A recently developed instrument (vitrophage) has been proven effective in removal and replacement of vitreous and in the cutting of vitreous strands in experimental vitreous hemorrhage. The instrument is inserted at the pars plana under direct observation of the fundus through a three-mirror lens and operating microscope, and it can be manipulated easily inside the eye by a specially-designed manipulator. The technique and preliminary results of this experimental study are reported.
