easyVit control for Pars Plana Vitrectomy
easyVit is a new pedal control mode for vitreoretinal surgery. It combines aspiration and cut rate in a single linear pedal movement, so planned PPV phases can be performed without changing programs.
Dual-linear pedal control
The pedal moves both vertically and horizontally, allowing the surgeon to control two different functions simultaneously and independently.
Linear pedal control
A single linear pedal movement provides direct control of the assigned function. The further the pedal is depressed, the higher the output.

Why the pedal makes the difference

«What I like most is the footswitch: not only is the laser integrated, it also allows me to change the light settings with my pedal to enhance visibility and play with the contrast. My absolute favourite feature of the pedal is the luxury of being able to switch between fluid and air (and back, and back again...) with my foot.» ^D1
