ZEISS optical biometers Defining biometry for 20 years
20 years ago, ZEISS introduced the first optical biometer and revolutionized IOL power calculations. Since then IOLMaster® biometers from ZEISS have become the most commonly used biometers in the ophthalmic world with more than 150 million IOL power calculations to date.
Defining biometry
for 20 years
labor hours has the ZEISS development team spent on the IOLMaster over the past 20 years.
is the cataract penetration rate of the latest optical biometer the ZEISS IOLMaster 700.
IOL power calculations have been performed using a ZEISS IOLMaster.
