🧠 This study investigates how corneal biomechanical properties, particularly extrafibrillar matrix stiffness and collagen fiber nonlinearity, affect the accuracy of intraocular pressure (IOP) estimation. Using finite element simulations (FEM) and optical coherence elastography (OCE) experiments, the team demonstrated that these properties can introduce errors of up to 5 mmHg in IOP measurements, highlighting the need for more biomechanically informed estimation models.

We proudly celebrate this contribution, which enhances the international visibility of the research developed at GIBIO and reaffirms our commitment to interdisciplinary, collaborative, and cutting-edge science.
