Clinical procedures, such as refractive surgeries, depend on the counts of corneal cells and their nerves placed at en face corneal planes and consequently need en face corneal images with a large field-of-view [1]. However, the field-of-view of current high-resolution clinical methods, such as in vivo confocal microscopy (IVCM) and specular microscopy (SM), is optically restricted to about 0.5 mm [1,2]. Emerging in vivo research instruments derived from conventional Fourier-domain optical coherence tomography (OCT), such as ultrahigh-resolution-OCT (UHR-OCT) [3,4], Gabor-domain optical coherence microscopy (GDOCM) [5], and micro-OCT (µOCT) [6] can amplify the field-of-view up to about 1 mm; however, the cellular mosaics at that level are free of motion artifacts only in anaesthetized humans and animals, immobilized throughout the prolonged laser beam scanning in the en face plane [2].
