We present a modified technique for intrascleral fixation of a posterior chamber intraocular lens (IOL) without scleral flaps and assess its long-term safety and efficacy. The haptics of the IOL are externalized with a 23-gauge forceps and fixated in a scleral tunnel. Two clockwise scleral incisions are made using a 23-gauge needle at an angle 30 degrees above the sclera. A 3-piece IOL is inserted into the anterior chamber with an injector through the cornea incision, and the trailing haptic is kept outside to prevent the IOL from falling into the vitreous cavity. The leading haptic is held wit a forceps and extracted from the eye through the scleral incisions. The trailing haptic is held with a forceps and both haptics externalized onto the sclera. The conjunctival incisions are closed with 8-0 absorbable sutures tied to fixate 1 haptic (2 o'clock) after 1 more bite on the scleral bed.
我们提出了一种改良的技术，用于在不做巩膜瓣的情况下进行后房型眼内晶状体（IOL）巩膜内固定，并评估其长期安全性和有效性。用 23G 镊子将 IOL 的襻暴露，并将其固定在巩膜隧道内。用 23G 针头在巩膜上方以 30 度的角度做两个顺时针的巩膜切口。通过角膜切口用注射器将 3 件式 IOL 插入前房，将尾襻留在外面以防止 IOL 落入玻璃体腔。用镊子夹住前襻并通过巩膜切口将其从眼中取出。用镊子夹住尾襻并将两个襻暴露在巩膜上。用 8-0 可吸收缝线闭合结膜切口，将 1 个襻（2 点钟）固定在巩膜床上，再咬 1 口。
