Visiometrics launches HD Analyzer optical quality analysis system
This device measures light scatter, which is not measurable using traditional wavefront aberrometry.
Barcelona, Spain-Visiometrics has launched the next generation of its Optical Quality Analysis System (OQAS), the HD Analyzer, following the issuance of the European CE mark for the system.
Employing double-pass retinal imaging, the diagnostic system provides a measure of light scatter (OSI), which can lead to degradation in image quality. Light scatter is not measurable using traditional wavefront aberrometry and presents a diagnostic challenge that only the HD Analyzer is currently able to answer.
The HD Analyzer can be used for:
Diagnosing and monitoring the evolution of pathologies or refractive disorders.
Evaluation of the OSI level for the early detection of cataract and the determination of its degree of maturity.
Comparing pre and post cataract and refractive surgery measurements.
Precise Modulation Transfer Function measurement, which is overestimated by aberrometers when scattering exists, as in cataract patients.
Evaluating tear film quality.
Objective measurement of the amplitude of accommodation and pseudoaccommodation.
