Corneal dome lens enhances visualization of ocular surface

BARCELONA, Spain — A dome-shaped lens design integrated in a novel ocular surface imaging system provides a complete view of the cornea, conjunctiva, sclera and lid margins, allowing for precise detection of abnormalities.

Ordinary slit lamp lenses can produce the bokeh effect, Vito Romano, MD, said at the European Society of Cataract and Refractive Surgeons meeting, not allowing ophthalmologists to focus on the apex and on the limbus and bulbar conjunctiva at the same time.

The new lens, which won Romano an ESCRS Pioneer Research Award, is shaped to fit the entire ocular surface from canthus to canthus, providing all-in-focus, standardized, reproducible images for accurate documentation of dry eye disease, inflammation, ocular surface lesions and infections.

The lens is integrated in the Occyo One device. The photographs produced are Digital Imaging and Communications in Medicine-compliant, allowing for seamless data transfer and integration with clinical systems.

In his presentation, Romano compared Occyo One images with traditional slit lamp photography, showing a remarkable difference in clarity, detailed view and precision.

“You can see details of the pterygium,” Romano said. “You will see all of the vascularization in a very detailed way.”

Occyo One, he said, can be an invaluable instrument for research as well as the clinic, and it has potential applications in pharmacies and optometry clinics for screening and monitoring.
