HD Analyzer


Fast and comprehensive for front-end decision making.

20/20 visual acuity does not guarantee vision quality. Only the HD Analyzer Optical Quality Analysis System (OQAS) measures total optical quality, accounting for light scatter caused by pathologies like early cataracts and tear film instability. Wavefront aberrometers overestimate patient optical quality because they assume clear optics—ignoring scatter.

The HD Analyzer OQAS measures the Objective Scatter Index (OSI) of each patient, offering the only complete and objective measurement of vision quality available today. Measuring scatter from early lens changes and asymptomatic dry eye disease is the key to great premium outcomes and happy patients.

Differences in the Objective Scatter Index (OSI) for a patient can result in 20/20 vision that remains blurry. Even a flawlessly performed surgery can result in a 20/unhappy outcome if you don’t screen for scatter from the lens and tear film ahead of time. The HD Analyzer Optical Quality Analysis System is the only diagnostic tool that can pre-diagnose the subtle, forward light scatter that affects surgical outcomes for cataract and refractive patients.

1) Check For Early Cataracts

Identify the right candidates for the right procedures.

Optics clear for cornea-based procedures.

HD Analyzer Low OSI

High OSI
Likely a good candidate for lens-based procedures.

HD Analyzer High OSI


2) Check For Dry Eye Disease

Use dynamic screening capabilities to diagnose vision fluctuations and structural damage.

Vision Break-Up Time is >10 seconds
Stable tear film will not affect premium outcomes.

HD Analyzer Vision Break-Up Time

Vision Break-Up Time is 5.5 seconds
Vision is impacted by unstable tear film—good candidate for dry eye therapy.
