Anterior Segment‐OCT (AS‐OCT) is a non contact high Resolution Imaging system. It uses 1310 nm Coherent light and can scan up to 6 mm in Depth and thanks to a maximum scan width of 16 mm it can provide limbus to limbus cross sectional images even thru an opaque cornea. The acquisition is fast up to 8 Frames per second (almost video like). We decided to compare it to the Ultrasound Biomicroscopy (UBM), that is considered to be the gold standard of AS imaging. In a randomized comparative case series in patients with pseudophakic bullous keratopathy (PBK), we studied with AS‐OCT and UBM the anatomical modifications after a triple procedure involving: formerly implanted AC IOL removal followed by the fixation of a Verisyse Aphakic IOL either over or under the Iris. The AS anatomy was best respected in patients who had the Verisyze IOL implanted behind the iris. Measurements obtained with AS‐OCT and UBM were well correlated. AS‐OCT is a reliable and easy to use option for accurate AS imaging before and after surgery in patients with PBK.
