Katena K1-5950 Smirmaul Eye Speculum

Katena Smirmaul Eye Speculum | 15mm Solid Blades | K1-5950

The Katena K1-5950 is a high-precision ophthalmic instrument engineered for superior eyelid retraction during cataract surgery, corneal procedures, and intravitreal injections. Following the specialized Smirmaul pattern, this speculum features solid 15mm blades and a robust mechanical frame designed to provide an unobstructed surgical field while ensuring maximum patient safety.

Unlike standard wire specula, the Smirmaul design incorporates individually adjustable blades. This allows the surgeon to customize the tension and opening width for each eyelid independently, accommodating asymmetrical orbital anatomy or specific procedural requirements with a degree of control not possible with spring-tension models.

Key Specifications

• Manufacturer: Katena

• Model / REF: K1-5950

• Series / Pattern: Smirmaul

• Instrument Type: Adjustable Eye Speculum

• Blade Type: Solid (Non-fenestrated)

• Blade Size: 15 mm

• Overall Length: 6 inches (approx. 150 mm)

• Material: Surgical Grade Stainless Steel

• Mechanism: Independent Screw-Adjustment

Technical & Clinical Advantages

• Solid Blade Protection: The 15mm solid blades are designed to fully sequester the eyelashes and lid margins from the surgical site. This significantly reduces the risk of surgical site contamination (endophthalmitis) by preventing lash interference with instruments or implants.

• Independent Adjustment: The dual-screw mechanism allows for the independent expansion of the superior and inferior blades. This is particularly advantageous in patients with tight brow structures or deep-set eyes (enophthalmos) where uniform tension may be insufficient.

• Non-Reflective Satin Finish: The high-grade stainless steel is treated with a satin finish to minimize glare under the intense coaxial lighting of the operating microscope, reducing surgeon eye fatigue.

• Atraumatic Blade Geometry: The edges of the 15mm blades are precision-milled and polished to be perfectly smooth, distributing pressure evenly across the conjunctival fornix to prevent localized edema or bruising.

• Surgical-Grade Durability: Forged to Katena’s exacting standards, the K1-5950 maintains its thread precision and mechanical alignment through thousands of high-temperature sterilization cycles.

Applications

• Cataract & IOL Surgery: Providing a stable, protected field for phacoemulsification and lens implantation.

• Corneal Surgery: Essential for keratoplasty and pterygium excision where the ocular surface must remain isolated.

• Glaucoma Procedures: Exposure for trabeculectomies or tube shunt placements.

• Intravitreal Injections: Secure lid retraction for the administration of anti-VEGF therapies.

Condition & Quality Assurance

• Status: Used — In Excellent Condition.

• Integrity: The adjustment screws move fluidly with consistent resistance. The solid blades are perfectly aligned and free of nicks, pitting, or surface oxidation.

• Maintenance Requirement: As a reusable ophthalmic instrument, this speculum must undergo a validated decontamination and sterilization cycle (standard steam autoclave) in accordance with hospital protocols and Katena’s Instructions for Use (IFU) prior to clinical use in 2026.

• Professional Standards: With over 25 years of experience in specialized optics and surgical hardware, Primis Medical ensures all ophthalmic instruments are inspected for mechanical safety and micro-surface integrity.

• Secure Logistics: Shipped in specialized protective packaging to ensure the adjustment threads and blade alignment remain pristine during transit.

• Fast Dispatch: Ships within 1 business day.
