Abstract:
We developed novel multifunction vitreous forceps to decrease the frequency of forceps insertion and enable the removal of the internal limiting membrane and other intravitreal membranes for better surgical results. The basic forceps were conventional continuous curvelinear capsulorrhexis (CCC) forceps. The size of the shaft is 23G and its pointed end measures 500 microm in diameter. Additionally, there is a platform in its tip. The pointed end with platform helps to hold the membrane because the outer sheath can be moved while the tip of the forceps is fixed in position, and its pen hold type grip helps to reduce hand movement. The most advantageous thing is that the sharp point enables us to make an initial flap easily and the desired area of internal limiting membrane can be peeled off by firmly holding the platform.
