MediWorks Scansys TA517 3D Anterior Segment Analyzer

The MediWorks Scansys TA517 is a comprehensive 3D anterior segment analyzer that combines a digital infrared camera with a Scheimpflug CCD camera to generate detailed images and measurements of the cornea and anterior chamber.

The system offers 28-, 60- and 100-image scan modes, collecting up to 384,000 analysis points. A 28-image scan is completed in approximately one second, while 60- and 100-image scans require approximately two seconds. These high-density measurements generate detailed topographic, tomographic and pachymetric information for professional clinical analysis.

Scansys evaluates the anterior and posterior corneal surfaces and provides information on corneal curvature, elevation, thickness, refractive power, anterior chamber depth, chamber volume, chamber angle, pupil diameter, white-to-white distance and Kappa and Alpha angles.

Its clinical modules support keratoconus assessment, refractive surgery planning, refractive cataract surgery, IOL optimization, contact lens and orthokeratology fitting, anterior chamber angle analysis, glaucoma screening and ICRS implantation planning.

The system can generate wavefront-aberration information up to the eighth Zernike order and provide visual-quality simulations using retinal imaging, Point Spread Function and Modulation Transfer Function. Fourier analysis separates complex corneal data into spherical, decentration, regular astigmatism and irregularity components.

A growing global database of approximately 3,000 cases supports comparative analysis. The supplied workstation provides a Full HD display and dedicated Windows-based analysis software for reviewing maps, measurements and clinical reports.
