– Position the printer at least 1.5 m from the patient’s seat at the
device.
– The user should not simultaneously touch the patient and metal
parts of the printer.
– If a Protection Class II printer (without protective earth terminal) is
used, make sure that a power isolation transformer (see page
19)
is connected into the printer power supply cable.
– If a Protection Class I printer (with protective earth 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
19) is connected into the printer
power line.
– The required isolation transformer can be obtained from our sales
organisation.
– 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

Description
Intended use of the device
The device is to be used only for the measurement of axial length,
corneal radii, anterior chamber depth and optionally for the
determination of "white-to-white" of the human eye, as well as for the
calculation of the required intraocular lens. Responsibility for using the
device other than as intended lies with the user.
The device may only be used in combination with accessories delivered
by Carl Zeiss Meditec (see Section
Please consult Carl Zeiss Service regarding the use of other accessories.
Functional description
The IOLMaster is a combined biometry device for measurements on the
human eye required for the preoperative computation of intraocular
lens power.
It is capable of fast and precise consecutive measurement of the
following eye parameters in one session: axial length, corneal curvature,
anterior chamber depth and optionally "white-to-white". All
measurements are non-contact, providing excellent patient comfort.
Optional accessories on page 18).
15
The axial length measurement is based on a patented interference
optical method known as partial coherence interferometry (PCI). The
displayed results of the axial length measurements are compatible with
the ultrasonic immersion measurements of axial length via the use of an
internal, statistically verified calculation algorithm. The familiar formulae
for IOL calculation can thus be used.
However, the lens constants must be changed for use with the PCI
method. Please consult the scientific literature on this subject.
The corneal curvature is determined by measuring the distance between
reflected light images projected onto the cornea.
The anterior chamber depth is determined as the distance between the
optical sections of the crystalline lens and the cornea produced by
lateral slit illumination.
"White-to-white" is determined from the image of the iris.
The individual measurement procedures are automated, so that the
operator is only required to adjust the device to the patient’s eye and
initiate the measurement. For this reason the complex biometry of the
eye can be rapidly learnt with the IOLMaster, but should be practised
with the greatest of care and attention to detail.
Extensive integrated safety features (independent redundant hard and
software safety features) ensure maximum safety for both the patient
and operator when using the IOLMaster.
The control program for the computer in the device base runs under
Windows. A backlit LCD serves to observe the patient’s eye and display

the readings. The device is controlled by the joystick and computer
keyboard with integrated touchpad.
Based on the readings, the program can make suggestions for the
choice of intraocular lens strengths. The latter are based on
internationally accepted calculation formulae. The Haigis, HofferQ,

The Haigis-L formula may be used to calculate IOLs after
LASIK/PRK/LASEK.

An IOL database is likewise implemented. Prior to calculation, the latter
must be filled with data for the desired lens.
On the basis of postoperative refraction results, the lens constants
entered into the calculation formulae may be optimised (personalised)
for each individual user.

Operation
General notes on control
The operating system of the device's control computer works in the
background. For safety reasons, it is not accessible to the user.
Warning
All attempts to manipulate the operating system are strictly prohibited!
In particular, deactivation of the Windows firewall is not permitted!
Windows operating conventions apply analogously to the user interface
of the IOLMaster software. This relates to working with a
mouse/touchpad, the use of icons, working with dialog boxes and
menus, confirmation by double-click, etc.
Note
The system does not support all key combinations of Windows.
The special Windows keys that exist on some keyboards are
ineffective.
The software uses only a few forced processes. The user may switch
freely between the individual modes. For rational working the user is
urgently advised to observe the sequence of measurements described
from page
In rare cases, Windows error messages may appear on the LC display.
This might be the case, for instance, if the program running is affected
(mostly by external disturbances).
Multiple safety mechanisms in the instrument’s hardware and software
ensure that there is no risk of injury.
Caution
If warning messages appear frequently, the device should be taken out
of service and labelled as such. Then call Carl Zeiss Service.
The device does not support the submission of automatically generated
problem reports to Microsoft!
The device may be operated by:
using the icons (by cursor, touchpad) or
keyboard or
menus.
53 onwards.
Measurements are initiated by pressing the button on the joystick.
