Graefe-Arruga Cataract Knife

Description

Graefe-Arruga Cataract Knife

The Graefe-Arruga cataract knife joins the classic Graefe blade with the name of Hermenegildo Arruga, a noted Barcelona eye surgeon. This 13 cm reusable steel knife is tied to traditional cataract incisions. It suits teaching and surgeons who prefer classic steel.

Two Great Names

Von Graefe set the pattern for the long, narrow cataract knife. Later, Arruga added his own refinements to many cataract tools. So this knife blends both traditions. The photos show its exact outline.

Arruga Variant Facts

• Size: 13 cm.
• Pattern: Graefe-Arruga.
• Reusable stainless steel.
• Ships non-sterile.

Arruga Version or Plain Graefe?

We stock both. The two share a length and a lineage. However, their blade details can differ. Therefore, compare the photos before you order.

Long Blades Bend Under Weight

So store the Arruga variant flat in a guard. Never stack trays on top of it. Also inspect the full length of the edge before use. A bent blade will not cut a clean line.

Showing Classic Cataract Steps

Teaching sessions often trace cataract surgery from old methods to new. This knife shows how surgeons once opened the eye. Then residents can compare it with modern small blades. The contrast makes the lesson stick.

Arruga’s Wider Legacy

Arruga also worked on retinal detachment and many cataract tools. So his name appears in several parts of eye surgery. In this knife, it marks a refined Graefe outline. Compare the photos to see the detail.
