Corneal topographer SIRIUS+

tabletop

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 measurment of pupil diameter in scotopic, mesopic and photopic conditions. 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, 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. 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.
