Abstract：
Surgical treatment of eyelid margin lesions is challenging, and few studies focused on laser therapy of such type of lesions. To evaluate the safety and effectiveness of ultrapulse CO2 laser treatment under a microscope for benign eyelid margin lesions, we performed microscopic ultrapulse CO2 laser treatment win 132 patients with benign eyelid margin lesions for cosmetic reasons. Measurements included cosmetic results, complications and patients\' satisfaction. Eighty lesions involved the gray line and 24 lesions were in the lacrimal region. All patients achieved satisfactory cosmetic and therapeutic outcomes. Eyelid contour recovered well with no scar and no malposition. No secondary epiphora was noted after the lesions adjacent to the lacrimal punctum were removed. At the end of follow-up, only 2 patients had mild hypopigmentation and only 1 patient required repeat laser therapy for recurrence. It turned out that ultrapulse CO2 laser treatment under a microscope is a dependable, safe, and effective method for the treatment of benign eyelid margin lesions. It is an excellent alternative to traditional surgery, especially for lesions involving the gray line or positioned in proximity to the lacrimal punctum. It is beneficial for simplifying the treatment, improving the cosmetic result, and maintaining eyelid function.
摘要：
眼睑边缘病变的手术治疗具有挑战性，很少有研究集中在这种类型的病变的激光治疗。评估显微镜下超脉冲CO2激光治疗眼睑良性边缘病变的安全性和有效性。我们进行了显微超脉冲CO2激光治疗，共132例因美容原因出现眼睑边缘良性病变的患者。测量包括美容结果，并发症和患者满意度。80个病灶累及灰线，24个病灶位于泪道区。所有患者均取得满意的美容和治疗效果。眼睑轮廓恢复良好，无疤痕，无错位。在去除泪点附近的病变后，未发现继发性溢泪。在后续行动结束时，只有2例患者出现轻度色素沉着减退,只有1例患者因复发需要重复激光治疗.事实证明，显微镜下的超脉冲CO2激光治疗是可靠的，安全,治疗眼睑良性边缘病变的有效方法。这是传统手术的绝佳替代品，尤其是涉及灰线或位于泪点附近的病变。它有利于简化治疗，改善美容效果，保持眼睑功能。
