Background: During valve free 23G vitrectomy frequently manipulation of the trocars with forceps is required.

Methods: A new forceps that has been specially customized for one step valve free 23G vitrectomy will be presented. The teeth of this forceps are ideal for external and internal stabilisation of 23 trocars.

Advantages: This new forceps allows atraumatic manipulation of the conjunctiva and stabilisation of the globe during insertion of the first trocar. During introduction of the second and the third trocar the forceps is ideally customized for rotation and fixation of the globe through insertion of the forceps into trocars that previously have been placed. Thus, the safety of trocar insertion and of introduction of the infusion cannula can be increased. Dislocated trocars can be re-positioned more safely. During fluid-air or air-gas exchange the globe can be pressurized more easily and more dynamically according to the surgeon’s needs and preferences (“dynamic valve”). Furthermore, reflux during trocar removal may be prevented by introduction of the specially designed forceps teeth into the trocar openings.
