Optical biometers from ZEISS
A success story with more than 100 million IOL power calculations to date
Almost 20 years ago, ZEISS introduced the first optical biometer and revolutionized IOL power calculations. Since then IOLMaster® biometers have become the most commonly used biometers in the ophththalmic world with more than 100 million IOL power calculations to date. After introducing and continually improving PCI for biometry measurements, ZEISS launched its first SWEPT Source OCT-based biometer in 2014. Continuing to innovate on this platform, ZEISS just introduced Total Keratometry and is already working on the next innovations to remain the leader in optical biometry.
