Sirius provides many parameters to aid in the diagnosis and monitoring of the corneal surface. Combines placido disk topography with Sheimpﬂug tomography of the anterior segment and LED technology estimated life of 5000 of continuous use.
Features a continuous light volume controller for fine adjustment and illumination switches. It also captures
live photos and video recordings examinations for all patients documentations.
Videokeratoscope Software Phoenix
SIRIUS uses Phoenix software, which provides the clinician with important information about the patients cornea which prevent complications associated with ectasia before corneal surgery.
Measurement and display of sagittal and tangential
corneal curvature for anterior and posterior surfaces.
Display of the following maps: pachymetry, refractive
power (anterior, posterior and total), altimetry (anterior
and posterior) and anterior chamber depth.
Some summaries of maps for patients’ diagnosis.
Examination of the anterior segment & corneal aberrometry
Multiple maps comparison in a single display window
Display of the differences between two maps and
analysis of the differential map
Management of the patient’s medical record and tests
check-list to carryout customized statistics and research
The Phoenix software includes a section dedicated to
contact lenses, providing a printable fluo-resceinic
simulation of the contact lens on the cornea.
SIRIUS offers a unique and one of the kind technology, therefore you can utilize simultaneously two operative devices while connected with the Phoenix software. This application provides the clinician important information about the patients eyes utilizing over 9 different diagnostics.
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
For glaucoma specialists Sirius enables the
measurement of irido-corneal angles and
pachymetry. These two values are useful in
the diagnosis of the disease.
Contact Lenses Application Module
A contact lens ﬁtting module is available
which simulates the ﬁt of rigid lenses based
on an internal database of many lens
Sirius has built-in pupillography measurement
soft ware. The measurement of the pupil in
scotopic (0.04 lux), mesopic (4 lux), photopic
(50 lux) conditions and in dynamic mode.
Knowing the center and the diameter of the
pupil, is essential for many clinical procedures
which seek to optimize vision quality.
Advanced Analysis of the Tear Film
Placido disk technology allows for the
advanced analysis of the tear ﬁlm, such
as NI-BUT (Non Invasive Break-up Time).
On the basis of the pachymetry map and
corneal alti - metric data, SIRIUS allows for
intrastromal rings system planning, which
maybe an option for the correction of
refractive defects and some forms of
Meibomian glands can be viewed under
infrared light once the image is captured,
you can use the soft ware to aid in the
analysis of the condition of the glands
Offers a complete overview of the corneal
contribution to the vision. Anterior, posterior
or total corneal aberration are selectable
for several pupil diameters. The OPD/ WFE
map and the simulated vision functions
(Spot Diagram, PSF, MTF, Image convolution)
help the clinician understanding and
explaining the visual discomfort to the
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) can help the clinician in understanding or explaining the patient’s visual problems.
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.
