Yildirim TM, Łabuz G, Hammer M, et al. - In the present study, the researchers sought to quantify in vitro straylight induced by intraocular lens (IOL) localized opacification using an anterior segment OCT device. Using a new in-vitro application for an anterior segment OCT device, the Anterion (Heidelberg Engineering, Heidelberg, Germany), they obtained high-resolution optical coherence tomography (OCT) cross-section images of 44 explanted IOLs. Using the OCT device, different amounts of IOL opacification can be visualized. In order to visualize IOL pathologies, this high-resolution OCT imaging technique can be used. The amount of opacification was well correlated with the straylight induced by the lens. In the future, AS-OCT imaging could be used as a tool to predict the extent of visual impairment and to help clinicians quantify patients' complaints.
