![]() Using the iTrace it is possible to conduct ones own independent study and determine an accommodative IOLs true performance. The examiner can vary the pupil analysis in order to maintain consistency for comparison. The completed devices are shipped world wide as the Tracey Technologies iTrace Combination Ray Tracing Aberrometer/Topographers. The iTrace will measure and record the scan size of the pupil during distance and near testing. Tracey itrace technology enables the trace users o objectively see what the patients see with a total quality visual assessment. While the iTrace can certainly be used as a standalone wavefront aberrometer, autorefractor, keratometer, pupillometer, or corneal topographer, leveraging the combined picture of these individual measurements in your office can improve surgical outcomes and patient satisfaction. We currently manufacture the electronics under an OEM agreement with Tracey Technologies. Tracey iTrace Combines autorefraction, corneal topography, auto-keratometry, wavefront aberrometry, and pupillometry in one system. His team created an integrated wavefront aberrometer and corneal topographer designed to objectively measure vision in any patient. Indus Instruments developed the electronics and the low level software for three generations of these ray tracing devices over a 10 year period. The iTrace Ray Tracing Aberrometer/Topographer is a 5-in-1 system that provides auto-refraction, corneal topography, ray tracing aberrometry, pupillometry and auto-keratometry. About a hundred such measurements are made across the eye in a fraction of a second and the data is used to compute the refractive index map of the eye.Ī novel feature of this instrument is the acousto-optic deflector that moves the laser beam across the eye without the use any moving parts. To accomplish this a low power infrared laser beam is sent into the eye and the deviation of position of the reflection from the retinal surface from the ideal position is measured to an accuracy within 2 microns (10^-6 meters). Request PDF Repeatability and Agreement of Wavefront aberrations of Pentacam AXL Wave- a new hybrid topographer and aberrometer with ITrace in healthy eyes Purpose: To assess repeatability and. One of our customers, Tracey Technologies, Houston, TX, came up with the idea for a single beam refractometer based on retina ray tracing for measuring eye refraction distribution. These laser-based vision correction methods require accurate local parameter information across the eye to enable correction that achieves higher visual acuity. By integrating wavefront aberrometry with Placido disk corneal topography, the iTrace Combination Ray Tracing Aberrometer/ Topographer provides an analysis. ![]() Modern laser technologies enable a more finely controlled cornea reshaping with an array of points of varying corrections across the eye. This 5-in-1 system provides auto-refraction, corneal. Conventional means of sight correction, like glasses or contact lenses, deal with global parameters of eye refraction. The iTrace sequentially projects 256 near-infrared laser beams into the eye to measure forward aberrations, processing data point-by-point.
