Several techniques are used to reposition dislocated intraocular lenses (IOLs). Most place a suture loop around the end of the haptic. However, in cases of a dislocated capsular bag containing the IOL, a dislocated IOL with a large haptic, or a miotic pupil, it is not easy to see the haptic ends to place the suture loop. We describe a scleral fixation technique that uses 2 corneal tunnels. A double-armed 10-0 polypropylene suture loop can be introduced through 1 corneal tunnel and placed around any accessible part of the haptic with the help of a bent 26 gauge needle. This modified technique is an easy and effective way to reposition the IOL.
有几种技术用于重新定位脱位的人工晶状体（IOL）。大多数方法是在襻的末端放置一个缝线环。然而，在包含IOL的囊袋脱位、襻较大的IOL脱位或瞳孔缩小的情况下，很难看到襻的末端来放置缝线环。我们描述了一种使用2个角膜隧道的巩膜固定技术。一个双臂10-0聚丙烯缝线环可通过1个角膜隧道引入，并在一根弯曲的26号针的帮助下放置在襻的任何可触及部分周围。这种改良技术是重新定位IOL的一种简单有效的方法。
