To report a modified surgical technique for intrascleral intraocular lens (IOL) fixation with fewer anterior segment manipulations in eyes lacking sufficient capsular support.
Eyes from 14 patients who underwent 27-gauge needle-guided intrascleral IOL fixation with built-in 8-0 absorbable sutures were studied. The 8-0 absorbable sutures were inserted into 27-gauge round needles and used to create sclerotomies at the 4 o'clock and 10 o'clock positions under the scleral flap. The sutures were used to tie knots at the end of each haptic and guide haptic externalization through the sclerotomy. After externalization, a sufficient flange was created at the end of each haptic and fixed under the scleral flaps. The best corrected visual acuity (BCVA), corneal endothelial cell density (ECD), IOL tilt and decentration, previous surgery history, and complications were determined.
Fourteen cases were analyzed. The majority of eyes exhibited an improvement in the BCVA after surgery. When comparing the last follow-up to preoperative visual acuity, the mean change in BCVA was + 26.32 letters (p = 0.011). Postoperative complications included postoperative hypotony in 3 eyes, ocular hypertension in 2 eyes. No cases of postoperative cystoid macular edema (CME), vitreous hemorrhage (VH), IOL dislocation, or endophthalmitis were observed.
The 27-gauge needle-guided intrascleral IOL fixation technique with built-in 8-0 absorbable sutures is easy to perform with fewer anterior chamber manipulations and achieves both anatomical and optical stability.
报告一种改良的手术技术,用于在缺乏足够囊袋支持的眼中进行巩膜内眼内晶状体(IOL)固定,减少前节操作。
研究了 14 例患者的 27 号针引导巩膜内 IOL 固定术,这些患者均采用内置 8-0 可吸收缝线。8-0 可吸收缝线插入 27 号圆形针头中,在巩膜瓣下 4 点和 10 点位置创建巩膜隧道。缝线用于在每个襻的末端系结,并引导襻通过巩膜隧道外展。外展后,在每个襻的末端创建足够的翼,并将其固定在巩膜瓣下。测量最佳矫正视力(BCVA)、角膜内皮细胞密度(ECD)、IOL 倾斜和偏心、既往手术史和并发症。
分析了 14 例病例。大多数患者术后视力均有提高。与术前视力相比,最后一次随访时 BCVA 的平均变化为+26.32 个字母(p=0.011)。术后并发症包括 3 只眼术后低眼压、2 只眼高眼压。无术后囊样黄斑水肿(CME)、玻璃体积血(VH)、IOL 脱位或眼内炎发生。
27 号针引导巩膜内 IOL 固定术,采用内置 8-0 可吸收缝线,操作简单,前房操作较少,可实现解剖学和光学稳定性。
