We describe a method that enables the introduction of 2 suture loops for scleral fixation of an intraocular lens (IOL) by a single ab externo procedure. A long needle carrying a polypropylene suture loop is inserted through the scleral fixation site and docked with a hollow needle inserted through the opposite fixation site. The hollow needle pulls the suture needle out, but the suture loop end is left external. Another polypropylene suture loop is placed through the first loop. As the first (leading) suture is pulled, the second (trailing) suture is drawn into the eye. The suture loops are retrieved through the main incision. The IOL haptics are secured with a polypropylene loop by cow hitches. After the IOL is placed in the eye, the sutures are fixated to the sclera. This technique enhances efficiency and control during the introduction of suture loops for scleral fixation of IOLs.
我们描述了一种方法，通过单次外路手术即可在巩膜固定眼内透镜（IOL）时引入 2 个缝线环。一根长针携带一个聚丙烯缝线环穿过巩膜固定部位，并与穿过对面固定部位的空心针对接。空心针将缝线针拔出，但缝线环的末端留在外部。另一个聚丙烯缝线环穿过第一个环。当拉动第一个（主导）缝线时，第二个（尾随）缝线被拉入眼睛。缝线环通过主切口取出。IOL 襻通过牛鼻环用聚丙烯环固定。IOL 放置在眼睛中后，将缝线固定在巩膜上。这种技术可提高引入缝线环以巩膜固定 IOL 时的效率和控制性。
