MANI MVR19 Ophthalmic Knife - 19 Gauge (1.5mm) MVR-Lance, Straight Micro-Vitreoretinal Blade (Box of 6)

MANI MVR-Lance Knife | 19G / 1.5 mm | MVR19

The MANI MVR19 represents the 2026 pinnacle of ophthalmic microsurgical cutting technology. Utilizing MANI’s proprietary Hard Fiber Stainless Steel, these 19-gauge lance knives are engineered for the high-precision entry required in vitreoretinal and advanced cataract procedures.

The MVR19 is distinguished by its Crosslapped Edge—a specialized polishing technique performed vertical to the cutting edge—which achieves a level of "Ultimate Sharpness" that reduces tissue drag and ensures a self-sealing, standardized incision. This is critical for maintaining intraocular pressure (IOP) stability and preventing post-operative leakage.

Key Performance Features

• Hard Fiber Stainless Steel: MANI’s original austenite steel provides superior tensile strength and ductility. This allows for a thinner blade profile that is more resistant to tip deformation or breakage compared to standard stainless steel.

• 1.5 mm Blade Width: Specifically calibrated for 19-gauge access, providing the precise clearance needed for specialized vitreoretinal instrumentation, infusion cannulas, or secondary incisions.

• Crosslapped Sharpness: The vertical polishing process eliminates microscopic burrs, ensuring the knife glides through the sclera or cornea with minimal resistance, thereby reducing the risk of unintended tissue "tugging."

• Non-Glare Surface Treatment: The blade body features a specialized finish that diffused microscope light, preventing distracting reflections while maintaining high-contrast visibility of the sharp edge.

• Stabilized Trajectory: The patented bevel geometry is designed to prevent "wavering" during entry, providing the surgeon with absolute control over the incision’s path and length.

Clinical & Institutional Advantages

• Superior Wound Integrity: The sharpness of the MANI edge produces a "cleaner" cut with less cellular trauma, which directly contributes to faster healing and more reliable self-sealing incisions.

• Consistency Across Procedures: As a single-use instrument, the MVR19 provides the same factory-perfect sharpness for every case, eliminating the variability and safety risks associated with re-sharpened reusable blades.

• Strategic Procurement: Sourcing genuine MANI overstock allows ophthalmic facilities to provide Japanese-engineered precision at a significant savings over standard contract pricing.

Ideal Applications

• Vitreoretinal Surgery: Creating sclerotomy sites for 19-gauge instrumentation and infusion.
