Bimanual Vitrectomy with 4-Port Trocar System

  • Ulrich Spandau

Bimanual vitrectomy is an essential part of modern Minimal Incision Vitreoretinal Surgery (MIVS). By inserting a stationary chandelier light in the sclera (4-port vitrectomy, Fig. 6.1), the surgeon has two active hands. To operate with two active hands is a new and exciting method of surgery. For example, in retinal detachment surgery, one can indent the sclera with one hand and vitrectomize the vitreous base with the other hand. In diabetic retinopathy, one can apply laser photocoagulation up to the ora serrata with the help of a scleral depressor. One can remove membranes with two different instruments and also apply counteraction.
