In this case, multiple surgeries were performed in the past including a traumatic cataract surgery without lens implantation in the 1950s, an anterior chamber IOL + removal, and several perforating keratoplasties due to severe herpetic infections.
With the CASIA2 it was possible to visualise the opacities in the pupillary plane. Therefore, it was possible to evaluate the extension and the area of these opacifications. Furthermore, the corneal imaging modalities permitted the evaluation of the regular and the irregular degree of astigmatism. With this information, it was much easier to decide which IOL should be used.
