SIRIUS
TOMOGRAPH AND CORNEAL TOPOGRAPHER
Combines placido disk topography with Sheimpflug tomography of the anterior segment. Sirius provides 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 25 sections from the cornea. Measurement speed reduces the effect of eye movement producing a high quality accurate measurement.
In additi on to the clinical diagnosis of the anterior segment the most common uses are: refractive and cataract surgery, an IOL calculati on module is available. Objective examinations provide an accurate measurement of pupil diameter in scotopic, mesopic and photopic conditions. when combined with the corneal map they can be used for refractive surgery planning and follow-up.
KERATOCONOUS SCREENING
Keratoconous screening provides the clinician with important information about the patinets cornea. Understanding this can help prevent complications associated with ectasia before corneal surgery is undertaken.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.PUPILLOGRAPHY
Sirius has built-in pupillography measurement software. 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.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.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). Based on the Ocular Surface Disease Index questionnaire (OSDI), limbal and conjunctival hyperaemia, Meibomian glands analysis, tear meniscus analysis and tear osmolarity, calculated merging together all partial scores, provides an owerall evaluation of the clinical condition of the patient for a comprehesive diagnosis of the dry eye disease.Author information: Pediatric Ophthalmology Unit, A.
