Product Overview
The 558002 Mendez Degree Gauge is a hyper-precision ophthalmic measuring ring characterized by its compact 12mm internal diameter and clean 0° to 180° orientation calibrations. Designed in accordance with elite laser-assisted and micro-incision cataract surgery (MICS) protocols, this instrument acts as a critical reference template for the precise intraoperative placement of toric intraocular lenses (IOLs) and limbal relaxing incisions (LRIs). Forged from high-tensile surgical steel, the low-profile circular gauge features crisp, micro-etched reference lines calibrated at strict 10-degree intervals. The ring fits perfectly around the 12mm average surgical limbus, allowing the surgeon to perfectly translate pre-operative topographies into flawless surgical execution.
Key Features
-
High-Visibility 10° Calibrations: Features crisp, laser-engraved graduations from 0° to 180° marked precisely every 10 degrees. The high-contrast marking design allows the operator to effortlessly pinpoint, verify, and lock onto the target cylindrical axis under high microscope magnification.
-
Anatomical 12mm Internal Diameter: The ring architecture is hand-calibrated to a standard 12mm diameter. This specific measurement mirrors the average human corneal limbus, allowing the gauge to sit concentrically over the cornea without distorting or obscuring peripheral view fields.
-
Atemporal Axis Multi-Tasking: Engineered with a smooth, open-center configuration. It provides an unobstructed horizontal track, permitting secondary instruments—such as axis markers, capsulorhexis forceps, or alignment spatulas—to be introduced freely while maintaining an active degree reference.
-
Atraumatic Scleral Grounding: The posterior face of the ring is meticulously hand-beveled and polished smooth to ensure the delicate conjunctival, episcleral, and limbal vessels remain fully protected from pinching or localized friction trauma during centration.
-
Surgical-Grade Resilience: Manufactured from premium, hardened stainless steel. It is built to maintain its hyper-precise circular structural geometry, calibrated etchings, and anti-glare finish through thousands of high-heat sterilization cycles.
