The Zeiss IOL Master V5.4 optical biometer offers fast and precise measurements
of ocular characteristics necessary for intraocular lens (IOL) power calculations.
This non-contact instrument measures of axial length, corneal curvature, anterior
chamber depth, and “white-to-white”. The easy-to-use interface clearly guides the
operator through the measuring modes and can be performed automatically with
the press of a button. The IOLMaster from Carl Zeiss sets a new standard for
highly accurate, precise measurements of all ocular characteristics necessary for
IOL power calculations. The IOLMaster from Carl Zeiss is the world’s first
instrument for the totally non-contact measurement of all data required for the
calculation of intraocular lenses. After more than ten years of clinical experience
and ongoing product enhancement, the IOLMaster is truly the Gold Standard in
biometry.

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 chamberdepth and optionally “white-to-white”. All measurements are non-contact,
providing excellent patient comfort. 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
The rapid evolution of IOL technology promises superior outcomes in cataract
surgery, and it necessarily raises the bar for pre-operative biometry. The

Certainty every time
Clinical studies have verified that the IOLMaster enables user-independent
measuring results. These studies1) have also shown that considerably higher
reproducibility is obtained than with ultrasound.
State of accommodation, pupil diameter and high ametropia do not influence the
measured axial length. Optical biometry along the visual axis ensures precise
measurements, particularly for problematic eyes;
Printout of the measuring report
staphylomatous and pseudophakic patients, silicone- filled eyes and eyes with
phakic implants are easy to measure thanks to different measuring modes. The
Haigis-L formula can be used without difficulty to cal- culate lenses for eyes
subsequent to refractive corneal surgery for the correction of myopia and
hyperopia. The corneal refractive power can also be calculated using the patient’s
refractive history or contact lens overrefraction.
Calculating phakic implants the easy wayThe calculation of phakic intraocular lenses is also pos- sible with the IOLMaster.
For fast, simple measurement of the power of phakic anterior and posterior
chamber IOL, the appropriate lens constants are already con- tained in the
system software.
Selection couldn‘t be easier
An integrated, freely configurable database enables fast and easy lens selection.
The optimization func- tion automatically calculates the individualized lens
constants which more effectively meet your personal requirements. As starting
values, pre-optimized con- stants from more than 100 of the most commonly
used IOL types can be loaded into the system. For the optimization of these
constants, the ULIB2) has already collected more than 20,000
