A new method for intraocular lens (IOL) fixation in the scleral tunnel using two common 27G blunted needles and an ultrathin 30G needle with fewer intraocular manipulations was developed. Half-depth scleral flaps were prepared, and vertically angled sclerotomies were performed under each scleral flap, 2 mm from the limbs with a 20G microblade or a 26G needle. Two bent 27G blunted needles connected the sclerotomy and corneoscleral incisions. One haptic was inserted into this bent 27G blunted needle extraocularly and extruded through the sclerotomy site. Each haptic was inserted into the lumen of the preplaced ultrathin 30G needle and buried into the scleral tunnel. In this retrospective study, we reviewed the outcomes of this new technique in patients with at least 3 months' follow-up data. Iris capture of the IOL was not observed in any case, and IOL repositioning was not performed either. Astigmatism induced by intraocular aberration was almost as same as that with other methods. Our technique can be performed in any operation room without any extra instruments. This trial is registered with UMIN000044350.
开发了一种使用两根普通27G钝针和一根超薄30G针在巩膜隧道内固定人工晶状体（IOL）的新方法，该方法减少了眼内操作。制备半深度巩膜瓣，使用20G微型刀片或26G针在每个巩膜瓣下距肢体2毫米处进行垂直倾斜的巩膜切开术。两根弯曲的27G钝针连接巩膜切开术和角巩膜切口。一根袢在眼外插入该弯曲的27G钝针，并通过巩膜切开术部位挤出。将每个袢插入预先放置的超薄30G针的管腔内，并埋入巩膜隧道。在这项回顾性研究中，我们回顾了至少有3个月随访数据的患者中这项新技术的结果。在任何病例中均未观察到IOL的虹膜捕获，也未进行IOL重新定位。由眼内像差引起的散光与其他方法几乎相同。我们的技术可以在任何手术室进行，无需任何额外器械。本试验已在UMIN000044350注册。
