DescriptionThe 4 mirror mini Gonio lens provides a complete view of the chamber angle, with the convenience of a small sized body. This enables easier manipulation within a small orbit.

Features:

  • Small body and ring for ease of use within the orbit
  • 4 mirrors

For those who prefer the versatility that a second mirror adds, then you may want to consider the Volk g-2 trabeculum. It features the same 1.5x magnification as the G-1 but offers two opposing mirrors angled at 60° and 64° respectively.
