**9. Future directions**

Future developments include clinical application of the technique to screen donor corneas before transplantation. The newest generation of imaging, micro-OCT (μOCT), uses an isotropic spatial resolution of 1–2 μm. It can detect key cellular and subcellular components such as keratocytes, collagen fibers and corneal nerves. This new technology has the potential to improve our understanding of corneal anatomy and disease.
