Resumen:
The advance in the knowledge of corneal ultrastructure that previously would have been considered a curiosity or just intellectual data, today is essential for the clinician. The purpose of this review is to address the elements that, based on the authors' criteria, are more relevant to the "new" anatomical (histological) aspects of the cornea and how they affect the relatively new surgical techniques, emphasizing the role of "Dua's layer." The composition of the corneal stroma also varies according to depth. Corneal tissue obtainment varies according to the dissection technique used, although it is true that in pneumodissection pre-descemet stromal remnants remain, but they do not constitute a new anatomical layer. The differences in hydration and disposition between the corneal lamellae cause the cornea to behave differently depending on the dissection plane. Age-related changes facilitate the procurement of the descemet-endothelium membrane, as it becomes thicker and easier to manipulate. © 2019 Publicaciones Permanyer. All rights reserved.
