To present an electrocoagulation fixation technique for one-piece intraocular lens (IOL) scleral flapless fixation with sutures without knots.
First of all, after repeated tests and comparisons, we chose 8-0 polypropylene suture as the material for electrocoagulation fixation of one-piece IOL haptics because of its proper elasticity and size. A transscleral tunnel puncture at the pars plana was performed using an arc-shaped needle with 8-0 polypropylene suture. The suture was subsequently guided out of the corneal incision by a 1-mL syringe needle and then guided by the needle into the inferior haptics of the IOL. The suture was cut off and heated into a shape of a probe with a spherical tip using a monopolar coagulation device to prevent slippage from the haptics.
In the end, 10 eyes underwent our new surgical procedures, and the average operation time was 42.5 ± 12.4 minutes. At the 6-month follow-up, seven of 10 eyes achieved significant vision improvement and nine of 10 kept the implanted one-piece IOL stable in the ciliary sulcus. No serious intraoperative/postoperative complications were observed.
The electrocoagulation fixation was a safe and effective alternative technique for previously implanted one-piece IOL scleral flapless fixation with sutures without knots.
介绍一种采用无结缝线进行一次性人工晶状体(IOL)巩膜瓣下无结缝线固定的电凝固定技术。
首先,经过反复测试和比较,我们选择 8-0 聚丙烯缝线作为一次性 IOL 襻电凝固定的材料,因为它具有适当的弹性和尺寸。在平部行巩膜隧道穿刺,使用带 8-0 聚丙烯缝线的弧形针。然后,将缝线通过 1mL 注射器针头引导出角膜切口,再通过针头引导至 IOL 的下襻。将缝线剪断并使用单极电凝装置加热成带有球形尖端的探针形状,以防止从襻上滑脱。
最终,10 只眼接受了我们的新手术程序,平均手术时间为 42.5±12.4 分钟。在 6 个月的随访中,10 只眼中有 7 只视力显著改善,10 只眼中有 9 只保持植入的一次性 IOL 在睫状沟内稳定。未观察到严重的术中/术后并发症。
电凝固定是一种安全有效的替代技术,适用于先前植入的一次性 IOL 巩膜瓣下无结缝线固定。
