Is 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.
