STERiJECT™ Ophthalmic VLDS Needle
VLDS: Ophthalmic Low Dead Space
Our ophthalmic-cleared, low-dead-space needle, built to give back what a standard hub holds onto.
VLDS is TSK's low-dead-space needle line, and the only one with FDA 510(k) clearance for ophthalmic use in the United States. A low-dead-space hub, ophthalmic cannula and secure luer-lock connection work together, with each production lot tested for USP <789> particulate compliance and to a bacterial endotoxin limit of 0.2 EU per device. Availability varies by product code and region.

Engineering
Design features
-
01Low-dead-space hub
Designed to reduce medication retained at the needle connection after delivery. In bench testing, the VLDS hub retained 0.005 mL versus 0.042 mL for a tested conventional hub.
-
02Extra-thin-wall cannula & enlarged lumen
An enlarged internal diameter supports flow through fine-gauge configurations and can reduce the force required to move fluid through the cannula.
-
03360° external threading
Full circumferential engagement with a compatible luer-lock syringe for a secure connection.
-
04Hard polycarbonate hub
Rigid construction that resists hub deformation and needle movement under load.
-
05Sharp lancet bevel
Engineered for low penetration force; a proprietary coating supports glide and reduces vitreous drag.
-
06Ophthalmic quality pathway
Lot testing includes USP <789> particulate requirements and a bacterial endotoxin limit of 0.2 EU per device.
Externally threaded VLDS hub and ophthalmic cannula.
Quality
Ophthalmic quality controls
Every VLDS lot passes the same three checks before it ships.
-
Particulate control
Tested before release for USP <789> compliance.
-
Silicone oil management
Construction and handling assessed as a complete delivery system to manage droplet release.
-
Bacterial endotoxin testing
Tested to a limit of 0.2 EU per device.

Performance evidence
Bench results
Residual volume — 0.005 mL for the tested VLDS hub versus 0.042 mL for the tested conventional hub.
Penetration force — 33G STERiJECT ophthalmic needle showed a penetration force 0.014 N lower than the tested comparator.
Rigidity and flow — the tested 33G configuration showed a shorter bending distance and higher flow than its comparator.
Connection strength — 50 N pop-off force for the tested 34G configuration versus 39 N for its comparator.
These bench comparisons apply to the tested sizes, methods and comparators; they are not peer-reviewed clinical outcomes.
