Please read the Operator's Manual in its entirety before using your Tracey iTrace System.
Welcome New User Congratulations on acquiring your new iTrace Visual Function Analyzer (iTrace). Chapter 2 acquaints you with your system’s hardware: the data acquisition unit (DAU) and the computer. Chapter 3 covers the basics of using your system, from powering on and off to using your iTrace software and working with the screens. Chapter 4 of this manual reviews how to manage new and existing patients. Chapter 5 details how to examine patients and Chapter 6 explains how to review the exam data. With your new iTrace, you will now have the ability to look at the entire refraction of the eye with the highest level of objective measure and detail. In fact, viewing a refractive map of the entrance pupil which covers the refractive power of the entire eye on a point-by-point basis, as opposed to the basic refractive numeric summary of sphere and cylinder, will have an enormous impact on your practice in terms of speed, accuracy and the clinical care of your patients. To measure refraction on a spatially resolved basis requires the ability to look at the wavefront aberrations of the eye on a point-by-point basis. The iTrace actually analyzes light that is directed into the eye focused onto the retina creating a secondary light source as it is reflected from the retinal surface and projected out the exit pupil. The iTrace uses the fundamental thin beam principle of optical ray tracing to measure the refractive power of the eye on a point-by-point basis. The simplicity of measuring one point in the entrance pupil at a time is unique to the Tracey system. Your iTrace system is designed to very rapidly fire a series of very small parallel light beams one at a time, within microseconds into the entrance pupil. These beams of light pass through the entrance pupil of the eye in an infinite selection of software selectable patterns. With new designs of the photo detector system, iTrace can easily measure a large dynamic range of aberrations and maintain high resolution. This should provide for a significant advantage when measuring a physiologic system, such as the eye, which can easily have a tremendous range of refractive errors. Additionally, since each point is sequentially measured there is never any confusion of which entrance pupil location registers with the retinal spot detected. As the iTrace system directly measures the point spread function of the eye with its retinal spot detection, it can then easily provide for full calculation of wavefront deformation of the eye.
Your iTrace system also captures and processes corneal topography data. Wavefront data of the cornea is combined with wavefront data of the eye to obtain the lenticular aberration analysis.

Chapter 2 Getting to Know Your System The Tracey iTrace Visual Function Analyzer provides the ability to offer your patients accurate, repeatable, and prompt refractive measurements of the complete optical system in the eye. The iTrace performs these primary tasks: • Captures an eye image • Measures 256 points within the patient's entrance pupil • Generates numerous customized displays to view the data • Saves exam data in an organized database • Automatically centers, sizes the scan pattern within the pupil, and captures the data • Verifies focus and alignment • Prints any of the provided displays • Saves displays as bitmap files • Combines corneal wavefront data and total eye wavefront data to generate a lenticular aberration analysis. The system also has provisions for these functions: • Displaying and analyzing exam data in user-defined custom formats • Setting and changing system parameters • Patient database management This chapter describes the primary components of your system: the Data Acquisition Unit, the external computer, and the data storage recommendation. Chapter 3 discusses the basics of using your system, and navigating around the menus.
Data Acquisition Unit - DAU This is the main component of the iTrace VFA system. It is used to project and record the points of light as they enter through the pupil and focus on the retina. The iTrace software uses these data points to produce the various displays. The Data Acquisition Unit (DAU) features an adjustable focusing target, pupil size detector, and an OD/OS detector. It also features a Placido-based corneal topography analyzer. The backlighted Placido rings are projected onto the corneal tear film, and the 13
Getting to Know Your System
image is auto-captured when device is at the proper working distance and the projected laser beam is centered in the live video image. The iTrace software then defines the ring edges and calculates corneal curvature, corneal refractive power, and corneal wavefront data. The DAU also contains an internal optometer. The optometer is the fixation device for alignment of the patient’s line of sight with the laser axis. It also serves to relax the patient’s accommodation by providing a target of increasing/decreasing spherical correction from +7D to -5D primarily. Additionally, the DAU contains the power supply, data transmission and image capture processing boards. This unit is NOT SERVICEABLE by the customer, and only trained Tracey service engineers should open and service this component due to possible exposure to hazardous laser radiation.
Cleaning and Maintenance The iTrace chin rest, forehead strap, handles and any other part of the device which comes into contact with the patient should be cleaned thoroughly before use and between patient usage with isopropyl alcohol disinfecting wipes using light pressure. The exterior of these units, other than those listed above, may be cleaned with a dry cloth or antimicrobial dry wipes. Avoid getting any moisture or liquid on/in the system. DO NOT touch the optics inside the eyepiece. If necessary, compressed air may be used to remove dust inside the optical eyepiece. BEFORE using the air, power the system off. To properly maintain your iTrace Visual Function Analyzer, the user should check the device’s calibration periodically. Please refer to the steps in Chapter 4, To Perform a Quick Calibration Check, page 33.

To Select or Change the Storage Location for Your Patient Data By default, your patient data is stored within Microsoft Jet databases that are located in a folder titled Data within the Tracey folder of your computer’s hard drive. You have the option of creating a network accessible database folder with the iTrace software. Storing your patient data on a network accessible drive will allow you and others to view the data from any computer on the network that is running the iTrace software. For more information, see Appendix F. You can also create multiple databases. To change the location of your database or create a new database, follow these steps: 1. Click CTRL + D. The following dialog box will appear. 2. Click the radio button labeled “Microsoft Jet”. 3. In the box, type in the folder address for the new database location or click Browse… to locate and select it. 4. Click OK. The iTrace software will store your patient data in this new database until you return to this screen and select another database. 5. If this software installation is on a network and is for viewing patient data only (i.e. it is not connected to the iTrace DAU), click on the check box next to Open as readonly. This will tell the software that this software instance will not be saving to the database and will not interfere with the database access sequence. If the Read-only checkbox is not checked, the clinic must take care to ensure that the software connected to the iTrace DAU is always the first software to access the database. Therefore using the checkbox is highly recommended. Note: Please consult with your network administrator before creating a database on a network drive. It is the user’s responsibility to ensure the integrity of their data on a network.
