Abstract

The focusing power of the human eye is provided by the cornea and the crystalline lens (CL). The latter provides the capacity to alter its shape and provide fine focus adjustment during the accommodation process. We extended standard structural OCT analysis to precisely follow dynamically subtle OCT signal phase changes within the human CL during accommodation. Imaging was performed using the SS-OCT system equipped with the Badal system to provide accommodation demand. The presented phase-sensitive analysis allows for distinct motion extraction such as lens wobbling, bulging, or any other deformation that can be significant for crystalline lens accommodation-associated biomechanics.
