To evaluate a novel surgical technique for transscleral fixation of the intraocular lens (IOL) with four hollow haptics using 8-0 polypropylene suture looping and overhand knot.
An 8-0 polypropylene suture was tied to a 10-0 polypropylene suture with an overhand knot. One set of 8-0 polypropylene suture was then passed through the IOL four haptics. The suture knot was buried by rotating into the sclera tunnel. Best-corrected visual acuity, intraocular pressure, and complications were determined.
The IOLs were fixed with using an 8-0 polypropylene suture in 13 eyes of 11 patients with aphakia and dislocated crystalline lens. The mean preoperative corrected distance visual acuity was 0.71 ± 0.58 logarithm of the minimum angle of resolution (Snellen 20/103), and it improved to 0.24 ± 0.25 logarithm of the minimum angle of resolution (Snellen 20/35) at the final follow-up ( P < 0.05). No vitreous hemorrhage, hypotony, suture exposed, and pupillary capture of the IOL were observed in any of the patients.
The authors have developed a new technique for transscleral IOL fixation with one set of an 8-0 polypropylene suture tied to a 10-0 polypropylene suture with an overhand knot. The overhand knot offers the opportunity to use an 8-0 polypropylene suture for the long-term safety and may not require the surgeon to learn any new technique.
评估一种使用 8-0 聚丙烯缝线双套结环套和反手结经巩膜固定眼内透镜（IOL）的四个空心襻的新手术技术。
用反手结将 8-0 聚丙烯缝线与 10-0 聚丙烯缝线系在一起。然后将一组 8-0 聚丙烯缝线穿过 IOL 的四个襻。将缝线结旋转埋入巩膜隧道中。确定最佳矫正视力、眼压和并发症。
11 例无晶状体眼和晶状体脱位患者的 13 只眼使用 8-0 聚丙烯缝线固定 IOL。术前平均矫正远视力为 0.71 ± 0.58 最小角分辨率对数（Snellen 20/103），最终随访时提高至 0.24 ± 0.25 最小角分辨率对数（Snellen 20/35）（P < 0.05）。所有患者均未观察到玻璃体积血、低眼压、缝线外露和瞳孔捕获 IOL。
作者开发了一种新的经巩膜 IOL 固定技术，即用 8-0 聚丙烯缝线穿过 10-0 聚丙烯缝线并系上反手结。反手结提供了使用 8-0 聚丙烯缝线进行长期安全固定的机会，并且可能不需要外科医生学习任何新技术。
