1. IntroductionEctasia after penetrating keratoplasty (PK) is a late complication that can occur after the procedure, characterized by the thinning and steepening of the cornea at the donor–recipient junction [1] (Figure 1), potentially leading to high irregular astigmatism and significant visual impairment. It can occur years or decades after PK is performed for any indication, but it is relatively rare in non-keratoconus eyes [2,3,4,5].

1. Intraoperative OCT: Technology and CharacteristicsAnterior segment OCT (AS-OCT) was described for the first time in 1994 by Izatt et al. as an essential tool for the clinical diagnosis and follow up of many corneal pathologies [1]. Thanks to its high level of resolution, AS-OCT provides a near-histologic cross-sectional and tomographic image of the tissues, allowing for the detailed evaluation of clinical conditions, and is able to impact medical and surgical decisions.
