  • Consult before using older printers to determine whether printer drivers compatible with the Windows®XP operating system are available and use these.
  • Position the printer must always be positioned outside the range of the patient (1.5 m from the patient’s seat at the device).
  • The operator should not simultaneously touch the patient and metal parts of the printer.
  • If a Protection Class II printer (without protective ground terminal) is used, make sure that a power isolation transformer (see page 17 of the IOL Master Instruction Manual V.5) is connected to the printer power supply cable.
  • Protection Class II printers (without protective ground terminal) whose wattage (power consumption) exceeds the permissible connected load of the power isolation transformer may not be used.
  • If a Protection Class I printer (with protective ground terminal) is used, make sure that it is connected to its own stationary wall socket of the room's electrical installation or that a power isolation transformer (see page 17 of the IOL Master Instruction Manual V.5) is connected into the printer power line. The required isolation transformer can be obtained from Carl Zeiss Meditec.
  • The power isolation transformer may not be used for printers whose wattage (power consumption) exceeds the permissible connected load of the power isolation transformer (e.g. laser printers).
IOL Master Warning Symbol   Electrical Safety
  • Additional portable multiple sockets or extension cords may not to be used.
  • The electrical supply used with the IOLMaster must conform to IEC 60364-7-710 guidelines. USA and Canada only: single-phase 120 V AC connections with plug type NEMA 5-15P.
  • During use of the IOLMaster, do not use a cellular telephone and other devices not complying with EMC Class B requirements, as its signals may cause the IOLMaster to malfunction. The effect of radio signals on the IOLMaster is dependent on various factors and is therefore not predictable. To avoid electromagnetic interference, the IOLMaster must be installed and operated as described in the IOL Master Instruction Manual V.5 and using only those components supplied by Carl Zeiss Meditec.
  • With the exception of compatible printer drivers, the installation of other software onto the IOLMaster is not permitted. The IOLMaster software is programmed to prevent external (third party) software from being installed on the system.
  • The IOL Master may only be connected to private networks that are protected from public networks (Internet) by firewalls conforming to the latest technical standards. Such actions will render any warranty claims invalid.
  • The built-in power supply unit of the IOLMaster is short-circuit-proof, and does not contain any fuses accessible from the outside.
  • Provided the IOLMaster is properly used, no electrical hazards exist to either patients or operators.
  • Only service technicians authorized by Carl Zeiss Meditec may open or setup the IOLMaster.
Requirements for operation

  • Use the power cable supplied with the IOLMaster. If the IOLMaster is mounted on an IT3L instrument table, it will receive its power supply through the table.
  • The main power supply plug of the IOLMaster must be inserted into a power outlet that has an intact protective conductor connection.
  • All cables and plugs may be used only if they are in perfect working condition. In particular, the spring action plug for the IOLMaster control must remain plugged in and should not be pulled out.
  • If the ground contact is impaired, or if electrical wiring is damaged, the IOLMaster must be taken out of service and measures taken to prevent inadvertent use. Following this, call:

    Carl Zeiss Meditec Service

  • Do not cover/obstruct ventilation slots in the computer casing (right and left).
  • If peripheral devices are connected (CRT monitor and/or PC are possible) the user must ensure that safety requirements of DIN EN 60601-1-1 (medical electrical systems) are observed.
  • A network isolator can be ordered from Carl Zeiss Meditec for connection to an external network (NET).
  • If either of the error messages "Laser adjustment too high" or "Laser measurement power too high, measurement aborted" appears, the IOLMaster must be shut down Following this, call Carl Zeiss Meditec Service.
  • Disconnect the power cable immediately if damage or unspecified problems occur.

Light emission from the IOLMaster

  • The limit values as specified for Class 1 laser devices to EN 60825-1 will be observed if the IOLMaster is operated as intended.

Proper Shut Down Procedure

  • Always enter the patient data (last and first name, date of birth) or ID No. (depending on setting in Setup menu).
  • Pull the power supply cable immediately if damage or unspecified problems occur!
  • Switch off the device as follows:
    • Click on the EXIT icon on the toolbar (shown above) or <E> key..
    • Confirm with OK or <ENTER>.
    • When the "It's now safe to turn off" message appears, turn the IOLMaster off by the main power switch. The program will automatically close; the readings for the last patient will be saved and the IOLMaster will shut down automatically (lamp in the switch goes off).
Optical Coherence Biometry

IMPORTANT: For as long as the switch lamp is lit, internal components are still under voltage, even after the device has been switched off at the power switch!

All-pole disconnection of the device has not been achieved until the switch lamp goes off. The lamp must be off before the power supply is unplugged or the device switched off at the main room switch. Failure to observe these instructions may result in loss of data.

To completely disconnect from the power supply the IOLMaster must be unplugged. The power cable should not be pulled or the main switch of the room installation activated until the screen is blank.

The device may not be switched on again until the switch lamp goes off!

The procedure described above does not apply in the case of breakdowns or if the device does not respond to your input. If this occurs, switch off the device immediately and pull the power supply plug. Label the device as being defective and call Carl Zeiss Service.
