Area of Science:

  • Ophthalmology
  • Surgical Instrumentation

Background:

  • Cataract surgery requires effective removal of lens matter.
  • Current irrigation aspiration cannulas may have limitations in efficiency or safety.

Purpose of the Study:

  • To describe a novel, high-quality, reusable coaxial irrigation aspiration cannula.
  • To highlight the advantages of this cannula for cortical cleansing in cataract surgery.

Main Methods:

  • Development and description of a reusable coaxial irrigation aspiration cannula.
  • Evaluation of its performance characteristics, including inflow rate and pressure.

Main Results:

  • The cannula is characterized by its reusability and cost-effectiveness.
  • It provides rapid inflow at a low irrigation pressure, ensuring atraumatic cortical cleansing.
  • Facilitates faster and safer aspiration of soft lens matter.

Conclusions:

  • The described cannula is a superior tool for cortical cleansing during cataract surgery.
  • Its design offers significant advantages in terms of safety, efficiency, and cost.
