The Analysis Advantage

MS-39 combines Placido disc corneal topography with high-resolution OCT-based tomography for the most advanced analysis of the anterior segment


Understanding the lay of the land is a key part of planning and, ultimately, success. Although this process requires expertise and discernment on the part of a practitioner, having the right tools within the ophthalmologist’s toolkit makes it easier to get the job done, and done well. C.S.O is dedicated to offering eye care practitioners the best diagnostic ophthalmic instruments, and with MS-39, the company presents practitioners with the most advanced all-in-one device for the analysis of the anterior segment of the eye.

As a leading ophthalmic device, MS-39 harnesses highresolution, spectral domain optical coherence tomography (SD-OCT) technology. It allows for detailed analysis of the curvature, elevation, refractive power and thickness of multiple layers of the cornea, including the epithelium, Bowman membrane, and stroma, with a resolution of 3.6 μm in tissue. Compared to Scheimpflug technology, OCT technology is less affected by the scattering of opaque tissues, making the maps of irregular and pathologic corneas generated with MS-39 more reliable than those created with Scheimpflug based devices. Additionally, MS-39 uses Placido disc technology, which provides the highest accuracy for measuring the anterior corneal surface curvature, elevation, and refractive power. Through Placido disc corneal topography, MS-39 is also able to provide tear film break-up time analysis.

The MS-39’s combination of these two innovative technologies gives clinicians unparalleled insight and clarity into the anterior segment structures through 16 mm diameter cross-sectional images – something appreciated by anterior segment specialists. Further, the device provides access to exam information through its collation into well-packaged diagnostic summaries, ensuring that users can obtain the data that they need when they need it. Beyond anterior segment clinical diagnostics, MS-39 can also be used in corneal surgery for refractive surgery planning by enabling the earlier detection of keratoconus, thus improving patient selection. Moreover, the device’s Ray-Tracing-based IOL calculation module is helpful for approaching candidates for cataract surgery who have previously undergone refractive treatments. MS-39’s additional tools allow it to perform advanced analysis of the tear film and accurate pupil diameter measurements.

Ultimately, the MS-39 is designed to give anterior segment specialists the most accurate view of their ocular surroundings, so that they can make the most informed decisions and achieve the highest levels of success for their patients.
