CorneaGen Partners With Visiometrics to Offer HD Analyzer, Tear Film Analyzer
CorneaGen will become the US distributor of the HD Analyzer and Tear Film Analyzer from Visiometrics. These diagnostic tools will join Intacscorneal implants and the Kamra Inlay in CorneaGen’s new refractive cornea division. The Tear Film Analyzer quickly identifies dry eye disease, while the HD Analyzer sets up ideal surgical outcomes for cataract and refractive procedures by comprehensively evaluating how crisp, clear and stable a patient’s vision is prior to treatment.
“The HD Analyzer has become the preferred vision screening tool for refractive lens exchange (RLE), but is truly valuable in assessing all new patients,” said CorneaGen President and CEO Monty Montoya. “We are looking forward to sharing this technology with surgeons because it allows them to evaluate and educate patients efficiently, then confidently deliver the outcomes their patients desire.”
The HD Analyzer noninvasively evaluates a patient’s vision by sending a low-power laser into the eye and taking a picture of the light as it 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.
With the HD Analyzer, surgeons also can quickly identify patients whose lens changes are likely to produce a 20/unhappy LASIK outcome, then use the test report to help them understand the need to invest in RLE or another premium procedure. The simple report allows patients to clearly see the evidence of light scatter, which can be difficult to explain.
“Light scatter really matters—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,” said Jérome Marzinski, CEO of Visiometrics. “Only the HD Analyzer measures total optical quality and can pre-diagnose the subtle, forward light scatter that affects surgical outcomes for refractive and cataract patients.”
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 time, 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.
The HD Analyzer also provides vision break-up time and meibomian gland imaging in addition to testing depth of focus, light condition, and Purkinje versus pupil center location.
