About
Precision injection technology for ophthalmic care and drug delivery
TSK develops, manufactures, and supports the STERiJECT product line.
We bring clinical insight, formulation science and precision manufacturing into the same room, early enough to change the device, not just approve it.
Global footprint
Manufactured in Tochigi, Japan. Around it sit regional entities and distribution partners serving clinicians in more than sixty countries.
How we work
Three commitments that decide how our devices get made
Clinicians and formulation scientists help shape our devices before tooling is cut, so problems seen at the point of care get solved in the geometry.
Thin-wall bores, low-dead-space hubs and refined tip geometries each exist because a clinical outcome demanded them, not the other way around.
Manufactured and documented to the regulatory standards our markets require. Precision isn't a feature of our products; it's the condition of making them.
The company
TSK Laboratory International develops and manufactures specialty needles and medical devices, holding multiple patents across both needle materials and designs. Our products are used daily by clinicians in ophthalmology, interventional radiology, aesthetics and dentistry.
STERiJECT™ is our injection device brand. In ophthalmology, it exists to solve a specific problem: the eye deserves a needle designed for the eye.
TSK’s development work spans materials, needle and hub design, cannula geometry and related device engineering.
Quality assurance, inspection, documentation and regulatory preparation are integrated into TSK’s development and manufacturing support model.
TSK emphasizes direct feedback from clinicians and long-term work with medical, pharmaceutical and device partners as inputs to product development.
Next step
STERiJECT connects a defined ophthalmic product portfolio with the engineering, manufacturing and quality capabilities of TSK Laboratory. For a clinical, research or development requirement, contact TSK to discuss the exact device, documentation and regional pathway.
