To define a modified flap suture approach and evaluate its effectiveness.
Clinical data of patients undergoing trabeculectomy with modified parallel suture technique () were compared to patients operated with classical flap suture technique (). In the modified technique, two parallel sutures (one tight and one loose) are placed simultaneously in one of the flap corners with the aim of obtaining a safety stitch when the tight one needs to be cut. Data from preoperative and postoperative visits at day 1, week 1, months 1, 3, 6 and year 1 were recorded from patient charts and compared between the groups.
In , seven eyes underwent laser suture lysis (LSL) between postoperative days 2 to 8 and in two eyes at days 29 and 37. No complication related to LSL was observed. Rate of postoperative hypotony decreased with the parallel suture approach (= .002). Number of eyes experiencing any of the complications related to hypotony was lower in (= .004). No significant difference was noted in the mean IOP between the groups (> .05 for all).
The modified approach with parallel suture technique was found to be effective and safe. By enabling early LSL, it provided more precise IOP modulation in the early postoperative period. Thus, in our series, the rate of hypotony and hypotony-related complications decreased, while the success of the surgery was preserved.
定义一种改良的瓣缝线方法并评估其效果。
将接受改良平行缝线技术（）的小梁切除术患者的临床数据与接受经典瓣缝线技术（）的患者进行比较。在改良技术中，在瓣的一个角同时放置两条平行缝线（一条紧缝线和一条松缝线），目的是在需要剪断紧缝线时获得安全缝线。从患者病历中记录术前和术后第 1、1 周、第 1、3、6 个月和第 1 年就诊时的数据，并在组间进行比较。
在 中，7 只眼在术后第 2 至 8 天行激光缝线松解术（LSL），2 只眼在第 29 和 37 天行 LSL。未观察到与 LSL 相关的并发症。术后低眼压发生率随着平行缝线方法降低（= .002）。发生与低眼压相关的任何并发症的眼数在 中较低（= .004）。两组间的平均眼压无显著差异（>.05 均）。
改良的平行缝线技术方法被证明是有效和安全的。通过早期行 LSL，可以在术后早期更精确地调节眼压。因此，在我们的系列中，低眼压和低眼压相关并发症的发生率降低，同时保留了手术的成功率。
