ZEISS IOL Master 500

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
