Abstract

The invention concerns an improved tip (1) for oculistic surgery, particularly for the removal of cataract, having a proximal joint end (2) and a distal end (4), contacting the crystalline during the surgical intervention, wherein the distal end (4) contacting a corneal or sclera tissue is coated with an anti-friction treatment, based on carbon and tungsten carbide.

Claims

1. A tip for oculistic surgery, particularly for the removal of a cataract, said tip having a proximal joint end and a distal end, which contacts crystalline during a surgical intervention, wherein the distal end which contacts a corneal or sclera tissue is coated with an anti-friction treatment, based on carbon and tungsten carbide.

2. The tip according to claim 1, wherein said treatment is carried out by a PVD (Physical Vapour Deposition) technique.

3. The tip according to claim 1, wherein a thin layer of chromium (Cr₁) is applied during the treatment, to improve adhesion of the subsequent depositions.

4. The tip according to claim 1, wherein said proximal joint end is subjected to polishing.

5. The tip according to claim 1, wherein said end is shaped with different angles and geometry.
