CE Mark And Launch Of Visiometrics HD Analyzer, Optical Quality Analysis System

Visiometrics has gained CE mark approval for the next generation of its Optical Quality Analysis System, the HD Analyzer. Launch in Europe follows through Medeuronet, the company’s exclusive distributor.


The HD Analyzer is a unique diagnostic system that allows for an objective analysis of optical quality. The system provides a measure of light scatter, which is caused by a variation of the refractive index, corneal disease or imperfections on the ocular surface, 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 uses what is called “double-pass retinal imaging” to analyze a punctual light source on the retina. The size and shape of the light determine the higher order aberrations and scattered light. The system provides users with the Point Spread Function (PSF), Objective Scattering Index (OSI), as well as the Modulation Transfer Function (MTF).

The versatile HD Analyzer can be used for:

· Diagnosing and monitoring the evolution over time of pathologies or refractive disorders.

· Evaluation of the level of light scatter (OSI) for the early detection of cataract and the determination of its degree of maturity.

· Comparing pre and post cataract and refractive surgery measurements.

· Precise measurement of MTF (Modulation Transfer Function), which is overestimated by aberrometers when scattering exists, as in cataract patients.

· Evaluation of tear film quality

· Objective measurement of the amplitude of accommodation and pseudoaccommodation.

 Company comments

“We are pleased to have achieved this milestone and are excited to bring this technology to Europe. The HD Analyzer has been well received by US ophthalmologists and we anticipate a similar reaction from European ophthalmologists,” said Jan Bonel, Visiometrics CEO. “The HD Analyzer gives ophthalmologists the ability to go beyond traditional means of vision assessment, which is increasingly important in today’s ophthalmology practice.” he said.
