The Instrument
One hook. Two directions. A complete trabeculotomy.
A single entry into the chamber
The dual-hook geometry reduces the need for multiple entries into the anterior chamber, keeping every pass controlled.
Trabeculotomy in one single time
Built to complete the trabeculotomy in one sitting — a streamlined surgical process from first engagement to final pass.
Confidence for every surgeon
Deliberately easy to use — as reassuring for the novice surgeon as it is efficient for the seasoned MIGS specialist.
Key Features
Engineered down to the last micron
Five deliberate design decisions, each one answering a problem met at the operating table.
01
Angulated Neck
Reaches the trabecular meshwork at the correct working attitude through a standard paracentesis.
02
Fine Shaft
A slender profile that keeps the anterior chamber stable and the gonioscopic view unobstructed.
03
Two Opposing Cutting Edges
Cut on both directions of travel — the heart of the dual design.
04
Ergonomic Ribbed Handle
Secure, tactile control through the entire pass.
05
Fixed-Angle Working Tip
A reproducible angle of engagement with Schlemm's canal — case after case.

In Theatre
The proof is on the scan
- 1
Visualise the angle
Under gonioscopy, bring Schlemm's canal into clear view.
- 2
Engage with the fixed-angle tip
The angulated neck seats the working tip into the canal at a reproducible angle.
- 3
Incise in one direction
One cutting edge opens the trabecular meshwork along the pass.
- 4
Reverse to complete
The opposing edge completes the trabeculotomy on the return — no instrument exchange, one entry.
