Instructions for Use (Continued) Risk Estimate Calculating Glaucoma The Glaucoma Risk Calculator feature provides you with a measure of the percentage of risk that a patient might develop glaucoma within the next 5 years. The risk calculation algorithm is based on the methods proposed by Medeiros, et al. (*) using risk factors identified in the Ocular Hypertension Study (OHTS).
Instructions for Use (Continued) Risk Estimate (Continued) Risk Factors Age Patient's age in years, entered manually in all cases Avg. Baseline IOP Average Baseline Intraocular Pressure. This value must be entered manually in all cases. Units are mmHg. Avg. OS,OD CCT Average Right Eye/Left Eye Central Corneal Thickness. This value is entered automatically when using the current exam measurement or a patient file from the database.
Instructions for Use (Continued) View Database To view saved entries, tap View Database on the main startup screen. You can select an examination by highlighting the examination line and tapping View, or by double tapping the examination line. Examinations are sorted by examination date – starting from the most recent.
Instructions for Use (Continued) Using the Refractive Module The Refractive Module allows data from non-central areas of the cornea to be stored in an easy and intuitive way. This feature is particularly useful for refractive procedures such as Conductive Keratoplasty. Preparation of the patient Follow the same patient preparation used when taking a standard CCT measurement.
System Menu Screen The system menu screen is accessed by touching the “Reichert Pachymetry” menu at the top and left of the screen with the stylus. When the “Reichert Pachymetry” menu is selected, the following options are shown.
System Menu Screen (Continued) Delete Database Tapping Delete Database will erase the entire database from memory, and delete all examination data. Do not perform this action if the Pachymeter’s database has not been archived by hotsyncing, unless the data is no longer needed. You may delete individual entries by entering the View Database page. Select the individual examination you would like to delete by tapping on the examination line. The examination line will be highlighted. Tap the Delete button.
System Menu Screen (Continued) IOP Reference List This screen displays the IOP Formula References screen and lists the journal articles from which the reference equations for the above pre-programmed formulas are taken. About Pachymeter This screen shows the software and firmware versions, and the device serial number. HotSync the IOPac Archive Database The database will be backed up onto a PC during each HotSync (as described in the Palm operating manual on the supplied CD ROM, and in the Appendix A).
Printer Data Printing the Examination Information Select an examination file by tapping on the examination name and make sure the printer is powered on. Point the Pachymeter infrared (IR) port towards the printer’s IR port and then tap Print. The Pachymeter’s IR port has a dispersion angle of about 90 degrees side to side and must be pointing at and within about 3 feet (1m) of the printer’s IR port. NOTE: A Canon PIXMA iP-90 printer should be used for best results.

Cleaning External Cleaning WARNING: DO NOT IMMERSE THE connector OR THE main unit in ANY liquid OR DAMAGE TO THE UNIT WILL OCCUR. Clean the external surfaces of this instrument using a clean, soft cloth moistened with a mild detergent solution (1 cc of liquid dish soap to one liter of clean, filtered water (filtered below 5 microns)).
Troubleshooting Frequently Asked Questions Q: The unit will not power up. A: Always ensure the IOPac is charged sufficiently. USE ONLY THE SUPPLIED PALM CHARGER PROVIDED WITH THE UNIT, or a USB CABLE (such as the one supplied with the IOPac) CONNECTED TO A COMPUTER. We recommend a minimum charge level of 50%. The IOPac is based on a Palm handheld computer that uses a rechargeable battery to maintain stored data and programs.
Troubleshooting (Continued) Frequently Asked Questions (Continued) Q: The calibration guide hole is dirty, how should I clean it? A: Using a Q-tip or similar soft tipped device dipped in alcohol gently swab the hole. Ensure that the flat calibration surface at the bottom of the hole is clean. Be sure not to exert excess force onto the phantom while cleaning.
General Specifications The IOPac displays thickness measurements to the nearest 1 µ m, and the expected accuracy of readings is ±5 µm over the measurement range of 300 to 1000 µ m. This assumes that the actual speed of sound in the cornea corresponds with that used in the measurements. The IOPac uses a speed of 1640 m/s, which is the most commonly accepted value for corneal tissue.

General Specifications (Continued) Tissue Exposure To Ultrasound Energy The ultrasound energy emitted by the IOPac is of low intensity and will have no adverse effects on the patient and/or operator. However, the operator is still cautioned to perform examinations using the principle of ALARA (As Low As Reasonably Achievable). All examinations should be done so that the patient receives as little ultrasound radiation as possible.
Appendix A – Installing IOPac Support on a Windows PC (HotSync) It is good practice to backup or “synchronize” files from the Pachymeter’s memory to a PC to prevent loss of data due to accidental deletion or unforeseen failures. To do this requires a PC with a Palm HotSync service. This includes a HotSync Manager, an Install Tool and an IOPac support folder to hold backup files uploaded from the Pachymeter.
The Install Wizard encourages the user to perform a first time HotSync operation after the software has been installed on the PC. New IOPac users should go through this exercise as a way of both verifying the User Name they entered and checking that the USB connection between the IOPac and the desktop computer is functioning correctly.
You should also select Skip on the following screen, as there is no additional software needed or recommended, and then select Quit to exit the installation program. 32 16012-101 Rev.
Appendix B - Procedures for Retiring a Full IOPac Database The IOPac Pachymeter examinations database, called P20Dbase.pdb, is designed to hold about 1000 examinations in memory. Given that there is more than 8 MB of memory available, database capacity is probably somewhat higher but it is difficult to estimate given the fact that other applications may also grow as the examinations database does.
Appendix C - Procedures for Reinstalling Missing IOPac Program Files IOPac Pachymeters come from the factory with all necessary pachymetry software pre-installed on the device. IOPac owners usually consider re-installing the software files on the Pachymeter for one of two reasons: To update to a newer IOPac version To recover files lost due to accidental deletion The IOPac comes from the factory with all necessary pachymetry software pre-installed in memory. To reinstate missing Pachymeter files: 1.
