Product Description
The G-4 High Mag Gonio Lens is a four-mirror, all-glass gonioscopy lens designed for enhanced magnified viewing of the anterior chamber angle. Compared with the classic G-4 Gonio, it provides 1.50x image magnification to improve visualization of the trabecular meshwork. The Posner-style handle option supports dynamic and indentation gonioscopy; the flanged version is compatible with laser trabeculoplasty. Available ring sizes and flange options allow customization for different clinical workflows.
