Purpose We describe a scleral suture fixation technique for dislocated plate haptic toric intraocular lens (IOL) implantation. Materials and methods A double-armed 10-0 straight polypropylene suture was passed into the eye from the sclera (2 mm away from the limbus). A suture needle was passed through the hole on the corner of the IOL and pulled out from the paracentesis with a 27-gauge needle. Afterward, the suture needle was reinserted from the same paracentesis and then removed from the eye with the help of a 27-gauge needle entering the eye from a nearby point to the first scleral entrance. The needle was passed through the end of the loop and pulled slightly to initiate the formation of a cow-hitch knot. The same procedure was applied to the other hole on the plate haptic. Both sutures were adjusted and fixed to the sclera with a Z suture. Results No complications were observed and at the follow-up visits, uncorrected visual acuity was 0.8 with decimal. Conclusion Axial, sagittal, and rotational stability rules are taken into consideration, scleral fixation surgery for a dislocated plate haptic foldable toric IOL is an alternative method to eliminate astigmatic refractive error.
目的 我们描述一种用于脱位的平板襻散光人工晶状体(IOL)植入的巩膜缝线固定技术。材料与方法 一根双臂10-0直聚丙烯缝线从巩膜(距角膜缘2mm处)穿入眼内。缝线针穿过IOL角上的孔,并用27号针从穿刺口拉出。之后,缝线针从同一穿刺口重新插入,然后在一根27号针从距第一个巩膜穿刺口附近的点进入眼内的帮助下从眼内取出。针穿过环的末端并轻轻拉动以开始形成双套结。对平板襻上的另一个孔进行相同操作。两根缝线均进行调整并用Z形缝线固定于巩膜。结果 未观察到并发症,随访时未矫正视力为小数视力0.8。结论 考虑到轴向、矢状和旋转稳定性规则,脱位的平板襻可折叠散光IOL的巩膜固定手术是消除散光屈光不正的一种替代方法。
