TOMOGRAPH AND CORNEAL TOPOGRAPHER Combines placido disk topography with Sheimpflug tomography of the anterior segment. Sirius provides information on pachymetry, elevation, curvature and dioptric power of both corneal surfaces over a diameter of 12 mm. All biometric measurements of the anterior chamber are calculated using 25 sections from the cornea. Measurement speed reduces the effect of eye movement producing a high quality accurate measurement. In addition to the clinical diagnosis of the anterior segment the most common uses are: refractive and cataract surgery, an IOL calculation module is available. Objective examinations provide an accurate measurment of pupil diameter in scotopic, mesopic and photopic conditions. When combined with the corneal map they can be used for refractive surgery planning and follow up

INTRASTROMAL RINGS On the basis of the pachymetry map and corneal altimetric data, SIRIUS allows for intrastromal rings system planning, which maybe an option for the correction of refractive defects and some forms of keratoconus. FEATURES OF THE PHOENIX SOFTWARE Sirius uses the Phoenix software platform allowing patient data to be saved for future review and analysis, shared by all CSO devices. GLAUCOMA SCREENING For glaucoma specialists Sirius enables the measurement of irido-corneal angles and pachymetry. These two values are useful in the diagnosis of the disease. KERATOCONOUS SCREENING Keratoconous...

Sirius has built-in pupillography measurement soft ware. The measurement of the pupil in scotopic (0.04 lux), mesopic (4 lux), photopic (50 lux) conditions and in dynamic mode. Knowing the center and the diameter of the pupil, is essential for many clinical procedures which seek to optimize vision quality. IOL CALCULATION MODULE (OPTIONAL) This module is based on Ray-Tracing techniques, regardless of the state of the cornea (untreated or previously treated for refractive purposes), provides the calculation of the spherical and toric power of the intraocular lens.
