Purpose Optical coherence tomography (OCT) after extended use in diagnosis of retinal diseases has now become a new cross‐sectional imaging approach useful for anterior segment (AS) imaging. The potential advantages and limits using AS‐OCT in the field of corneal grafting are presented. Methods Systematic literature review search and clinical examples focused in the fields of corneal grafting procedures by using two different OCT systems (time domain and spectral domain). Results AS‐OCT technology, using 1310 nm wavelength, offers some advantages as compared to high frequency ultrasound system, the main being the absence of contact with the eye. It provides relatively accurate morphology and measurements of different structures of the AS and of the cornea. Morphometry of corneal structures is particularly useful in the preoperative evaluation lamellar keratoplasty procedures, including anterior lamellar keratoplasty, deep anterior lamellar keratoplasty and endothelial keratoplasty. Morphology of the transplant, accurate measurements of lamellar graft, interface profile evaluation and complication assessment, including posterior lamellar disc detachment are feasible. Conclusion AS‐OCT presents advantages in the clinical practice in the field of corneal disease and surgery. This technology alone should not substitute a comprehensive clinical examination but may offer valuable insights in the quantification and observation of fine details which can be obscured or not detectable during conventional slit‐lamp examination.
