    A novel 3D-printed syringe handle allows one-handed anterior chamber paracentesis, improving ergonomics and safety during the procedure.

  • 2

    The device enables plunger retraction with one finger while stabilizing the globe with the other hand, reducing the risk of complications.

  • 3

    In a randomized controlled study, the novel method achieved a median aspirated volume of 120 µL, significantly lower than the conventional method's 200 µL.

  • 4

    Procedure time was reduced by a median of 8.8 seconds with the novel device, although this reduction was not statistically significant.

  • 5

    Post-procedure surveys indicated high participant satisfaction with the novel device, with most feeling more confident about its safety.
