Corneal biomechanical properties can provide important information to measure tissue health. Elastography provides a useful tool to measure the biomechanical properties of tissues in vivo, but typically relies on measuring a response to external excitation. Passive elastography is a method to assess mechanical response to physiological pressures, which can be useful in the field of ophthalmology. In this work, we utilize our technique, Hb-OCE, to measure the mechanical properties of cornea in vivo. Furthermore, we were able to successfully distinguish stiffness in an untreated and crosslinked cornea using this technique, demonstrating its effectiveness as a tool for measuring corneal biomechanics.
