Phacoemulsification with vitreous loss using phacoemulsifier and vitrector concurrently: bimanual-bipedal technique.

Abstract

Vitreous loss is one of the adverse complications that can occur during phacoemulsification. Once vitreous loss is identified, procedural guidelines advise that phacoemulsification be ceased and the probe carefully withdrawn to minimize traction on the vitreous. Bimanual-bipedal technique described in this study holds the phacoemulsification probe in place and inserts the vitrectomy cutter through the pars plana port with the other hand. After removal of vitreous around the phacoemulsification tip, the vitrectomy cutter is switched to a cutting rate of zero. phacoemulsification can then be resumed with the vitrectomy cutter as a retainer of the lens fragments, similar to the hook of bimanual technique. Lens fragments are synergistically retained through aspiration between the vitrectomy cutter and phacoemulsification probe to prevent displacement. The bimanual-bipedal technique may offer a more streamlined and potentially safer approach for phacoemulsification with vitreous loss.
