To compare results of a novel "conjunctival frill/smile incision" on surgically induced astigmatism (SIA) and patient discomfort vs conventional trabeculectomy in the initial postoperative period.
Sixty trabeculectomy cases were subjected to either conjunctival frill incision, performed 1.5-2.0 mm from the limbus (study group) or conventional fornix-based conjunctival flap (control group). Corneal astigmatism and suture-induced discomfort were assessed by keratometry and a self-devised patient questionnaire, respectively.
Both groups generated a "with the rule" SIA, which was 1.77 vs 2.42 at 1 week and reduced to 1.27 vs 1.8 in the study vs control group, after removal of sutures - both scleral flap releasable and conjunctival at 1 month. Patient discomfort score revealed enhanced comfort in 37% of patients (study group) vs 17% (control group) during the early postoperative period. After 1 month of surgery, good comfort was regained in all cases.
This novel suturing technique results in reduced SIA, patient discomfort during the 1 month after trabeculectomy.
比较新型“结膜皱襞/微笑切口”与传统小梁切除术在术后早期对手术诱导性散光（SIA）和患者不适的影响。
60 例小梁切除术患者分别接受结膜皱襞切口（研究组）或传统穹隆结膜瓣（对照组）。通过角膜曲率计评估角膜散光，通过自行设计的患者问卷评估缝线引起的不适。
两组均产生“规则性”SIA，术后 1 周分别为 1.77 和 2.42，拆除缝线后分别为 1.27 和 1.8，在研究组和对照组中，1 个月时均为巩膜瓣可松解和结膜。患者不适评分显示，在术后早期，37%的患者（研究组）比 17%的患者（对照组）更舒适。术后 1 个月，所有病例均恢复良好的舒适度。
这种新型缝线技术可减少 SIA 和小梁切除术后 1 个月内的患者不适。
