CSO Sirius

CSO Sirius (2014) – Advanced Corneal & Anterior Segment Analysis

Overview
The CSO Sirius, developed by Costruzione Strumenti Oftalmici
(Florence, Italy), is a high-precision, non-contact diagnostic instrument that
combines Scheimpflug tomography with Placido-disc corneal topography. This integration provides an exceptionally accurate three-dimensional
analysis of both the anterior corneal surface and
anterior segment structures.

Key Features
Dual Technology Integration: Combines a full 360° rotating Scheimpflug
camera with a 22-ring Placido-disc topographer, merging data from
the anterior and posterior corneal surfaces for
a complete clinical evaluation.
High-Precision Measurements: Accurately measures pachymetry, elevation,
curvature, and refractive power over a 12 mm diameter,
based on 25 corneal sections, minimizing movement artifacts
and maximizing reliability.

Clinical Applications & Benefits
Refractive & Cataract Surgery Planning: Provides detailed corneal maps and
supports advanced IOL calculation with optional ray-tracing modules.
Keratoconus Screening & Monitoring: Features specific indices and
elevation maps for early detection of corneal ectasia.
Glaucoma Diagnostics: Measures anterior chamber depth,
iridocorneal angle, and corneal thickness for
comprehensive glaucoma assessment.
Integrated Pupillometry: Performs measurements under scotopic, mesopic,
and photopic conditions – essential for refractive surgery planning and
visual optimization.
Dry Eye & Tear Film Analysis: Includes NIBUT (Non-Invasive Break-Up Time),
meibography, and bulbar redness evaluation for
a complete ocular surface assessment.
