Castroviejo Calipers 20mm 9cm

The Castroviejo Calipers 20mm 9cm is constructed from German-grade surgical stainless steel with a passivated corrosion-resistant finish. The instrument measures 9 cm (approximately 3.5 inches) in overall length, significantly more compact than standard implant variants, with broad, flat curved arms joined at a central ball-joint pivot. The wide U-shaped open working ends spread bilaterally, and the graduated base scale runs from 0 to 20 mm in 1 mm increments. A knurled thumb-screw locks arm separation once the target measurement is captured.

This 9cm Castroviejo Caliper with 20mm Measuring Range reads measurements from both sides of the graduated base, accommodating left- and right-handed surgeons equally. The instrument tolerates full autoclave sterilization at 134°C and is compatible with ultrasonic cleaning and chemical disinfection. Passivation treatment guards the steel surface between sterilization cycles, and standard boil, performance, and shape quality-control tests are completed before dispatch, confirming consistent reusability across repeated procedures.

Ophthalmic surgeons use the Castroviejo Calipers 20mm 9cm during strabismus surgery and blepharoplasty procedures. In strabismus correction, the surgeon uses this ophthalmic measuring caliper to measure the exact muscle recession or resection distance on the extraocular muscle before cutting. In blepharoplasty, it measures the distance between the upper eyelid crease and brow or between the lid margin and lash line, ensuring symmetrical tissue excision on both sides.

Ophthalmic surgery demands instruments sized and calibrated for structures measured in single millimetres, and Leader Surgical sources instruments that meet exactly that requirement. This compact caliper reflects the kind of dimensional accuracy and material reliability that eye surgeons need when every measurement directly determines a patient’s visual outcome and anatomical symmetry.

How precise are the measurements?
Depending on the specific manufacturer, the scale is typically graduated in 0.5 mm or 1.0 mm increments. The ultra-fine tips (often 0.3 mm in diameter) allow for millimetric accuracy on delicate tissues
