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; |
