We describe a modified method for scleral fixation of posterior chamber intraocular lenses (IOLs). A double-armed, 10-0 polypropylene (Prolene) suture on a curved long needle is passed through a groove in the sclera and retrieved within the barrel of a bent 25-gauge needle through the opposite groove. Double transscleral passages enable 4-point fixation and provide better stability and centration. Knots are buried completely in the scleral groove. In a series of 10 cases, the IOLs were well centered, no sutures protruded from the scleral groove, and the vision in all eyes improved. In 1 case, a ciliary hemorrhage occurred during insertion of the 25-gauge needle, but the bleeding stopped after ocular pressure reform. This technique is easy to perform, improves centration and stability of the IOL, and avoids suture exposure.
我们描述了一种改良的后房型人工晶状体(IOL)巩膜固定方法。一根弯曲长针上的双臂10-0聚丙烯(普理灵)缝线穿过巩膜上的一个凹槽,并通过相对的凹槽在一根弯曲的25号针管内取出。双巩膜通道实现四点固定,并提供更好的稳定性和居中效果。结完全埋入巩膜凹槽中。在一系列10例病例中,人工晶状体居中良好,无缝线从巩膜凹槽中突出,所有患眼视力均有改善。1例在插入25号针时发生睫状体出血,但眼压恢复后出血停止。该技术操作简便,可提高人工晶状体的居中效果和稳定性,并避免缝线外露。
