Abstract：
Lens dislocation is a significant complication after cataract surgery. Scleral fixation of 3-piece intraocular lens provides favorable visual outcome and can spare patients the need for lens exchange. Two patients presented with dislocated 3-piece lenses implanted over 10 years earlier. Both patients underwent pars plana vitrectomy and dropped lens rescue with scleral fixation. Postoperatively, the lens optic was found flipped nearly 90° at the optic-haptic junctions secondary to fluid-air exchange performed during vitrectomy. Both patients underwent intraocular lens exchange with a four point sclera fixated lens. Our study found that air tamponade is better avoided during rescue of old dislocated 3-piece lens implants. Intraocular lens exchange is preferred, when possible, to avoid complications associated with old dislocated lenses. Larger studies are needed to determine the effect of time on dislocated lens implants materials.
摘要：
晶状体脱位是白内障术后的重要并发症。3件式人工晶状体的巩膜固定提供了良好的视觉效果，并且可以使患者无需更换晶状体。两名患者在10年前植入了脱位的三片镜片。两名患者均接受了平坦部玻璃体切除术和巩膜固定术的晶状体抢救。术后,在玻璃体切除术期间,晶状体光学器件在光学-触觉交界处发生了近90°的翻转.两名患者均接受了四点巩膜固定晶状体的人工晶状体交换。我们的研究发现，在抢救旧的脱位三片晶状体植入物时，最好避免空气填塞。人工晶状体更换是首选，如果可能,以避免与旧脱臼镜片相关的并发症。需要更大的研究来确定时间对脱位晶状体植入物材料的影响。
