目的：探讨睑缘切口联合浮桥技术在上睑下垂患者治疗中的应用效果，分析其对患者上睑缘角膜映光点距离(MRD1)及眼部美学效果的影响。

方法：前瞻性研究。本研究选取2023年1月至2025年7月在本院眼科接受治疗的上睑下垂患者，将其分为观察组与对照组。对照组患者接受常规重睑切口提上睑肌腱膜缩短术治疗，观察组采用睑缘切口联合浮桥技术进行提上睑肌腱膜缩短术。对两组患者的手术相关指标、上睑下垂矫正效果、美学效果、眼部功能指标以及术后并发症、复发率进行对比分析。

结果：本研究纳入上睑下垂患者100例100眼，观察组与对照组各50例50眼。观察组年龄27.33±5.32岁，男20例，女30例。对照组年龄27.64±4.66岁，男24例，女26例。相较于对照组，观察组手术时间有所延长，但术后消肿时间与自然恢复时间均更短，矫正率更高(均P<0.05)。术后3 mo，观察组VSS评分、POSAS评分均低于对照组，而眼睑弧度、眼睑高度对称性评分、PFH、MRD1、睑裂大小、上睑提肌肌力均高于对照组(均P<0.05)； 两组并发症、复发发生率无显著差异(均P>0.05)。

结论：睑缘切口联合浮桥技术治疗上睑下垂，尽管手术时间稍长，但能缩短术后恢复周期，有效改善患者MRD1指标及眼部功能，提升矫正效果与眼部美学质量，且并发症发生率较低，安全性有保障。

METHODS:Prospective study. This study enrolled patients with blepharoptosis treated at the Department of Ophthalmology of the hospital between January 2023 and July 2025, who were assigned to either an observation group or a control group. The patients in the control group received levator aponeurosis shortening surgery through conventional double-eyelid incision, while the patients in the observation group underwent levator aponeurosis shortening surgery using the eyelid margin incision combined with floating bridge technique. Subsequently, the surgical-related indicators,the correction effect of ptosis, the aesthetic effect, the ocular function indicators, the postoperative complication occurrence rate, and recurrence rate were compared and analyzed between two groups.

RESULTS:A total of 100 patients(100 eyes)with blepharoptosis were enrolled in this study, with 50 patients(50 eyes)in the observation group and 50 patients(50 eyes)in the control group. The observation group had a mean age of 27.33±5.32 y, including 20 males and 30 females. The control group had a mean age of 27.64±4.66 y, including 24 males and 26 females. Compared with the control group, the operative time of the observation group was longer, the postoperative swelling resolution time and natural recovery time were shorter,and the correction rate was higher(P<0.05). Three months after the surgery, the VSS score and POSAS score of the observation group were lower than those of the control group, while the scores for eyelid curvature, symmetry of eyelid height, and the PFH, MRD1, palpebral fissure size, and upper eyelid levator muscle strength were all higher than those of the control group(all P<0.05). However, there was no significant difference in postoperative complication occurrence rate and recurrence rate between two groups(all P>0.05).

CONCLUSION:The combined use of eyelid margin incision and floating bridge technique for treating ptosis results in slightly longer operation time, but it can shorten the postoperative recovery period, effectively ameliorate the MRD1 and ocular function of patients, and enhance the correction effect and aesthetic quality of the eyes. In addition, it has a low incidence of complications and guaranteed safety.
