Caliburn trocar systemS
In vitrectomy with the OS 4, the Caliburn trocar system ensures precise work with exceptionally sharp instruments. The lance-shaped blade is distinguished by its high piercing and cutting force. The razor-sharp Caliburn blade reduces the penetration force and leads to an optimal cutting geometry in the sclera. The thin tunnel incision enhances postoperative wound sealing.
The trocar with integrated sealing membrane prevents the leakage of BSS, air and oil, resulting in a constant IOP. With its holding power and optimal shaft length, the Caliburn trocar offers both safety and convenience.
Advantages of Caliburn trocar systems:
Postoperative wound tightness
- Smooth insertion of the trocar
- Integrated, double-slotted sealing membrane for
constant IOP during surgery
Patented infusion tube with snap lock for increased

The independent study proves that the lancet-pointed needle from the Caliburn trocas system has remarkable low piercing force buth high cutting force:
- 9 types of commercially available ophthalmic 23 G trocar system investigated
- Analysis of different designs and geometries
- Penetration force measurement
Twenty-three-gauge trocar systems with penetration force diagrams and cut images. The left row shows three back bevel
trocar systems from Geuder, Alcon, and Fritz Ruck. The middle row shows the back bevel from Oertli, the lancet bevel from
Oertli, and spear bevel from Alcon. The right row shows three spatula bevels from Eyetech, DORC, and Bausch and Lomb1.
