on the retina and, how much light energy is transferred. Assessing this retinal spot pattern provides insight into a patient’s overall visual function.

Similar devices rely on a Hartmann-Shack sensor or dynamic skiascopy for wavefront imaging, where light as it is reflected back from the retina. This works for simple optical systems however, these devices are prone to data confusion when measuring highly aberrated eyes, pseudophakia, with cataracts, through contact lenses, or over spectacles.

Only iTrace and its proprietary ray tracing technology can directly replicate a patient’s vision under any circumstance.

Only iTrace has the ability to give insight into both the form and function of the eye. By integrating wavefront aberrometry with corneal topography, iTrace can objectively map the internal optics of the eye by subtracting corneal from total aberrations. In less than a minute, iTrace generates a complete profile on a patient’s topography, wavefront, autorefraction, keratometry, day to night vision, pupillometry, white to white and more.
