Intraoperative spectral domain optical coherence tomography (SD-OCT) image of a donor cornea for penetrating keratoplasty observed through a viewing chamber. a Representative microscope image (surgeon’s view) observed from the anterior (left). Normal corneal curvature and stromal texture with high reflectivity of epithelium and endothelium cell layers were observed by intraoperative OCT (right). b Microscopic image observed from the posterior cornea (left) and intraoperative OCT image (right)
