The Volk G-1 Trabeculum ophthalmic gonioscopic lens is designed for detailed examination of the anterior chamber angle and trabecular meshwork, providing high image magnification and accurate assessment of structures during clinical diagnosis and treatment.
- A single mirror optical system (62°) allows precise visualisation of the front camera angle and trabecular meshwork.
- The ~1.50× image magnification ensures extremely detailed visibility of structures and high diagnostic accuracy.
- The ~0.67× laser spot size factor allows precise control of the laser effect during treatments.
- The all-glass optical construction ensures high image clarity, contrast and durability.
- Available in versions with a support ring (~15 mm contact diameter) and without a support ring (~8.4 mm) to suit different clinical scenarios.
- Rotation of the lens is required to assess all quadrants of the front camera angle.
- Suitable for laser trabeculoplasty (ALT) and detailed diagnostics; not recommended for selective laser trabeculoplasty (SLT).
- The compact optical system allows precise image focusing and high-precision interventions.
