New coaxial system for manual extracapsular cataract surgery

Area of Science:

• Ophthalmic Surgery
• Surgical Instrumentation
• Medical Device Design

Background:

• Manual extracapsular extraction is a common ophthalmic surgical procedure.
• Existing irrigation/aspiration systems can involve complex setups and numerous components.
• Reducing intraoperative manipulations is crucial for surgical efficiency and patient safety.

Purpose of the Study:

• To present a novel partially disposable coaxial system for manual extracapsular extraction.
• To highlight the design features that simplify the surgical workflow.
• To compare the proposed system with existing partially disposable irrigation/aspiration systems.

Main Methods:

• Development of a partially disposable coaxial system.
• Incorporation of a flexible outer sleeve to accommodate straight and curved cannulas.
• Elimination of traditional connector tubings and non-Luer-locked fittings.

Main Results:

• The system offers both straight and curved irrigation/aspiration cannulas.
• The flexible outer sleeve facilitates adaptability during surgery.
• Significant reduction in intraoperative manipulations compared to other systems was achieved.

Conclusions:

• The presented partially disposable coaxial system offers a streamlined approach to manual extracapsular extraction.
• The innovative design enhances surgical efficiency by minimizing procedural steps.
• This system represents an advancement in ophthalmic surgical instrumentation.
