Built by CSO, the Sirius is a Placido topographer and Scheimpflug tomographer for refractive, cataract, glaucoma, and contact lens practices. A 22-ring disc provides topography over 12 mm across a 1 to 100 D range at a working distance of 74 mm, while a 475 nm UV-free Scheimpflug light sections the eye. Both corneal surfaces are measured for pachymetry, elevation, curvature and dioptric power, and high-resolution corneal sections feed anterior chamber biometry.

Its defining strength is population fit. One instrument covers most of he patients a refractive or cataract practice sees; keratoconus screening and intrastromal ring planning serve the ectasia candidate. Glaucoma screening reads the iridocorneal angle with pachymetry. An optional ray-tracing module calculates spherical and toric intraocular lens power. Findings for each of these groups come from a single sitting.

Corneal aberrometry reports anterior, posterior or total contributions at different pupil diameters, with OPD, point spread and modulation transfer simulations. Contact lens fitting simulates rigid lens fits from an internal database, and videokeratoscopy under 470 nm fluorescein lighting extends to rigid and orthokeratology lenses. Pupillography records pupil centre and diameter in scotopic, mesopic and photopic light plus a dynamic mode. Tear break-up time, a dry eye report and infrared meibography complete the ocular surface set. Phoenix software shares patient data across CSO devices, with DICOM v3 compatibility under the IHE Eye Care profile. An external supply converts 100–240 V AC to 24 V DC at 40 W, and data travels over USB 3.0.

The unit measures 315 mm long, 255 mm wide, and 515 mm high. It is available to business buyers in more than 80 countries.

Refractive surgery practices, cataract clinics, glaucoma services, contact lens practices and dry eye clinics use the Sirius to examine the anterior segment. Ophthalmologists, optometrists and ophthalmic technicians operate it, and the results inform screening before corneal surgery, lens selection and ocular surface assessment.

The Sirius pairs Placido topography with Scheimpflug tomography, measuring the front and back corneal surfaces together. Pachymetry, elevation, curvature and dioptric power maps cover 12 mm, and high-resolution corneal sections feed anterior chamber biometry. A practice screening a candidate for refractive surgery reads thickness, elevation and keratoconus screening from the same examination.

Cataract work uses the optional ray-tracing module to calculate spherical and toric intraocular lens power from the measured cornea. Glaucoma services use the iridocorneal angle with pachymetry for screening. Corneal aberrometry at different pupil diameters, with OPD, point spread and modulation transfer simulations, describes how the cornea shapes the retinal image.

Contact lens practices simulate rigid lens fits from an internal database and use videokeratoscopy with 470 nm fluorescein lighting for rigid and orthokeratology lenses. Dry eye clinics combine non-invasive tear break-up time, infrared meibography and the dry eye report. Pupillography in scotopic, mesopic and photopic light adds a dynamic record.

Calibration is checked every 30 days with the supplied 8 mm radius sphere, and cleaning follows a set routine: parts away from the patient daily, and patient-contact parts after each use. Phoenix software stores each examination and shares it across CSO devices, and DICOM v3 compatibility under the IHE Eye Care profile lets results join an imaging workflow. At 7 kg, the head sits on a consulting-room table or an optional ophthalmic table.

One sitting for several patient groups

One instrument examines refractive, cataract, glaucoma, and contact lens patients. The operator changes analyses in the software.

Both corneal surfaces are measured.

Placido topography and Scheimpflug tomography are combined. Front and rear surfaces are reported together.

Thickness and elevation in one map set

Pachymetry, elevation, curvature and dioptric power are produced from the same capture. They cover 12 mm.

Screening from the same capture

Keratoconus screening and glaucoma screening use data already measured. Intrastromal ring planning draws on the same pachymetry and elevation.

Anterior chamber biometry

High-resolution corneal sections feed anterior chamber biometry. The data supports the iridocorneal angle screening.

Lens power by ray tracing

An optional module calculates spherical and toric intraocular lens power. It builds on the measured cornea.

Corneal optics described

Aberrometry reports anterior, posterior or total contributions at different pupil diameters. Simulations show OPD, point spread and modulation transfer.

Ocular surface tools included

Tear break-up time, meibography, a dry eye report and rigid lens fitting extend the examination. The patient stays at the chin rest.

Workflow-ready data

Phoenix software shares data across CSO devices, and DICOM v3 compatibility follows the IHE Eye Care profile. Results can join an existing imaging workflow.

22-ring Placido disc

A 22-ring disc is reflected from the front of the cornea. That reflection is the basis of the topography.

Scheimpflug tomography

A 475 nm UV-free Scheimpflug light sections the eye. It measures both corneal surfaces from these sections.

Coverage and range

Topographic coverage is 12 mm. The dioptric range is 1 to 100 D.

Working distance

The working distance is 74 mm. A chin rest and chin cup position the patient.

Corneal maps

Pachymetry, elevation, curvature and dioptric power are mapped for both corneal surfaces. Maps cover 12 mm.

Anterior chamber biometry

High-resolution corneal sections feed the anterior chamber biometry. The result supports glaucoma screening.

Keratoconus screening

Screening software flags ectasia risk from the measured surfaces. It sits alongside intrastromal ring planning.

Glaucoma screening

The iridocorneal angle is read together with pachymetry. The screening runs from the same sitting.

Corneal aberrometry

Anterior, posterior or total corneal aberrations are reported at different pupil diameters. Simulations include OPD, point spread and modulation transfer.

Ray-tracing lens calculation

An optional module calculates spherical and toric intraocular lens power. Licensing is set through Phoenix software.

Contact lens module

Rigid lens fits are simulated from an internal database. Videokeratoscopy under 470 nm fluorescein lighting extends to rigid and orthokeratology lenses.

Tear film and glands.

Includes non-invasive tear break-up time, a dry eye report, and infrared meibography. The glands are imaged without contact.

Pupillography

Pupil centre and diameter are recorded in scotopic, mesopic and photopic light, with a dynamic mode. An infrared LED illuminates the pupil.

Chin rest and base travel

The chin rest moves 70 mm ± 1 mm, and the chin cup stands at least 24 cm above the table. The base shifts 105 × 110 × 30 mm in X, Y and Z.

Phoenix and DICOM

Phoenix software stores and shares patient data across CSO devices. DICOM v3 compatibility follows the IHE Eye Care profile.

Data transfers over USB 3.0. An external supply accepts 100–240 V AC at 50/60 Hz and delivers 24 V DC at 40 W.

Computer requirements

CSO specifies an Intel i5 quad-core at 2.5 GHz, 8 GB of RAM, 1 GB of dedicated graphics memory, a 1920 × 1080 display and Windows 11 (64-bit).

The Sirius suits refractive, cataract, glaucoma, and contact lens practices that want the front and back corneal surfaces and the anterior chamber in one sitting. Its deciding strength is population fit: keratoconus screening, glaucoma angle screening, aberrometry and rigid lens fitting all run from a single examination, and an optional ray-tracing module adds intraocular lens power for cataract work. Phoenix software keeps each record in one place and shares it across CSO devices, while DICOM v3 compatibility under the IHE Eye Care profile lets results join an existing imaging workflow. Calibration is checked every 30 days with the supplied 8 mm radius sphere. The Sirius is CE-marked as a Class IIa medical device.
