Summary

The active-fluidics system better protected retinal vasculature and microcirculation after cataract surgery compared to gravity-fluidics. This system improved surgical efficacy while preserving retinal thickness and vessel density.

Area of Science:

Ophthalmology
Retinal Imaging
Surgical Technology

Background:

Cataract surgery can impact retinal microcirculation.
Evaluating fluidics systems is crucial for optimizing surgical outcomes and patient safety.

Purpose of the Study:

To assess early changes in retinal microcirculation following uncomplicated cataract surgery.
To compare the effects of active-fluidics versus gravity-fluidics systems on the retina.

Main Methods:

A randomized study comparing active-fluidics and gravity-fluidics systems in cataract surgery.
Optical coherence tomography angiography (OCTA) was used to evaluate retinal microcirculation and thickness.
Follow-up assessments were conducted at 1, 7, 30, and 90 days post-surgery.

Main Results:

The active-fluidics group showed lower cumulative dissipated energy, estimated fluid usage, and aspiration time.
Superficial parafoveal vessel density increased post-surgery in both groups, with more fluctuation in the gravity-fluidics group.
Retinal thickness in the macular region significantly changed in the gravity-fluidics group but remained stable with active-fluidics.

Conclusions:

Gravity-fluidics infusion systems can disturb retinal microcirculation and thickness post-cataract surgery.
The active-fluidics system enhances surgical efficiency and protects retinal vasculature during the procedure.
