Sirius+

Sirius+ integrates Placido-disk topography with Scheimpflug anterior-segment tomography, delivering pachymetry, elevation, curvature, and dioptric power data for both corneal surfaces across a 12 mm zone. Up to 100 high-resolution sections are used to calculate biometric parameters of the anterior chamber, while fast acquisition minimizes eye-movement artifacts and ensures precise measurements. Beyond anterior-segment diagnostics, it is widely used in refractive and cataract surgery planning, with an available IOL calculation module. The system also provides objective pupil-size measurements under scotopic, mesopic, and photopic conditions.
