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.īy identifying the origin of the aberrations through the unique analysis of lenticular vs. For the first time, eye care practitioners can truly understand, and better treat, vision complaints. With iTrace, users can objectively "see what the patient sees" with a total quality of vision assessment. 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. Additionally, general eye care specialists can use this information to select and recommend the best vision correction treatment. 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. This 5-in-1 system provides auto-refraction, corneal topography, ray tracing aberrometry, pupillometry and auto-keratometry, saving time, space and money.īy 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. The iTrace sequentially projects 256 near-infrared laser beams into the eye to measure forward aberrations, processing data point-by-point. 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. It offers easy to interpret reports, is simple to integrate, networkable and saves time, space and money. 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. The iTrace system provides repeatable measurements of the spherocylindrical refraction at near and distance, but consistency of aberrometric and optical quality measurements seems to be limited.The iTrace™ combines, auto refraction, corneal topography, auto-keratometry, wavefront aberrometry and pupillometry in one system. The Sw values for the distance and near modulation transfer function parameters were low when compared with their corresponding mean values. No significant differences between the distance and near values of Sw for the power vector components of refraction were found (p ≥ 0.08). Additionally, Sw for vertical coma was significantly larger at near (p = 0.01). However, a more pronounced variability was observed for the coefficients associated with higher order aberrations, with the poorest repeatability for the vertical coma at near, Sw of 0.011 μm for a mean value of 0.018 μm. Low values of within-subject standard deviation (Sw) were found for sphere and cylinder at distance and near and for the power vector components of refraction. Three consecutive aberrometric measurements were obtained with the iTrace system (Tracey Technologies) by an experienced examiner at distance (5 m) and near (40 cm).
All eyes achieved a best spectacle corrected visual acuity of 20/20, and had not undergone previous ocular surgeries. Bioz Stars score: 86/100, based on 1 PubMed citations.
