Precision Syringe

Patented index-finger control replaces the thumb-plunger — giving physicians measurably better precision in every injection.

A peer-reviewed study in Clinical Ophthalmology found 21% greater injection accuracy with the Suh Precision Syringe. Less variability in every injection means more consistent delivery and more predictable outcomes.

The Suh Precision Syringe replaces the thumb-plunger with a natural pencil grip. One hand controls the injection. The other stays free for stabilization, retraction, or patient management.

Standard Luer Lok compatibility. No capital equipment. No new training protocols. No workflow changes. A single-use consumable that works with your existing needles and procedures — switch in seconds.

For 170 years, every syringe has worked the same way: thumb on a plunger at the back of the barrel, inches from the injection site. The Precision Syringe moves the point of control forward — placing the index finger directly adjacent to the needle. It’s a fundamental structural change that produces a measurable clinical difference.

The peer-reviewed study, published in Clinical Ophthalmology (2019), measured plunger excursion across multiple operators and found a statistically significant 21% reduction in injection variability with the index-finger design.
