Used to perform the main incision/tunnel (for the introduction of a phaco needle). Symmetric sharp edges of the blade ensure even diving inside the tissue with less corneal distortion. Profile of the incision is directed to the anterior chamber. Titanium handle with locking mechanism. Extreme sharpness of the blades. Minimal pressure. Up to 3000 incisions. Natural diamond. Predictable cuts and architecture of the wound for more consistent healing. Potentially reduced risk of wound leak. The cutting edge of 4-10 nm pushes the molecules apart without damaging them and allows the penetration with minimal pressure.
