he 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 chamber depth 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.

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 way
The calculation of phakic intraocular lenses is also possible with the IOLMaster. For fast, simple measurement of the power of phakic anterior and posterior chamber IOL, the appropriate lens constants are already contained in the system software.
Selection couldn‘t be easier
An integrated, freely configurable database enables fast and easy lens selection. The optimization purpose automatically calculates the individualized lens constants which more effectively exceed 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
