Scientists at the International Centre for Translational Eye Research have created a prototype imaging system capable of tracking corneal stiffness at nine distinct locations at the same time. The noncontact technology could transform how clinicians assess corneal biomechanics, offering earlier and more precise detection of disorders like keratoconus. The innovation addresses a critical gap in current diagnostic tools, which often rely on single point measurements or invasive methods.
The cornea, the eye's transparent outer layer, plays a vital role in vision by focusing light onto the retina. Its mechanical properties, such as stiffness and elasticity, are key indicators of eye health. Disorders like keratoconus, where the cornea thins and bulges outward, can severely impair vision if not detected early. Current diagnostic methods often measure corneal biomechanics at a single point or require contact with the eye, limiting accuracy and patient comfort.
The new imaging system, developed by researchers at ICTER, overcomes these limitations by using advanced optical techniques to assess corneal mechanics at nine locations simultaneously. The prototype employs a combination of air puff stimulation and high speed imaging to capture real time responses without touching the eye. This noncontact approach reduces discomfort and infection risks while providing a more comprehensive picture of corneal health.
