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 additi on to the clinical diagnosis of the anterior segment
the most common uses are: refractive and cataract
surgery, an IOL calculati on module is available.
Objective examinations provide an accurate measurement
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.
