Two-arm, mono-center, prospective, interventional comparative case study to compare postoperative recovery between the 27G and larger gauge surgical approach.

A prospective randomized comparison of postoperative recovery between 27-gauge and larger gauge surgical approaches to evaluate efficiencies and postoperative outcomes of the surgical gauges. Fifty patients who were scheduled to undergo pars plana vitrectomy (PPV) for floaters or macular surgery were treated with either 27-gauge or 23-gauge techniques and assessed for efficiency of the procedures as well as a variety of postop indicators of pain and inflammation.
