New Instruments for Vitreoretinal Surgery

ABSTRACT Purpose: To present the new instruments for vitreoretinal (VR) surgery. Methods: 1. to modify the conventional tacking forceps for array tacking during Argus II implantation on the right eyes, in order to perform the tacking with the right hand; 2. to modify 25-gauge ILM forceps for intraoperative optical coherence tomography (iOCT) assisted VR surgery in order to reduce the shadowing during surgery.
