Study Summary

The purpose of this study is to compare the treatment day change between immediate postoperative and immediate preoperative intraocular pressure (IOP) between 27-gauge and 23-gauge vitrectomy instruments.

Primary Outcome

IOP (fluid pressure inside the eye) was assessed using the study specified tono-pen and measured in millimeters of mercury (mmHg). Change was defined as the difference between immediate postoperative IOP and immediate preoperative IOP. A greater change in IOP may indicate a less stable posterior chamber and/or a more invasive surgery.
