2014 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.
