Axis Marker (Green)
Engineered for exact visual axis localization in refractive and advanced IOL surgery, the Grene Axis Marker delivers crisp, accurate corneal alignment. Precision-crafted with a non-reflective finish and a fine ring tip for clean dye transfer without epithelial trauma.
Helveston Scleral Ruler
Engineered for accurate linear measurement along the contour of the globe, the Helveston Scleral Ruler provides exceptional precision for strabismus and scleral procedures. Precision-crafted with an anatomically curved profile and high-contrast millimeter scale for clear visibility under the microscope.
Mendez Degree Gauge
Engineered for exact rotational axis alignment during toric IOL implantation and astigmatism correction, the Mendez Degree Gauge delivers fine angular precision. Crafted with a glare-free satin finish and high-contrast laser-etched degree markings for clear intraoperative visualization under the microscope.
Braunstein Caliper
Engineered for exact scleral marking during intravitreal injections and vitreoretinal procedures, the Braunstein Caliper delivers fixed-distance accuracy from the limbus. Precision-crafted with dual-ended fixed spacing in glare-free surgical metal for rapid, repeatable intraoperative alignment.
Castroviejo caliper
Engineered for exact intraoperative tissue measuring in ophthalmic and micro-vascular surgery, the Castroviejo Caliper delivers exceptional fine-point accuracy. Precision-crafted with laser-etched millimeter markings and a secure thumb-lock mechanism for maximum stability under the surgical microscope.
Micro-Precision Gauging & Surgical Alignment Systems
In modern refractive, cataract, and strabismus surgery, microscopic accuracy in measurements is fundamental to achieving predictable visual outcomes. Whether sizing clear corneal incisions, measuring strabismus muscle recessions, or identifying astigmatic axes for toric IOL alignment, surgeons rely on measuring tools that offer sharp visual feedback, precise jaw alignment, and zero calibration drift.
Manufactured in strict adherence to ISO 13485 and CE quality standards, our Measuring Instruments collection is built from premium Medical Stainless Steel and Titanium Alloy. Featuring anti-glare satin finishes, hand-calibrated tips, and permanent, wear-resistant laser markings, these instruments provide unmatched stability, non-slip adjustment mechanisms, and effortless readability under high-power operating microscopes.
Key Models & Surgical Applications
-
Surgical Calipers: Precision calipers engineered for accurate linear measurement ($0.5\text{ mm}$ to $20\text{ mm}$) during corneal, scleral, and strabismus procedures, including the iconic Castroviejo Caliper (straight/curved) and the dual-ended Braunstein Caliper for fixed distance marking.
-
Scleral & Corneal Rulers: Ultra-slim, flexible measurement scales designed for precise scleral mapping and muscle displacement, featuring the specialized Helveston Scleral Ruler.
-
Toric & Astigmatism Markers: Angular measurement and alignment tools designed to map $0^\circ$ to $360^\circ$ meridians for flawless toric intraocular lens placement, featuring the Mendez Degree Gauge and micro-fine Axis Markers.
Why Choose Our Measuring Instruments?
-
Laser-Etched Readability: High-contrast, deeply etched degree and millimeter scales ensure crystal-clear visibility and long-term legibility without fading over time.
-
Hand-Calibrated Precision: Every caliper and gauge undergoes rigorous microscopic inspection to guarantee exact zero-point alignment and measurement accuracy.
-
Non-Reflective Finish: Matte and anodized surface treatments eliminate light reflections and glare under surgical microscope lighting.
-
Sterilization Ready: Engineered to preserve screw tension, gauge alignment, and mechanical smoothness through repeated steam autoclaving and EtO cycles.
