Haag-Streit Biometers: Eyestar 900 and Lenstar 900

The Eyestar 900 features swept-source technology, enabling precise measurement, as well as topographic assessment, of the front and back corneal surface and the anterior chamber, including the lens, as well as imaging of all these structures. It also includes cornea-to-retina biometry of the entire eye. The Eyestar 900 uses the Mandala Scan technology with OCT motion compensation, independent of any video-based eye-tracking. The system provides OCT biometry of the entire eye, OCT topography, Zernike analysis with vision simulation, and a reflective dual-zone keratometry. The Lenstar optical biometer features laser interferometry biometry of the entire eye from the cornea to the retina with measurements of all the segments of the human eye, including the corneal thickness, anterior chamber depth, lens thickness, and axial length.
