Purpose of ReviewAnterior segment optical coherence tomography (AS-OCT) is a new system to obtain high-resolution cross-sectional images of the cornea and anterior chamber. In eyes with corneal opacity, it is often difficult to observe and assess intraocular structures using slit-lamp microscopy. Because AS-OCT uses longer-wavelength infrared light, it enables deeper penetration with less reflection even in eyes with severe corneal opacity. Thus, AS-OCT is useful for imaging the cornea and anterior segment structures before and after corneal transplantation.
