Key Benefits

The MS-39 anterior segment topographer-tomographer is a fast acquisition system that captures high-resolution images of the ocular anterior segment and accurately measures various clinically interesting ocular structures (eg, anterior and posterior corneal surface, anterior chamber, pupil diameter). The measurements are based on the integration of three of the most advanced technologies including spectral domain OCT, Placido disc and infrared pupillography.

The Zeus MS-39 offers more details than traditional Scheimpflug cameras, featuring 12 different corneal maps including epithelium thickness map. It also features IOL calculation (state-of-the-art ray tracing), keratoconus and glaucoma screening, pupillography, lens biometry, non-invasive tear break-up time (NIBUT) and infrared Meibography.
