High-precision data for cataract and refractive surgery since 2008
Biometry
Haag-Streit optical biometers support the daily quest of the cataract and refractive surgeon and their ophthalmic technicians to provide excellent refractive results to the patient. Our Lenstar and Eyestar biometers deliver precise measurements, intuitive data representation, and latest-generation planning & analysis tools to support reliable diagnosis and surgery. Quick measurement acquisition, automation support, and ergonomic user interfaces ensure that the process of diagnostic data acquisition is pleasant for surgeon and patient alike.
