The two A.V.I. Lenses have high resolution aspheric optics so that sharp images are obtained even in the periphery of the lens. They are smaller in size than the Volk Transequator or Quadraspheric lenses. Since stereoopsis is important in vitreous surgery, the lenses have been designed to enable membrane dissection.
- 68 degree or equatorial lens provides visualization to the equator at higher magnification for epiretinal dissection and visualization of the macula region;
- 130 degree or peripheral lens is preferred for vitreous base surgery, fluid air exchange and endophotocoalgulation;
- Available with a lens retaining ring and a set of fixed angle lens handles for the 68 and 130 degree or with one universal handle;
