The BD Atomic Edge™ Blade Technology

Developed through the technology and processes used in the fabrication of semiconductors, the BD Atomic Edge™ silicon disposable blades deliver higher quality and performance than disposable metal blades. It is the first disposable silicon blade for ophthalmic surgery.

The BD Atomic Edge™ represents a breakthrough in blade technology that uses silicon with its single crystalline molecular structure to deliver edge sharpness and performance approaching that of a diamond blade. The BD Atomic Edge™ blade features an edge radius of 40 nm, comparing to approx. 600 nm for metal knives, and close to 20 nm for diamond knives.

BD Atomic Edge™ Safety Knives

The BD Atomic Edge™ safety knives are designed to combine diamond-like performance with single-use safety and convenience.

The BD Atomic Edge™ blade architecture is designed for incision control. The double-bevel design ensures straight penetration in single or two-plane clear cornea incision. The blade has non-sharpened parallel sides that minimize the risks of accidental side-cutting. The tip angle has been designed to produce the correct penetration depth, resisting over penetration.

Similar to BD Beaver™ Safety Ophthalmic Knives, BD Atomic Edge™ knives feature an advanced retractable protective shield designed to protect healthcare professionals and to protect the blade. The shield’s slider mechanism is designed to open and close with a single-hand operation. 

The first available products with BD Atomic Edge™ technology are slit knives, in 2.8mm and 3.0mm.
