Product Overview
The Castroviejo Caliper is a foundational ophthalmic instrument characterized by its graduated measuring scale and a smooth-turning adjustment screw. This specialized tool features a measurement range of 0mm to 20mm, with the scale conveniently located on one side for immediate legibility under the surgical microscope. Forged from high-tensile surgical steel, it is the primary choice for surgeons who require a “liquid-smooth” mechanism to measure muscle recession distances during strabismus surgery, corneal graft sizes, or structural landmarks in plastic reconstruction.
Key Features
-
“Beast-Bite” 0mm to 20mm Scale: Engineered with an ultra-precise, single-sided scale graduated in 0.5mm increments. This provides the mechanical authority to verify millimetric dimensions instantly without shifting the lens or line of sight.
-
Thumbscrew Locking Mechanism: Features a micro-milled adjustment screw that glides with a “liquid-smooth” feel. Once set, it locks the caliper prongs securely in place, ensuring a “dead-lock” hold on the measurement during transfer.
-
Micro-Fine Measuring Tips: The distal prongs are hand-finished to exceptionally fine, pointed tips. This allows for high-precision placement against the limbus, sclera, or skin margins without obscuring the localized anatomy.
-
Ergonomic Balanced Frame: Designed with a lightweight, spring-tempered arch frame that provides immediate tactile feedback. The instrument balances perfectly in a pencil-grip, ensuring stable manipulation within tight periorbital spaces.
-
Surgical-Grade Resilience: Manufactured from premium, hardened stainless steel. It is built to maintain its calibration accuracy and prong alignment through thousands of high-heat sterilization cycles.
