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 to provide excellent outcomes for their patients. Both Lenstar and Eyestar biometers deliver high-precision measurements and their simplicity allows them to be operated by all eye care professionals. The Eyestar delivers all-in-one biometry; precise AL measurement, keratometry, topography, and pachymetry. Eyesuite software boasts modern formulae to support with diagnosis and surgical planning.
