Combines placido disk topography with Sheimpflug tomography
of the anterior segment. Sirius provides informati
on on pachymetry, elevati on, 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 secti ons from the cornea.
Measurement speed reduces the eff ect 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: refracti ve and cataract
surgery, an IOL calculati on module is available.
Objecti ve examinati ons provide an accurate mea- surement
of pupil diameter in scotopic, mesopic and photopic
conditi ons. when combined with the corneal map
they can be used for refracti ve surgery planning and follow-up.
