The standard fluid design (flanged glass contact element) provides a stable platform during laser treatment of anterior segment.
The NF (no fluid) design features a small 8.4mm radius contact surfaces that's ideal for both static and dynamic gonioscopy while eliminating the need for viscous interface solutions such as methylcellulose. Four NF models are available, including: small hand held (25.5mm diameter), large hand held (29mm diameter), 2-in1 handle. All 3 NF models share the same high quality imaging element. Choose the model that you are most comfortable using.
Each reflecting surface incorporates a high efficiency vacuum deposited mirror coating, double over coated with silicone dioxide and catalyzed polyurethane polymer to provide the ultimate in protection.
Volk recommends the use of the goniolaser "Flanged" model for laser treatment.
