“Le System”: A Unified Microsurgical Center
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.
