When flow and stability work together

Fast vitreous removal

Fast vitreous removal: The significantly increased aspiration flow of 61 % in 23G speeds up vitreous removal^*³.

Continuous aspiration

Continuous aspiration: The permanently open port provides continuous aspiration and results in reduced traction on the retina compared with cutters with a conventional guillotine mechanism^*.

High cut rates

High cut rates: With up to 15,000 cpm on OS 4 Up the Continuous Flow Cutter delivers powerful performance in the OR^*.

Cutting near the tissue

Cutting near the tissue: Thanks to a minimal distance of 0.18 mm in 27G between the port opening and the surface, the Continuous Flow Cutter allows work close to the tissue^*.

With its 0.1 mm narrow, double-edged blade, the Continuous Flow Cutter cuts both forwards and backwards, effectively doubling the removal of vitreous portions per cycle up to 15,000 cpm^*.

Continuous aspiration

Higher aspiration for more efficiency

The higher the flow, the more efficient the procedure. Compared with the previous generation, the new Continuous Flow Cutter delivers 61 % more aspiration flow in 23G, enabling efficient vitreous removal during vitrectomy^*.

Cannula stability

Greater stability through increased stiffness

The thinner the gauge, the more stability matters. In 27G, the Continuous Flow Cutter delivers 81 % increased stiffness for improved stability^*.

FAQ

In a nutshell about
vitreous removal

Increased aspiration supports fast and efficient vitreous removal. In the Continuous Flow Cutter, aspiration is increased by 61 % in 23G, 40 % in 25G, and 5 % in 27G compared to the previous generation ^*.

Cutter stiffness matters because it supports cannula stability during vitrectomy and helps prevent the cannula form bending. In the Continuous Flow Cutter, stiffness is increased by 8 % in 23G, 47 % in 25G, and 81 % in 27G compared to the previous generation^*.

Work close to the retinal tissue is supported by a minimal port-to-surface distance. The Continuous Flow Cutter has a distance of 0.18 mm in 27G between the port opening and the surface, enabling cutting close to the tissue ^*.
