Osiris-T Pyramid Wavefront Sensor - (CSO, Italy)
The Osiris-T aberrometer is a CE-certified device that operates via a high-resolution four-faced pyramid wavefront sensor (PWS) to analyze light intensity among four images (sub-apertures) of the patients ́entrance pupil akin to a Foucault knife-edge test. Thereby measurements of the wavefront and refractive error can be quantified non-invasively. The sampling density of the wavefront error is 45,000 points at maximum pupil. The device uses a near-infrared extended light-emitting diode source emitting at 850 nm. Its is additionally intertwined with a corneal topography system to also characterize the corneal aberrations and compute via direct subtraction the internal ocular optics.
