Purpose: Beside its property to almost evenly illuminate the fundus the multiport illumination system advantageously allows to operate bimanually on the vitreous and retina. Nevertheless, when used in the usual manner angled instruments or those with a diameter greater than 0.99 mm (19 gauge) cannot be used with this device.
Method: In a video presentation the differences in principle are shown between a usual pars plana vitrectomy, one that employs the multiport illu-mination system and the modified use of this device with concern for ar-rangement of mini-infusion, illumination devices as well as feasibility for further instruments. Scenes from the operating theatre showing the treat-ment of various diseases will demonstrate the modified use of the multiport illumination system and its expanded possibilities to be used with large-calibre and angled instruments.
Results: The modification of the multiport illumination system brings together possibilities of bimanual surgery of the posterior segment and the wide selection of tools to be used with conventional pars plana vitrectomy. In addition it will enable the surgeon to bring in innovative instruments such like diamond knives for posterior segment surgery.
Conclusions: The modification of the multiport illumination system extends the arsenal of the vitreoretinal surgeon, is able to have surgical manoeu-vres performed more safely and thus possibly makes the management of difficult situations at the posterior segment easier.
