The occurrence of a dense cataract is most often identified in the slit lamp examination, where the view to the fundus may be impeded.
Detecting macular pathologies that could affect surgery and outcomes is especially important. Posterior OCT has become the gold standard here and supports informed decision-making on IOL selection for the patient. 3,4
Furthermore, accurate axial length measurement is critical for the IOL power calculation, a key step to achieving the targeted refraction.2 But as dense cataracts are difficult to penetrate precise measurement can be challenging for optical biometers.
Anterior swept source OCT devices can overcome this issue. In a recent study, ss-OCT technology was shown to significantly increase the proportion of successful axis eye length measurements compared to PCI technology.5
