    Instructions for Use (Continued) Start Measuring Central Corneal Thickness (CCT) Measurement Preparation of the Patient The patient should be in a seated position. It may be helpful to explain that they should relax and attempt not to blink as the probe is going to gently contact their eye. A drop of ocular anesthetic should be placed in the eye or eyes that are going to be measured.

This will cause damage to the probe and void the IOPac warranty. The Measuring screen shows both the right (OD) and left (OS) eyes. The instrument will default to the right (OD) eye. You can switch the eye that you want to measure by tapping either the OD or OS box at the top of the screen.

    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)).

  • Page 25: Troubleshooting

    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%.
  • Page 26 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. Q: Why does the unit display a reading when not in contact with the patient's eye? A: If the tip of the probe is wet, the unit will measure the thickness of the drop of water on the tip.

  • Page 27: General Specifications

    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.

    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).

  • Page 30: Appendix A - Installing Iopac Support On A Windows Pc (Hotsync)

    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.
  • Page 31 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.

  • Page 33: Appendix B - Procedures For Retiring A Full Iopac Database

    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.

  • Page 34: Appendix C - Procedures For Reinstalling Missing Iopac Program Files

    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.
