Ophthalmic viscosurgical devices (OVDs) protect the corneal endothelium during cataract surgery. Different OVD types exhibit unique behaviors, influencing fluid dynamics and endothelial protection during phacoemulsification.

Area of Science:

  • Ophthalmology
  • Surgical Technology
  • Biomedical Engineering

Background:

  • Cataract surgery, specifically phacoemulsification, has advanced significantly.
  • Corneal endothelium damage remains a concern during phacoemulsification.
  • Ophthalmic viscosurgical devices (OVDs) are used to protect ocular tissues.

Purpose of the Study:

  • To analyze the fluid dynamics of different ophthalmic viscosurgical devices (OVDs) in the anterior chamber during phacoemulsification.
  • To evaluate the protective effect of OVDs on the corneal endothelium.
  • To introduce and validate the "slit side view" method for observing OVD behavior.

Main Methods:

  • Experimental study using extracted porcine eyes.
  • OVDs stained with fluorescein were injected into the anterior chamber.

Related Experiment Videos

  • Phacoemulsification simulation performed on the iris plane using a slit lamp microscope.
  • OVD movement and fluid dynamics observed using the "slit side view" technique.

    • Main Results:

    • Cohesive OVDs were aspirated rapidly.
    • Dispersive OVDs showed gradual aspiration and irregular shapes, trapping air to protect the endothelium.
    • Viscoadaptive OVDs remained as a lump, allowing fluid flow and eventual aspiration.
    • Viscous dispersive OVDs detached from the endothelium with fluid infusion, indicating likely removal.

    Conclusions:

    • Different OVD types exhibit distinct behaviors during phacoemulsification.
    • The "slit side view" method effectively visualizes OVD fluid dynamics and interactions with ocular structures.
    • Understanding OVD behavior is crucial for optimizing corneal endothelial protection during cataract surgery.
