Examinations in the blink of an eye WASCA Analyzer -Precision in Focus When your patients entrust you with their eyesight, their vision and your expertise converge. For the world’s most advanced surgical and diagnostic solutions in ophthalmology, you can turn to Carl Zeiss Meditec. We’re committed to earning your trust anew, every day. 13 milliseconds Eye registration is all it takes delivers new insights The heart of the WASCA Analyzer is a high-resolution The WASCA Analyzer captures multiple structural Shack-Hartman wavefront sensor. With a sensor resolu- reference points on the eye for precise and repeatable tion of 210 µm and 1452 measuring points, it measures registration. In addition to capturing high-resolution wavefront aberrations with unparalleled detail and scleral blood vessel and iris structure images, the precision. WASCA Analyzer measures the position of the limbus Technical data The extremely short measuring time of 13 millise- margin and pupil center. This combination provides a conds virtually eliminates inaccuracies caused by eye unique reference for the wavefront aberrations on the movements during measurement. High accuracy and eye for confident, repeatable treatment placement and Sensor type robustness throughout the instrument's large measure- combination of data. Measuring range WASCA Analyzer ment range is provided by a unique optical design that Shack-Hartmann -15 D to + 7 D including 5 D cylinder No. of measuring points eliminates sensor lenslet spot overlap. This allows the 1,452 total 800 in a 7 mm pupil cannot be measured on many other wavefront devices. Beam splitter SLD beam Sensor Cornea Lens Retina Higher-order aberrations are a complex, inhomogeneous distribution of refractive power within the pupil that cannot be described by refraction data such as sphere and cylinder. Optical aberrations such as coma and spherical aberration are not detected by conventional refraction and often manifest themselves in subjective complaints such as poor night vision.
