Fifteen years ago, vitrectomy instrumentation was quite simple. Gravity infusion and manual aspiration did not require complicated apparatus. The first vitrectomy machine’s (the VISC) cutting function was controlled by a single foot-switch (1). The microscope foot-pedal controls activated the fine focus and, in some instances, a motorized zoom magnification changing device. Although motorized automated vitreous scissors already existed, they were rarely used during vitreous surgery (2). Basically, the surgeon had two simple pedals at his disposal: one for the microscope and one for operating the vitreous cutter, hence one for each foot.
