简要总结
This study aimed to compare the safety and efficacy of vitrectomy probe with different shaft lengths in vitreoretinal surgery of highly myopic patients. In this randomized controlled study, highly myopic patients who had axial length more than 26 mm and needed vitreoretinal surgery will be enrolled. The enrolled patients will be randomized into "30 mm shaft length group"(trial group) and "27mm shaft length group"(controlled group). We will compare the rate of wound leakage, hypotony, subconjunctival hemorrhage, probe bending, trocar removal, and endophthalmitis between the two groups. We would like to evaluate the efficacy and safety of the 30 mm shaft length vitrectomy probe.

结局指标
主要结局
operation time
时间窗: intra-operative
record the operation time and time of core vitrectomy
trocar removal rate
时间窗: intra-operative
trocar removal would be performed if the length of vitrectomy probe was not adequate
次要结局
- instrument bending(intraoperative)
