The aim was to introduce the application of a simple technique using high-frequency radiowave electrosurgery in the management of superior limbic keratoconjunctivitis (SLK).
This study is a prospective, noncomparative, interventional case series analysis. Seven patients (9 eyes) with SLK were recruited from the outpatient clinic of the Department of Ophthalmology, Severance Eye Hospital and Kangbuk Samsung Hospital, Seoul, Korea. On the superior bulbar conjunctiva, multiple ablations were performed using a high-frequency radiowave electrosurgical unit (Ellman Surgitron Dual Frequency RF; Ellman International, Inc, Hewlett, NY) with the lowest power setting of 1 (of 100) in the cutting mode. The operation was completed when the operator found no redundant portion on the superior bulbar conjunctiva.
After the surgery was performed, all the patients had mild to moderate superior conjunctival injection and swelling at the operating area. One month postoperatively, slit-lamp examinations revealed a smooth conjunctival surface without remarkable hyperemia. The symptoms were significantly improved in all eyes. Follow-up Fourier domain optical coherence tomography images showed a decrease of the space between subconjunctival tissue and sclera. No notable complications were observed.
This study demonstrated that high-frequency radiowave electrosurgery is a simple, safe, and effective first-line surgical treatment modality for refractory SLK patients with conjunctivochalasis.
介绍一种使用高频电波电外科技术治疗上领性边缘性角膜结膜炎（SLK）的应用。
本研究为前瞻性、非对照、干预性病例系列分析。从韩国首尔 Severance 眼科医院和 Kangbuk Samsung 医院的眼科门诊招募了 7 名（9 只眼）SLK 患者。在球结膜上，使用高频电波电外科单元（Ellman Surgitron Dual Frequency RF；Ellman International，Inc，Hewlett，NY）以 1（100 档中的 1 档）的最低功率设置在切割模式下进行多次消融。当操作者发现球结膜上没有多余部分时，手术即完成。
手术后，所有患者均有轻度至中度上结膜充血和手术区域肿胀。术后 1 个月，裂隙灯检查显示结膜表面光滑，无明显充血。所有眼睛的症状均显著改善。后续傅里叶域光学相干断层扫描图像显示，结膜下组织与巩膜之间的空间减少。未观察到明显的并发症。
本研究表明，高频电波电外科是治疗伴有结膜松弛的难治性 SLK 患者的一种简单、安全、有效的一线手术治疗方法。
