What this Trial Is About
Researchers are comparing two techniques used for active silicon oil removal (SOR) in patients who have silicon-filled eyes and are prepared for SOR. The study aims to evaluate the efficiency and safety of these methods during and after surgery. This trial involves 540 eyes from 505 patients, including some with both eyes treated. All participants undergo SOR using a 23-Gauge pars plana vitrectomy (PPV). The eyes are divided into two groups based on the surgical technique used: Group A uses a vitrectomy machine with a specific SO extraction program, while Group B uses a modified spring loaded syringe. Both techniques are actively compared to assess their outcomes. Participants will be monitored for complications during the surgical procedure and up to three months afterward. The study includes randomized allocation and double masking to ensure unbiased results. Researchers will evaluate safety and effectiveness through these follow-up assessments, with the total participation time covering the surgery and postoperative period.
