SIRIUS plus – Placido-Scheimpflugcamera

Placido-Scheimpflugcamera Sirius+ with exceptionally fast and easy image acquisition

The clever combination of the Placido topography with the Scheimpflug tomography offers highly precise measurements.

Highest precision for front and rear surface

Sirius+ combines placido disk topography with Scheimpflug tomography of the anterior segment providing 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 up to 100 HR corneal sections.
Measurement speed reduces the effect of eye movement producing a high quality accurate measurement.
In addition to the clinical diagnosis of the anterior segment the most common uses are refractive and cataract surgery, an IOL calculation module is available.
Objective examinations provide an accurate measurement of pupil diameter in scotopic, mesopic and photopic conditions.

The Phoenix Software

The Sirius+ uses the cross-device Phoenix software, which allows you to perform extensive analyses, evaluations and progress reports.
Patient data and measurement results are stored in a modern database and can be shared between many devices, such as the digital slit lamp “DigiPro”.

Corneal Aberrometry

Aberrometric analysis offers a complete overview of the corneal aberrations. It is possible to select the contribution of the anterior, posterior or total cornea for different pupil diameters. The OPD/WFE maps and the visual simulations (PSF, MTF, image convolution with optotype) can help the clinician in understanding or explaining the patient’s visual problems.

Glaucoma-Screening

For glaucoma specialists Sirius+ enables the measurement of irido-corneal angles and pachymetry. These two values are useful in the diagnosis of the disease.

Keratoconus Screening

Keratoconous screening provides the clinician with important information about the patients cornea. Understanding this can help prevent complications associated with ectasia before corneal surgery is undertaken.

Pupillography

Sirius+ has built-in pupillography measurement software. The measurement of the pupil in scotopic, mesopic, photopic conditions and in dynamic mode. Knowledge of the center and the diameter of the pupil, is essential for many clinical procedures which seek to optimize vision quality.

Intrastromal Rings

On the basis of the pachymetry map and corneal altimetric data, Sirius+ allows for intrastromal rings system planning, which may be an option for the correction of refractive defects and some forms of keratoconus.

IOL Calculation Module (optional)

This module is based on Ray-Tracing techniques, regardless of the state of the  cornea (untreated or previously treated for refractive purposes), provides the calculation of the spherical and toric power of the intraocular lens.

Videokeratoskopy

The use of a new white light and blue light illumination source, for the stimulation of Fluorescein, will extend the functions of the device for the application rigid and ortho-k contact lenses.

Contact Lens Application Module

A contact lens fitting module is available which simulates the fit of rigid lenses based on an  internal database of many lenses and manufacturers.

Advanced Analysis of the Tear Film

Placido disk technology allows for the advanced analysis of the tear film, such as NIBUT (Non Invasive Break-up Time).

Meibography

Meibomian glands can be viewed under infrared light. Once the image is captured, you  can use the software to aid in the analysis of the condition of the glands.

Comprehensive Dry Eye Report

The colour camera allows the measure of tear film Break-up time, Meibomian glands analysis, Conjunctival and limbal hyperemia and tear meniscus height. The Dry Eye report provides a comprehensive assessment of the patients corneal condition and helps in the diagnosis of Dry Eye Disease (DED).
