HD Analyzer
The HD Analyzer noninvasively evaluates a patient’s vision by sending a low-power laser into the eye and taking a picture when the light hits the retina. The measurement of the spread of light on the retina is called the Objective Scatter Index (OSI). The HD Analyzer OSI score helps determine whether a corneal-based procedure or lens-based procedure is the most appropriate option for a patient.
About the HD Analyzer

LASIK and cornea-based candidates
Find perfect LASIK candidates by ensuring patients have clear optics and stable vision. Find early lens changes before they cause 20/unhappy LASIK outcomes. Re-direct to premium RLE procedure when necessary.

Cataract and RLE patients
The HD Analyzer is the most sensitive, objective cataract screening tool. Find cataract and refractive lens exchange patients as soon as scatter in their lens begins to affect their visual function. Ensure cataract and lens exchange surgery outcomes are great by eliminating dry eye disease as a source of visual disturbance.

Dry eye patients
Dry eye disease causes chaos in clinics because signs are not well correlated with symptoms. The HD Analyzer will objectively and non-invasively measure vision fluctuations from unstable tear film even when patients aren’t complaining of dryness or irritation. These asymptomatic patients are often missed and end up unhappy with their vision.

Patients with vision complaints (20/unhappy)

The HD Analyzer helps identify and explain vision concerns for more patients by detecting the earliest lens changes, night vision complaints, and vision fluctuations from dry eye disease.

All new patients
The HD Analyzer helps you see the quality of your patient’s vision and track changes in that quality over a lifetime of vision diseases and therapies.

Tear Film Analyzer
Designed for dry eye specialists, the Tear Film Analyzer quickly identifies dry eye disease, even if the patient has no pain or irritation symptoms. This tailored tool tests Vision Break-Up TimeTM (VBUTTM), providing an objective measurement of tear film instability and a dynamic plot of vision quality over time. It also uses external ocular photography to produce high definition images of Meibomian glands, which can be used to check for signs of dry eye disease.
