OCT Anterior


The most advanced device for the analysis of the anterior segment of the eye. MS-39 combines Placido disk corneal topography, with high resolution OCT-based anterior segment tomography. The clarity of the cross-sectional images, with a 16 mm diameter, along with the many details of the cornea structure and layers revealed by the MS-39, will be appreciated by  anterior segment specialists. MS-39 provides information on pachymetry, elevation, curvature and dioptric power of both corneal sufaces.

In addition to anterior segment clinical diagnostics, MS-39 can be used in corneal surgery for refractive surgery planning. An IOL calculation module is also available, based on Ray-Tracing techniques, Additional tools allow MS-39 to perform accurate pupil diameter measuremets and the advanced analysis of tear film.

With the Eyestar 900, Haag-Streit is opening a new chapter in measuring, imaging and diagnosing the human eye with the introduction of a complete swept-source OCT-based eye analyser. 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.

Imaging of the entire anterior chamber, including the crystalline lens, allows the user to easily verify any measurement and to identify anatomical anomalies that may interfere with planned surgical procedures. Topographic maps of the anterior and posterior cornea and pachymetry maps enable users to improve their surgical plan and review patients’ suitability for specific interventions, such as toric- or multifocal IOL.
