This very sophisticated data develops a personalized treatment plan unique to your eyes.
The iDesign uses wavefront aberrometry to create a customized mapping of your cornea.

This technology was the first FDA-approved, fully automated, non-contact method of alignment and registration for your customized iDesign ™ treatment. This is a vital instrument for complex cases. The high-resolution images and precise measurements from the PENTACAM® Corneal Tomography help surgeons identify any concerns with the cornea and substantiate surgical planning. The PENTACAM® Corneal Tomography provides three-dimensional images of the entire anterior eye segment. The CIRRUS™ HD OCT includes anterior imaging of the eye and provides valuable thickness measurements of the cornea. An optical coherence tomography (OCT) scan will lead to greater patient outcomes by providing high-resolution images of the retina. The LENSTAR LS 900® offers the best technology in IOL calculations and provides surgeons with the utmost confidence as the optimal planning platform for toric and premium IOLs.ĬIRRUS™ HD OCT Optical Coherence TomographyĪ proper retinal evaluation pre-surgery is imperative to prevent any visual surprises post-surgery. These measurements are critical for the selection of the correct IOL power to achieve superior refractive outcomes in cataract surgery. Following pupil dilation, aberrations were measured with the iTrace and OPD Scan. Methods: A total of 54 healthy eyes were enrolled in the study. The LENSTAR LS 900® provides highly accurate laser optic measurements for every section of the eye (from the cornea to the retina). Purpose: To compare and evaluate the total and internal aberrations measured by two aberrometers: the laser ray tracing aberrometer (iTrace, Tracey Technology) and the automatic retinoscope aberrometer (OPD Scan, Nidek). This provides a better understanding of the patient’s vision and the structures affecting it therefore increasing the confidence for your custom treatment plan. This novel device offers highly accurate information by identifying the origin of aberrations (i.e., cornea or lens). The iTrace™ allows the surgeons to "see what the patient sees" by providing a total quality of vision assessment. Our state-of-the-art centre is equipped with only the best.Ĭarefully curated and handpicked by our surgeons, each instrument is considered the “Gold Standard” in its field to ensure a comfortable experience for our patients while providing thorough information for planning and executing your procedure to the highest standard. The completed devices are shipped world wide as the Tracey Technologies iTrace Combination Ray Tracing Aberrometer/Topographers.All of the Barrie LASIK Centre’s diagnostic instruments provide rich data and information about your eyes and are essential to achieve the best possible outcomes for your procedure. We currently manufacture the electronics under an OEM agreement with Tracey Technologies.
#Itrace abberometer software#
Indus Instruments developed the electronics and the low level software for three generations of these ray tracing devices over a 10 year period. 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). 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. Visual outcomes were determined by Post-operative refraction, Uncorrected Visual Acuity and aberrometry estimated with iTrace aberrometer post operatively. Modern laser technologies enable a more finely controlled cornea reshaping with an array of points of varying corrections across the eye. Conventional means of sight correction, like glasses or contact lenses, deal with global parameters of eye refraction.
