Description

The Volk G‑3 is a versatile three-mirror gonioscopy lens designed for detailed examination of the anterior chamber angle and retina. Its all-glass optical construction delivers clear visualization of the iridocorneal angle, retina from the equator to the ora serrata and the mid-peripheral or peripheral retina.

The three mirrors are positioned at 60°, 66° and 76°. Each mirror provides a dedicated anatomical view, while the central lens offers a clear view of the posterior pole.

The G‑3 is available in a flanged standard configuration for enhanced stability during procedures such as laser trabeculoplasty, a non-flanged standard configuration for routine gonioscopy and a compact, non-flanged mini version.
