The patients were divided into four groups based on four types of vitrectomy probes that are currently used in surgery: 23–7500 (UltraVit, Alcon Laboratories; 23-gauge 7,500 CPM), 23–7500 (UltraVit 25-gauge 7,500 CPM), 25–10K (Advanced UltraVit, Alcon Laboratories; 25-gauge 10,000 CPM), and 27–10K (Advanced UltraVit 27-gauge 10,000 CPM). For each group, data were collected and organized in terms of axial length measured using partial coherence interferometry (IOLMaster 700, Carl Zeiss Meditec), vitrectomy time, number of sutures performed, the occurrence of iatrogenic retinal breaks during surgery, postoperative hypotony (below 6 mmHg), retinal detachment, endophthalmitis, and other complications. The vitrectomy time was defined as the time taken to remove the vitreous within the maximum visible range using a noncontact wide angle viewing system (Resight, Carl Zeiss Meditec) without indentation. The time taken to change instruments and the time spent on other procedures during surgery, such as PVD induction and removing membranes, were excluded from the vitrectomy time.
